str_getcsv
I'm really sorry, there is a big bug in my previous mb_str_ireplace function: here's the correct one:
<?php
/**
* Case insensitive multi-byte safe str_ireplace
* @param string $search
* @param string $replace
* @param string $subject
* @param int $count
* @param string $encoding
* @return string
*/
function mb_str_ireplace($search, $replace, $subject, $count = null, $encoding = u8) {
$l1 = mb_strlen($search, $encoding);
$l2 = mb_strlen($replace, $encoding);
$rc = 0;
$offset = 0;
while(ok($p = mb_stripos($subject, $search, $offset, $encoding)) && (is_null($count) || $rc <= $count)) {
if (ok($p))
$subject = mb_substr($subject, 0, $p, $encoding) . $replace . mb_substr($subject, $p + $l1, mb_strlen($subject, $encoding), $encoding);
$offset = $p + $l2;
$rc++;
}
return $subject;
}
?>
To make it mb_str_replace - change stripos to strpos. I'm sorry for previous bug, well, this one is tested.
I wonder should I publish my growing mb_ functions library like WORKING mb_wordwrap WITHOUT regexes (faster)... E-mail me.
Descripción
Esta función devuelve una cadena o una matriz con todas las ocurrencias de busqueda en asunto (ignorando mayúsculas y minúsculas) sustituidas por el reemplazo dado. Si no necesita reglas de reemplazo sofisticadas, usted debería, por lo general, usar esta función en lugar de eregi_replace() o preg_replace() con el modificador i.
Lista de parámetros
- busqueda
-
Note: Cada reemplazo con la matriz busqueda es realizado en el resultado del reemplazo previo.
- reemplazo
-
- asunto
-
Si asunto es una matriz, entonces las búsquedas y reemplazos son realizados con cada entrada de asunto , y el valor devuelto es asimismo una matriz.
- conteo
-
El número de agujas coincidentes y reemplazadas será devuelto en conteo , que es pasado por referencia.
Si busqueda y reemplazo son matrices, entonces str_ireplace() toma un valor de cada matriz y los usa para realizar las búsquedas y reemplazos sobre asunto . Si reemplazo tiene menos valores que busqueda , entonces se usa una cadena vacía para el resto de valores de reemplazo. Si busqueda es una matriz y reemplazo es una cadena, entonces esta cadena de reemplazo es usada para cada valor de busqueda .
Valores retornados
Devuelve una cadena o una matriz de reemplazos.
Registro de cambios

It's obvious str_ireplace() won't be multi-byte safe. Function mb_str_ireplace() is missing in php, so here's mine:
<?php
/**
* Case insensitive multi-byte safe str_replace
* @param string $search
* @param string $replace
* @param string $subject
* @param int $count
* @param string $encoding
* @return string
*/
function mb_str_ireplace($search, $replace, $subject, $count = null, $encoding = 'utf-8') {
$l1 = mb_strlen($search, $encoding);
$rc = 0;
$offset = 0;
while (ok($p = mb_stripos($subject, $search, $offset, $encoding)) && (is_null($rc) || $rc <= $count)) {
if (ok($p)) $subject = mb_substr($subject, $offset, $p, $encoding) . $replace . mb_substr($subject, $p + $l1, mb_strlen($subject, $encoding), $encoding);
$offset = $p + $l1;
$rc++;
}
return $subject;
}
?>
It works exactly like original str_ireplace() and defaults to 'utf-8' encoding. Replace with null if you like. Well, it's surely slower than built-in functions, however it's one of the fastest ways to do the trick.

My apologies. I'm a PHP newbie and the count function on my script below didn't work right if you have more than one "keyword". I searched and spent a long time to get this to work right, so wanted to share it.
This is very easy to use by doing the following.
$text - is the text to search
$words - are the words to highlight (search text)
$the_place - is so that you can tell your users what "area" was searched.
<?php
function highlight_this($text, $words, $the_place) {
$words = trim($words);
$the_count = 0;
$wordsArray = explode(' ', $words);
foreach($wordsArray as $word) {
if(strlen(trim($word)) != 0)
//exclude these words from being replaced
$exclude_list = array("word1", "word2", "word3");
// Check if it's excluded
if ( in_array( strtolower($word), $exclude_list ) ) {
} else {
$text = str_ireplace($word, "<span class=\"highlight\">".strtoupper($word)."</span>", $text, $count);
$the_count = $count + $the_count;
}
}
//added to show how many keywords were found
echo "<br><div class=\"emphasis\">A search for <strong>" . $words. "</strong> found <strong>" . $the_count . "</strong> matches within the " . $the_place. ".</div><br>";
return $text;
}
//example of how to use
$text_to_highlight = highlight_this($text_to_highlight, $search_text, "Place you searched");
?>

