glob

(PHP 4 >= 4.3.0, PHP 5)

glob — Find pathnames matching a pattern

Description

array glob ( string $pattern [, int $flags = 0 ] )

The glob() function searches for all the pathnames matching pattern according to the rules used by the libc glob() function, which is similar to the rules used by common shells.

Parameters

pattern

The pattern. No tilde expansion or parameter substitution is done.

flags

Valid flags:

  • GLOB_MARK - Adds a slash to each directory returned
  • GLOB_NOSORT - Return files as they appear in the directory (no sorting)
  • GLOB_NOCHECK - Return the search pattern if no files matching it were found
  • GLOB_NOESCAPE - Backslashes do not quote metacharacters
  • GLOB_BRACE - Expands {a,b,c} to match 'a', 'b', or 'c'
  • GLOB_ONLYDIR - Return only directory entries which match the pattern
  • GLOB_ERR - Stop on read errors (like unreadable directories), by default errors are ignored.

Return Values

Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on error.

Note: On some systems it is impossible to distinguish between empty match and an error.

Changelog

Version Description
5.1.0 GLOB_ERR was added
4.3.3 GLOB_ONLYDIR became available on Windows and other systems not using the GNU C library

Examples

Example #1 Convenient way how glob() can replace opendir() and friends.

<?php
foreach (glob("*.txt") as $filename) {
    echo "$filename size " . filesize($filename) . "\n";
}
?>

The above example will output something similar to:

funclist.txt size 44686
funcsummary.txt size 267625
quickref.txt size 137820

Notes

Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

Note: This function isn't available on some systems (e.g. old Sun OS).

Note: The GLOB_BRACE flag is not available on some non GNU systems, like Solaris.

here is a quick fix when nothing matches, glob will return false

<?php $files=glob('*.txt')?glob('*.txt'):array(); ?>

now you are able to use array function to $files.

A function to quickly remove a directory (works in seconds for a hundred thousand files)

<?php
/**
 * Remove the directory and its content (all files and subdirectories).
 * @param string $dir the directory name
 */
function rmrf($dir) {
    foreach (glob($dir) as $file) {
        if (is_dir($file)) {
            rmrf("$file/*");
            rmdir($file);
        } else {
            unlink($file);
        }
    }
}

Those of you with PHP 5 don't have to come up with these wild functions to scan a directory recursively: the SPL can do it.

<?php

$dir_iterator = new RecursiveDirectoryIterator("/path");
$iterator = new RecursiveIteratorIterator($dir_iterator, RecursiveIteratorIterator::SELF_FIRST);
// could use CHILD_FIRST if you so wish

foreach ($iterator as $file) {
    echo $file, "\n";
}

?>

Not to mention the fact that $file will be an SplFileInfo class, so you can do powerful stuff really easily:

<?php

$size = 0;
foreach ($iterator as $file) {
    if ($file->isFile()) {
        echo substr($file->getPathname(), 27) . ": " . $file->getSize() . " B; modified " . date("Y-m-d", $file->getMTime()) . "\n";
        $size += $file->getSize();
    }
}

echo "\nTotal file size: ", $size, " bytes\n";

?>

For those who need to recursively search a directory tree and cannot or wish not to call a function within itself here is another suggestion.

I tried the previously suggested listdirs_safe() and it didn't seem to find all subfolders in a directory tree.

There are two variations on the same theme.

Single Array.
<?php
$dir ='/dir';
while($dirs = glob($dir . '/*', GLOB_ONLYDIR)) {
  $dir .= '/*';
  if(!$d) {
     $d=$dirs;
   } else {
      $d=array_merge($d,$dirs);
   }
}
?>

Multiple arrays.
<?php
$n=0;
$dir ='/dir';
while($dirs = glob($dir . '/*', GLOB_ONLYDIR)) {
  $dir .= '/*';
  if(!$d) {
     $d=$dirs;
   } else {
     $d[$n]=$dirs;
   }
  $n++;
}
?>

This will result in the glob looping via "dir/*/*/*/*.." until it is no longer finding a directory structure.

First off, it's nice to see all of the different takes on this. Thanks for all of the great examples.

Fascinated by the foreach usage I was curious how it might work with a for loop. I found that glob was well suited for this, especially compared to opendir.  The for loop is always efficient when you want to protect against a potential endless loop.

$dir=$_SERVER['DOCUMENT_ROOT']."/test/directory_listing/test";
    echo $dir;
    $filesArray=glob($dir."/*.*");   
   
    $line.="<pre>";
    $line.=print_r($filesArray, true);
    $line.="</pre>";
    $line.="<hr>";
   
    for($i=0;$i<count($filesArray);$i++) {
        $line.=key($filesArray)." - ";   
        $line.=$filesArray[$i]."<br/>";
         next($filesArray);
    }

    echo $line;

Note that I pulled the glob array keys if you should need them.

Also you can tweak it for searches with something like this... (case sensitive)

$search_names="Somedocname";
$filesArray=glob($dir."/".$search_names."*.*");   
   
Enjoy!

If you want to use wildcard expressions (like they are used by glob() ) to search on strings, you can use this function:

<?php   
function match_wildcard( $wildcard_pattern, $haystack ) {
   $regex = str_replace(
     array("\*", "\?"), // wildcard chars
     array('.*','.'),   // regexp chars
     preg_quote($wildcard_pattern)
   );

   return preg_match('/^'.$regex.'$/is', $haystack);
}

$test = "foobar and blob\netc.";
var_dump(
    match_wildcard('foo*', $test),      // TRUE
    match_wildcard('bar*', $test),      // FALSE
    match_wildcard('*bar*', $test),     // TRUE
    match_wildcard('**blob**', $test),  // TRUE
    match_wildcard('*a?d*', $test),     // TRUE
    match_wildcard('*etc**', $test)     // TRUE
);
?>

You can use multiple asterisks with the glob() - function.

Example:

<?php
  $paths = glob('my/*/dir/*.php');
?>

$paths will contains paths as following examples:

- my/1/dir/xyz.php
- my/bar/dir/bar.php
- my/bar/dir/foo.php

Referring to the recursive glob() function below (http://sg.php.net/manual/en/function.glob.php#87221):

It does not work when the pattern contains a directory name. Here's a fixed version:

<?php
function rglob($pattern, $flags = 0, $path = '') {
    if (!$path && ($dir = dirname($pattern)) != '.') {
        if ($dir == '\\' || $dir == '/') $dir = '';
        return rglob(basename($pattern), $flags, $dir . '/');
    }
    $paths = glob($path . '*', GLOB_ONLYDIR | GLOB_NOSORT);
    $files = glob($path . $pattern, $flags);
    foreach ($paths as $p) $files = array_merge($files, rglob($pattern, $flags, $p . '/'));
    return $files;
}
?>

(continuation from previous post)

glob's regex does not offer any kind of quantification of a specified character or character class or alternation.  For instance, if you have the following files:

a.php
aa.php
aaa.php
ab.php
abc.php
b.php
bc.php

with pcre regex you can do ~^a+\.php$~ to return

a.php
aa.php
aaa.php

This is not possible with glob.  If you are trying to do something like this, you can first narrow it down with glob, and then get exact matches with a full flavored regex engine.  For example, if you wanted all of the php files in the previous list that only have one or more 'a' in it, you can do this:

<?php
   $list = glob("a*.php");
   foreach ($list as $l) {
      if (preg_match("~^a+\.php$~",$file))
         $files[] = $l;
   }
?>

glob also does not support lookbehinds, lookaheads, atomic groupings, capturing, or any of the 'higher level' regex functions.

glob does not support 'shortkey' meta-characters like \w or \d.

Since I feel this is rather vague and non-helpful, I thought I'd make a post detailing the mechanics of the glob regex.

glob uses two special symbols that act like sort of a blend between a meta-character and a quantifier.  These two characters are the * and ?

The ? matches 1 of any character except a /
The * matches 0 or more of any character except a /

If it helps, think of the * as the pcre equivalent of .* and ? as the pcre equivalent of the dot (.)

Note: * and ? function independently from the previous character. For instance, if you do glob("a*.php") on the following list of files, all of the files starting with an 'a' will be returned, but * itself would match:

a.php // * matches nothing
aa.php // * matches the second 'a'
ab.php // * matches 'b'
abc.php // * matches 'bc'
b.php // * matches nothing, because the starting 'a' fails
bc.php // * matches nothing, because the starting 'a' fails
bcd.php // * matches nothing, because the starting 'a' fails

It does not match just a.php and aa.php as a 'normal' regex would, because it matches 0 or more of any character, not the character/class/group before it.

Executing glob("a?.php") on the same list of files will only return aa.php and ab.php because as mentioned, the ? is the equivalent of pcre's dot, and is NOT the same as pcre's ?, which would match 0 or 1 of the previous character.

glob's regex also supports character classes and negative character classes, using the syntax [] and [^]. It will match any one character inside [] or match any one character that is not in [^].

With the same list above, executing

glob("[ab]*.php) will return (all of them):
a.php  // [ab] matches 'a', * matches nothing
aa.php // [ab] matches 'a', * matches 2nd 'a'
ab.php // [ab] matches 'a', * matches 'b'
abc.php // [ab] matches 'a', * matches 'bc'
b.php // [ab] matches 'b', * matches nothing
bc.php // [ab] matches 'b', * matches 'c'
bcd.php // [ab] matches 'b', * matches 'cd'

glob("[ab].php") will return a.php and b.php

glob("[^a]*.php") will return:
b.php // [^a] matches 'b', * matches nothing
bc.php // [^a] matches 'b', * matches 'c'
bcd.php // [^a] matches 'b', * matches 'cd'

glob("[^ab]*.php") will return nothing because the character class will fail to match on the first character.

You can also use ranges of characters inside the character class by having a starting and ending character with a hyphen in between.  For example, [a-z] will match any letter between a and z, [0-9] will match any (one) number, etc..

glob also supports limited alternation with {n1, n2, etc..}.  You have to specify GLOB_BRACE as the 2nd argument for glob in order for it to work.  So for example, if you executed glob("{a,b,c}.php", GLOB_BRACE) on the following list of files:

a.php
b.php
c.php

all 3 of them would return.  Note: using alternation with single characters like that is the same thing as just doing glob("[abc].php").  A more interesting example would be glob("te{xt,nse}.php", GLOB_BRACE) on:

tent.php
text.php
test.php
tense.php

text.php and tense.php would be returned from that glob.

I lost hours looking for the solution for this problem.
glob() wasn't eating up my directory names (stuff like "foobar[]"), and I searched online for some hours, I tried preg_quote to no avail.

I finally found the proper way to escape stuff in glob() in an obscure Python mailing list:

<?php
preg_replace('/(\*|\?|\[)/', '[$1]', $dir_path);
?>

If you want to add a directory path before your pattern, you should do it like this:

<?php
glob(preg_replace('/(\*|\?|\[)/', '[$1]', $dir_path).'*.txt');
?>
preg_quote WILL NOT work in all cases (if any).

glob() (array_sum() and array_map() in fact too) can be very useful if you want to calculate the sum of all the files' sizes located in a directory:

<?php
$bytes = array_sum(array_map('filesize',glob('*')));
?>

Unfortunately there's no way to do this recursively, using glob() (as far as I know).
miah [at] miahs [dot] de

You should use preg_quote every time you want to add a path to an directory.

Use it like this:

<?php

$dir = './mydir/[with]/special/.chars/';
$file = '[a-z]+\.txt';

$files = glob( preg_quote( $dir, DIRECTORY_SEPARATOR ) . $file );

if($files !== false && count($files) != 0)
{
    // Do something with the files
}

?>

Reason:

Special chars like [ or . will match in regular expressions so "/dir/[special]/*.txt" will match on all files in the dirs

/dir/s/, /dir/p/, /dir/e/, /dir/c/, /dir/i/, /dir/a/, /dir/l/

I hope i could help.

Here is a function that returns specific files in an array, with all of the details. Includes some basic garbage checking.

Variables

$source_folder // the location of your files
$ext // file extension you want to limit to (i.e.: *.txt)
$sec // if you only want files that are at least so old.

The function

function glob_files($source_folder, $ext, $sec, $limit){
    if( !is_dir( $source_folder ) ) {
        die ( "Invalid directory.\n\n" );
    }
   
    $FILES = glob($source_folder."\*.".$ext);
    $set_limit    = 0;
   
    foreach($FILES as $key => $file) {
   
        if( $set_limit == $limit )    break;
       
        if( filemtime( $file ) > $sec ){
       
            $FILE_LIST[$key]['path']    = substr( $file, 0, ( strrpos( $file, "\\" ) +1 ) );
            $FILE_LIST[$key]['name']    = substr( $file, ( strrpos( $file, "\\" ) +1 ) );   
            $FILE_LIST[$key]['size']    = filesize( $file );
            $FILE_LIST[$key]['date']    = date('Y-m-d G:i:s', filemtime( $file ) );
            $set_limit++;
       
        }
       
    }
    if(!empty($FILE_LIST)){
        return $FILE_LIST;
    } else {
        die( "No files found!\n\n" );
    }
}

So....

$source_folder = "c:\temp\my_videos";
$ext = "flv"; // flash video files
$sec = "7200"; // files older than 2 hours
$limit = 2;

print_r(glob_files($source_folder, $ext, $sec, $limit));

Would return:

Array
(
    [0] => Array
        (
            [path] => c:\temp\my_videos\
            [name] => fluffy_bunnies.flv
            [size] => 21160480
            [date] => 2007-10-30 16:48:05
        )

    [1] => Array
        (
            [path] => c:\temp\my_videos\
            [name] => synergymx.com.flv
            [size] => 14522744

As a follow up to recursively determining all paths (by viajy at yoyo dot org) and opendir being faster than glob (by Sam Yong - hellclanner at live [dot] com).

The list all dirs code didn't seem to work, at least on my server (provided by parazuce [at] gmail [dot] com).

I needed a function to create an unlimited multidimensional array, with the names of the folders/files intact (no realpath's, although that is easily possible). This is so I can simply loop through the array, create an expandable link on the folder name, with all the files inside it.

This is the correct way to recurse I believe (no static, return small arrays to build up the multidimensional array), and includes a check for files/folders beginning with dots.

// may need modifications

function list_files($path)
{
    $files = array();
   
    if(is_dir($path))
    {
        if($handle = opendir($path))
        {
            while(($name = readdir($handle)) !== false)
            {
                if(!preg_match("#^\.#", $name))
                if(is_dir($path . "/" . $name))
                {
                    $files[$name] = list_files($path . "/" . $name);
                }
                else
                {
                    $files[] = $name;
                }
            }
           
            closedir($handle);
        }
    }

    return $files;
}

print_r(list_files("/path/to/folder"));

// example usage

function list_html($list)
{
    $html = "";
   
    foreach($list as $folder => $file)
    {
        if(is_array($list[$folder]))
        {
            $html .= "> (folder) " . $folder . "<br>";
            $html .= list_html($list[$folder]);
        }
        else
        {
            $html .= " (file) " . $file . "<br>";
        }
    }
   
    return $html;
}

echo list_html(list_files("/path/to/folder"));

As a response to a post by viajy at yoyo dot org on 10-Feb-2007 04:50, he posted the following code:
<?php
function listdirs($dir) {
    static $alldirs = array();
    $dirs = glob($dir . '/*', GLOB_ONLYDIR);
    if (count($dirs) > 0) {
        foreach ($dirs as $d) $alldirs[] = $d;
    }
    foreach ($dirs as $dir) listdirs($dir);
    return $alldirs;
}
?>

It is not best practice to use recursive functions like that, so I wrote a safe (non-recursive) function below:

<?php
function listdirs_safe($start)
{
    $dir  = $start;
    $dirs = array();
    $next = 0;

    while (true)
    {
        $_dirs = glob($dir.'/*', GLOB_ONLYDIR);

        if (count($_dirs) > 0)
        {
            foreach ($_dirs as $key => $_dir)
                $dirs[] = $_dir;
        }
        else
            break;
           
        $dir = $dirs[$next++];
    }
   
    return $dirs;
}
?>

Example:

print_r(listdirs_safe('*'));

Output:
Array
(
    [0] => Dummy folder/Dummy folder 2
    [1] => Dummy folder/Dummy folder 2/Dummy Folder 3
    [2] => Dummy folder/Dummy folder 2/Dummy Folder 3/4
    [3] => Dummy folder/Dummy folder 2/Dummy Folder 3/Dummy folder 4
    [4] => Dummy folder/Dummy folder 2/Dummy Folder 3/4/5
)

Do note that this command has a security hole.
If the $path or $pattern given includes special characters, for example a command substitution such as "`rm index.php`", the shell will process it and execute that command.

You can fix the problem by either escaping the characters properly (use shell_escape) or by writing a function that actually calls glob(), or opendir()/readdir()/closedir(), recursively.

As mentioned below, characters like [ and ] cause problems and need to be escaped with a backslash. But it's *not* enough to escape them in the pattern itself! If they appear in the path to the working directory, glob() also fails!

So, if this fails:

glob('*.txt');

Try:

glob(preg_quote(getcwd() . DIRECTORY_SEPARATOR) . '*.txt');

Run your directory + "file pattern" through preg_quote to get around [ ] / etc issues...glob uses pattern matching.

glob() does not work if the path contains brackets "[" and "]".

For example, this will make it fail:

$files = glob("[myfolder]/*.txt");

No error is returned, just an empty array!

Hi there,
if you backslash the brackets, it should work. Try:
$files = glob("\[myfolder\]/*.txt");
Hope this helps.

An alternative to this glob function. Like what edogs [at] dogsempire.com said, opendir should be faster than glob. I have not tested timing for this function but it works perfectly for me on my PHP v5.2.2 server.

<?php

$_foo ='/server/public_html/path/';

function s_glob($dir){
$files = array();
if(is_dir($dir)){
    if($dh=opendir($dir)){
    while(($file = readdir($dh)) !== false){
        $files[]=$dir.$file;
    }}
}
return $files;
}

print_r(s_glob($_foo));

?>

This function returns an empty array if no files are found in the directory or the path specified is not a directory.

if your script runs in a directory which contains brackets "[" and "]" glob does not work. example:

script path: c:/dir1/[baddir]/dir2/script.php

íf you use glob("c:/*") or similar calls in this script, it will fail!!

you do not even have to use the brackets in the first parameter of glob!

I think redcube at gmx dot de's comment @ http://uk3.php.net/manual/en/function.glob.php#68869 should be added to the manual entry for this function, very useful information when trying to get every single file in a directory.

Something I used to sort dir & subdir into array (multidimensional) reflecting dir structure.

    function getRecursiveFolderList($curDir,$currentA=false)
      {                   
        $dirs = glob($curDir . '/*', GLOB_ONLYDIR);    
       
        $cur = 0;
        foreach($dirs as $dir)
          {
            $currentA[$cur]['path'] = $dir;
            $currentA[$cur] = $this->getRecursiveFolderList($dir,$currentA[$cur]);
               
            ++$cur;
          }

        return $currentA;
      }

Reply to ny_obaATgmxDOTnet:

You could also use sql_regcase() to build a pattern for case insensitive matches.
You may also want to set the locale before, so it is used when building the pattern.

<?php

$pattern = sql_case("*.pdf");

var_dump(glob($pattern));

?>

should therefore match file.pdf AND OtherFile.PDF

See http://www.php.net/sql_regcase for more information.

A couple of notes:
glob() handles symbolic filesystem links and resolves references to './', '../'  nicely and handles an extra '/' character , at least on X-systems. e.g., glob("../*") will do next higher dir.

This is good to use so warnings or errors show as "../foo" and not your system's full path. 

Several of the examples use a notation "*.*" when just plain "*" does the same thing.  The "*.*" notation is misleading as it implies foo.ext will not be found with "*" because the "." is not present.

Watch the flags must not be strings. They are defined constants. Thus,
glob("../*", GLOB_ONLYDIR)  works;
glob("../*", "GLOB_ONLYDIR")  does not.

this is a recursive function i wrote to return an array of all subdirectories of a dir

function listdirs($dir) {
    static $alldirs = array();
    $dirs = glob($dir . '/*', GLOB_ONLYDIR);
    if (count($dirs) > 0) {
        foreach ($dirs as $d) $alldirs[] = $d;
    }
    foreach ($dirs as $dir) listdirs($dir);
    return $alldirs;
}

example:
print_r(listdirs('/some/path'));

Maybe all of you still know this, but it seems that if the directory contains some unresolved symlink, glob() simply ignore those files.

Here is simple function that will find and remove all files (except "." ones) that match the expression ($match, "*" as wildcard) under starting directory ($path) and all other directories under it.

function rfr($path,$match){
   static $deld = 0, $dsize = 0;
   $dirs = glob($path."*");
   $files = glob($path.$match);
   foreach($files as $file){
      if(is_file($file)){
         $dsize += filesize($file);
         unlink($file);
         $deld++;
      }
   }
   foreach($dirs as $dir){
      if(is_dir($dir)){
         $dir = basename($dir) . "/";
         rfr($path.$dir,$match);
      }
   }
   return "$deld files deleted with a total size of $dsize bytes";

In some systems (AIX for example) GLOB_BRACE isn't defined and you get the error:
glob() expects parameter 2 to be long, string given in /XX/XX.php

<?

foreach (glob("{*.pdf,*.PDF}",GLOB_BRACE ) as $filename) {
      echo "$filename \n";
}

?>

The method may help you in this case.

<?

foreach (array_merge(glob("*.pdf"),glob("*.PDF")) as $filename) {
      echo "$filename \n";
}

The answer for the difference in the dirsize function of "management at twilightus dot net":

glob('*') ignores all 'hidden' files by default. This means it does not return files that start with a dot (e.g. ".file").
If you want to match those files too, you can use "{,.}*" as the pattern with the GLOB_BRACE flag.

<?php
// Search for all files that match .* or *
$files = glob('{,.}*', GLOB_BRACE);
?>

Note: This also returns the directory special entries . and ..

I was making a directory filesize function but found there's a slight difference between glob and readdir in terms of getting sizes.

<?php
function dirsize_glob($dir)
{
    $size = 0;
    $dir .= (!ereg('/$', $dir)) ? '/' : '';

    foreach (glob($dir . '*') as $file)
    {
        $size += (is_dir($file)) ? dirsize_glob($file) : filesize($file);
    }

    return $size;
}

function dirsize_readdir($dir)
{
    $size = 0;
    $dir .= (!ereg('/$', $dir)) ? '/' : '';

    $handle = opendir($dir);
    while (($file = readdir($handle)) !== FALSE)
    {
        if (!ereg('^\.{1,2}$', $file))
        {
            $size += (is_dir($dir . $file)) ? dirsize_readdir($dir . $file) : filesize($dir . $file);
        }
    }
    closedir($handle);

    return $size;
}
?>

For a directory that's 529216 bytes, readdir correctly gives 529216 while glob gives 528996, a difference of 220 bytes. Anyone know why there's such a difference?

If there is no glob result, 4.4.2 return empty array but 4.3.8 returns FALSE.

code:

I have been working towards a CMS-type design that is both modular and quite flat. For example, included files are all one level below the installation folder.

glob() just help me get rid of a lot of opendir() hassle. I wasn't sure if the double asterix would work - but it's fine:

foreach (glob(SERVER_PATH."/*/includes/*.php") as $inc) {
   require($inc);
}

I've written a function that I've been using quite a lot over the past year or so. I've built whole websites and their file based CMSs based on this one function, mostly because (I think) databases are not as portable as groups of files and folders. In previous versions, I used opendir and readdir to get contents, but now I can do in one line what used to take several. How? Most of the work in the whole script is done by calling

glob("$dir/*")

Giving me an array containing the names of the items in the folder, minus the ones beginning with '.', as well as the ones I specify.

<?php

/* alpharead version 3: This function returns an array containing the names of the files inside any given folder, excluding files that start with a '.', as well as the filenames listed in the '$killit' array. This array is sorted using the 'natural alphabetical' sorting manner. If no input is given to the function, it lists items in the script's interpreted folder. Version 3 fixes a MAJOR bug in version 2 which corrupted certain arrays with greater than 5 keys and one of the supposedly removed filenames.
written by Admiral at NuclearPixel.com */

function alpharead3($dir){
if(!$dir){$dir = '.';}
foreach(glob("$dir/*") as $item){$sort[]= end(explode('/',$item));}

$killit = array('index.html', 'index.php', 'thumbs.db', 'styles.css');
$killcounter = 0;
foreach($sort as $sorteditem){
foreach($killit as $killcheck){
if(strtolower($sorteditem) == strtolower($killcheck))
{unset($sort[$killcounter]);}
}$killcounter++;}
if($sort){natsort($sort);}
foreach($sort as $item){$return[]= $item;}

if(!$return){return array();}
return $return;
}

//some basic usage

$folder = 'images';
foreach(alpharead3($folder) as $item)
{
echo '<img src="'.$folder.'/'.$item.'"><br>'.$item."\n";
}

?>

Commens on this function are welcome!

Note that on Windows, glob distinguishes between uppercase and lowercase extensions, so if the directory contains a file "test.txt" and you glob for "*.TXT" then the file will not be found!
That bug only happens when you use patterns containing "*", like the example above. If you for example search for the full filename "test.TXT" then everything works correctly.
DMan
28-Aug-2005 09:59
Whilst on Windows, a path starting with a slash resolves OK for most file functions - but NOT glob.
If the server is LAUNCHED (or chdir()ed) to W:, then
file_exists("/temp/test.txt")
returns true for the file "W:/temp/test.txt".
But glob("/temp/*.txt") FAILS to find it!

A solution (if you want to avoid getting drive letters into your code) is to chdir() first, then just look for the file.
<?php
$glob="/temp/*.txt";
chdir(dirname($glob));
// getcwd() is now actually "W:\temp" or whatever

foreach (glob(basename($glob)) as $filename) {
   $filepath = dirname($glob)."/".$filename; // must re-attach full path
   echo "$filepath size " . filesize($filepath) . "\n";
}
?>

Note also, glob() IS case sensitive although most other file funcs on Windows are not.

This is a replacement for glob on servers that are running a php version < 4.3

It supports * and ? jokers, and stacking of parameters with ; 

So you can do

<? $results=glob('/home/user/*.txt;*.doc') ?>

And it will return an array of matched files. 

As is the behaviour of the built-in glob function, this one will also return boolean false if no matches are found, and will use the current working directory if none is specified.

<?php
if(!(function_exists('glob')))
{function glob($pattern)
 {#get pathname (everything up until the last / or \)
  $path=$output=null;
  if(PHP_OS=='WIN32')
   $slash='\\';
  else
   $slash='/';
  $lastpos=strrpos($pattern,$slash);
  if(!($lastpos===false))
  {$path=substr($pattern,0,-$lastpos-1); #negative length means take from the right
   $pattern=substr($pattern,$lastpos);
  }
  else
  {#no dir info, use current dir
   $path=getcwd();
  }
  $handle=@ opendir($path);
  if($handle===false)
   return false;
  while($dir=readdir($handle))
  {if(pattern_match($pattern,$dir))
    $output[]=$dir;
  }
  closedir($handle);
  if(is_array($output))
   return $output;
  return false;
 }

 function pattern_match($pattern,$string)
 {#basically prepare a regular expression
  $out=null;
  $chunks=explode(';',$pattern);
  foreach($chunks as $pattern)
  {$escape=array('$','^','.','{','}',
                 '(',')','[',']','|');
   while(strpos($pattern,'**')!==false)
    $pattern=str_replace('**','*',$pattern);
   foreach($escape as $probe)
    $pattern=str_replace($probe,"\\$probe",$pattern);
   $pattern=str_replace('?*','*',
             str_replace('*?','*',
              str_replace('*',".*",
               str_replace('?','.{1,1}',$pattern))));
   $out[]=$pattern;
  }
  if(count($out)==1)
   return(eregi("^$out[0]$",$string));
  else
   foreach($out as $tester)
    if(eregi("^$tester$",$string))
     return true;
   return false;
 }
}
?>

This function is case insensitive, but if needed, you can do this to make it behave depending on os:

* replace eregi in the example with my_regexp

add this function
<?php
function my_regexp($pattern,$probe)
{$sensitive=(PHP_OS!='WIN32');
  $sensitive=false;
 return ($sensitive?
     ereg($pattern,$probe):
     eregi($pattern,$probe));
}

In regards to the comments made by: NOSPAM sketch at infinite dot net dot au, he is wrong about Unix/Linux (I can't speak for Windows).  I am running PHP 5.0.4 and I ran a bunch of different tests on relative and absolute paths using the glob function and they all work on Unix/Linux.  I also tested glob on empty directories and patterns which don't match any files (even directories or files which don't exist) and it __always__ returns an empty array.  I couldn't get the glob function to return false so it looks like it always returns an array.

Here is a way I used glob() to browse a directory, pull the file name out, resort according to the most recent date and format it using date(). I called the function inside a <select> and had it go directly to the PDF file:

function browsepdf(){
    $pdffile=glob("printable/*.pdf");
    rsort($pdffile);
    foreach($pdffile as $filename){
        $filename=ltrim($filename, "printable/");
        $filename=rtrim($filename, ".pdf");
        $file=$filename;
        $datetime=strtotime($filename);
        $newdate=strtotime("+3 days",$datetime);
        $filenamedate=date("F d", $datetime);
        $filenamedate.=" - ".date("F d, Y", $newdate);
        echo "<option value='$file'>$filenamedate</option>";
    }
}

glob caused me some real pain in the buttom on windows, because of the DOS thing with paths (backslashes instead of slashes)...

This was my own fault because I "forgot" that the backslash, when used in strings, needs to be escaped, but well, it can cause a lot of confusion, even for people who are not exactly newbies anymore...

For some reason, I didn't have this problem with other file operations (chdir, opendir, etc...), which was the most confusing of all...

So, for people running scripts on Windows machines (Dos95, 98 or WinNT or DosXP), just remember this:

glob('c:\temp\*.*'); // works correctly, returns an array with files.
glob("c:\temp\*.*"); // does NOT work... the backslashes need to be escaped...
glob("c:\\temp\\*.*"); // that works again...

This is especially confusing when temporary writable directories are returned as an unescaped string.

$tempdir = getenv('TEMP');
// this returns "C:\DOCUME~1\user\LOCALS~1\Temp"
so in order to scan that directoy I need to do:

glob($tempdir . "\\*.*");

Or perhaps it's easier to replace all backslashes with slashes in order to avoid these kinds of confusions...

glob("c:/temp/*.*"); // works fine too...

I know I'm not contributing anything new here, but I just hope this post may avoid some unnecessary headaches...

in the example below, i found i got an error if the directory was empty.

<?php
foreach (glob("*.txt") as $filename) {
   echo "$filename size " . filesize($filename) . "\n";
}
?>

I think its because glob()'ing an empty directory returns false, and so calling foreach (false as $value) will obviously break.

to fix this, i did the following:
<?php
$files = glob("*.txt) or array(); // give it an empty array if the directory is empty or glob fails otherwise
   echo "$filename size " . filesize($filename) . "n";
}
?>

Hope this helps someone

Be aware...

On Windows you need to add "/" mark:
<?php
$files = glob("/dir/*.txt"); // Works properly.
$files = glob("dir/*.txt"); // Failure!, first letter is missing on every filename!
?>

On Unix you cant add the "/" mark:
<?php
$files = glob("dir/*.txt"); // Works properly.
$files = glob("/dir/*.txt"); // No files found!
?>

Hope this will save your time :)

The example on this page will generate a warning if the glob function does not find any filenames that match the pattern.

The glob function result will only be an array if it finds some files and the foreach statement requires its argument to be an array.

By checking for the possibility that the result of the glob function may not be an array you can eliminate the warning.

Here's a better example:

<?php
$matches = glob("*.txt");
if ( is_array ( $matches ) ) {
   foreach ( $matches as $filename) {
      echo "$filename size " . filesize($filename) . "\n";
   }
}
?>

Just threw this together in response to a common question in irc:

Available at: http://www.pgregg.com/projects/
http://www.pgregg.com/projects/php/code/preg_find.phps

preg_find() - A function to search in a directory for files or directories matching a preg_ pattern.  Tell it the pattern, the start directory and some optional flags and it will return an array of files and their associated stat() details.  If you just want the filenames, just do an array_keys() on the result.

e.g. $files = preg_find("/\.php$/", '.', PREG_FIND_RECURSIVE);
will find all files ending in .php in the current directory and below.

Options are:
// PREG_FIND_RECURSIVE  - go into subdirectorys looking for more files
// PREG_FIND_DIRMATCH   - return directorys that match the pattern also
// PREG_FIND_FULLPATH   - search for the pattern in the full path (dir+file)
// PREG_FIND_NEGATE     - return files that don't match the pattern
// to use more than one simple seperate them with a | character

Hope you find it useful.

Paul.

Be aware that on UNIX, * as the pattern will *not* match dot-files and dot-directories.  Knowing this will save you some headache.  :-)  May He bless you.

Note that, in some configurations, the search is case-sensitive! You'll need to have something like:

<?php
$images = glob("/path/to/images/{*.jpg,*.JPG}", GLOB_BRACE);
?>

Also on some servers, I have seen such scripts 'crash' with an CGI Error ("...not returning a complete set of HTTP headers...") when glob could not find any match!

Here's an example of how to use the GLOB_BRACE flag:

<?php
$images = glob("/path/to/images/{*.gif,*.jpg,*.png}", GLOB_BRACE);
?>

It's also worth noting that when using the GLOB_BRACE flag in any version of PHP prior to 4.3.4, PHP will crash if no matches are found.

If you don't have PHP >= 4.3 available and don't want to hassle with PHP (:-) do something like this on GNU/Linux:

<?php
foreach (explode("\n",`find -type d -maxdepth 1 ! -name ".*" -printf "%f\n" `) as $dirname) {
    print $dirname;
}
?>

With the "find" you can "glob" whatever you like.

I have written my own function for searching files, but it only supports ? and *
However it should be easily expandable.

<?php
// e.g. $matches=GetMachingFiles(GetContents("."),"*.txt");
function GetMatchingFiles($files, $search) {

    // Split to name and filetype
    if(strpos($search,".")) {
      $baseexp=substr($search,0,strpos($search,"."));
      $typeexp=substr($search,strpos($search,".")+1,strlen($search));
    } else {
      $baseexp=$search;
      $typeexp="";
    }
    
    // Escape all regexp Characters
    $baseexp=preg_quote($baseexp);
    $typeexp=preg_quote($typeexp);
    
    // Allow ? and *
    $baseexp=str_replace(array("\*","\?"), array(".*","."), $baseexp);
    $typeexp=str_replace(array("\*","\?"), array(".*","."), $typeexp);
       
    // Search for Matches
    $i=0;
    foreach($files as $file) {
      $filename=basename($file);
       
      if(strpos($filename,".")) {
        $base=substr($filename,0,strpos($filename,"."));
        $type=substr($filename,strpos($filename,".")+1,strlen($filename));
      } else {
        $base=$filename;
        $type="";
      }

      if(preg_match("/^".$baseexp."$/i",$base) && preg_match("/^".$typeexp."$/i",$type))  {
        $matches[$i]=$file;
        $i++;
      }
    }
    return $matches;
}

And if someone's searching for a function which gets all files from a directory including the subdirectories:

// Returns all Files contained in given dir, including subdirs
function GetContents($dir,$files=array()) {
  if(!($res=opendir($dir))) exit("$dir doesn't exist!");
  while(($file=readdir($res))==TRUE)
    if($file!="." && $file!="..")
      if(is_dir("$dir/$file")) $files=GetContents("$dir/$file",$files);
        else array_push($files,"$dir/$file");
     
  closedir($res);
  return $files;
}

?>

Since this function is a wrapper for the OS function of the same name, you may find it helpful to look at the man page while the exact PHP implementation is sorted out.

You might have some luck passing in the literal values of the constants defined in /usr/include/glob.h.  For example, GLOB_NOSORT is defined as (1 << 2), which is 4.  In PHP, glob('*.php', 4) will returns an unsorted list for me in RH 7.x.  YMMV.

If this function is not available in your version of PHP, think looking at the 'Directory Functions' which can be used instead.