I modified a script from notes on the eregi_replace() function page. This is a highlight script that worked good for me.
$text - is the text to search
$words - are the words to highlight (search text)
$the_place - is so that you can tell your users what "area" was searched.
<?php
function highlight_this($text, $words, $the_place) {
$words = trim($words);
$wordsArray = explode(' ', $words);
foreach($wordsArray as $word) {
if(strlen(trim($word)) != 0)
$text = str_ireplace($word, "<span class=\"highlight\">".strtoupper($word)."</span>", $text, $count);
}
//added to show how many keywords were found
echo "<br><div class=\"emphasis\">A search for <strong>" . $words. "</strong> found <strong>" . $count . "</strong> matches within the " . $the_place. ".</div><br>";
//end script modification
return $text;
}
?>

Here are some minor tweaks to-n00b-at-battleofthebits-dot-org's excellent function.
1) The token was set to an ASCII value 1 (which could be changed as was previously noted)
2) The $c++ was not needed
3) The while statement is not necessary for the final replacement
4) Note that this does not allow use of arrays for search and replace terms. That could be implemented using loops.
<?php
if(!function_exists('str_ireplace')){
function str_ireplace($search,$replace,$subject){
$token = chr(1);
$haystack = strtolower($subject);
$needle = strtolower($search);
while (($pos=strpos($haystack,$needle))!==FALSE){
$subject = substr_replace($subject,$token,$pos,strlen($search));
$haystack = substr_replace($haystack,$token,$pos,strlen($search));
}
$subject = str_replace($token,$replace,$subject);
return $subject;
}
}
?>

Dreamhost hasn't upgraded to PHP 5.0 -- I came up with my own alternative, trying to make it run as much like str_ireplace() as possible. Adjust the switch-a-roo token if you think it may conflict with your needle in teh haystack.
## HOMEBREW str_ireplace() FOR PRE-PHP 5.0
if (!function_exists('str_ireplace') {
function str_ireplace($search,$replace,$subject) {
$token = '^[[term^]';
$haystack = strtolower($subject);
$needle = strtolower($search);
while (($pos=strpos($haystack,$needle))!==FALSE) {
$c++;
$subject = substr_replace($subject,$token,$pos,strlen($search));
$haystack = substr_replace($haystack,$token,$pos,strlen($search));
}
while (($pos=strpos($subject,$token))!==FALSE) {
$subject = substr_replace($subject,$replace,$pos,strlen($token));
}
return $subject;
}
}

There appears to be a "bug" with this function in at least version 5.2.1.
If you attempt to use the function while replacing special characters, such as new lines, it will cause your entire scripts to fail. It resulted in my browser (Firefox 2) trying to download the file instead of parsing it.
Here is example code which will cause problems:
<?php
$sometext = "this is some text\n";
$sometext .= "that has a new line in it";
echo break_lines($sometext);
function break_lines ($text)
{
return str_ireplace("\n", "<br/>", $text);
}
?>
However, if you simply get rid of the "i" and use the normal str_replace, the page will load just fine.
I have also tried the same code on 5.2.3 and this version does NOT have the same problem, so it does appear to be an issue that was resolved with the newest builds of php.
I don't think it was a result of my personal environment, but I am running Debian-Sarge, Apache 2 and PHP 5.2.1/5.2.3.

Yet another one str_ireplace ireplacement, this one will take arrays as $search and $replace
<?php
function make_pattern(&$pat, $key) {
$pat = '/'.preg_quote($pat, '/').'/i';
}
if(!function_exists('str_ireplace')){
function str_ireplace($search, $replace, $subject){
if(is_array($search)){
array_walk($search, 'make_pattern');
}
else{
$search = '/'.preg_quote($search, '/').'/i';
}
return preg_replace($search, $replace, $subject);
}
}
?>

str_ireplace for php below version 5. :)
if(!function_exists('str_ireplace')) {
function str_ireplace($search,$replace,$subject) {
$search = preg_quote($search, "/");
return preg_replace("/".$search."/i", $replace, $subject); } }

Note that character case is being defined by your server's locale setting, which effects strings containing non-ASCII characters.
See strtolower() - http://www.php.net/strtolower and comments - internally str_ireplace converts $search and $replace to lowercase to find matches.

This functionality is now implemented in the PEAR package PHP_Compat.
More information about using this function without upgrading your version of PHP can be found on the below link:
