You can use this to quickly find all the files (recursively) in a certain directory. This beats maintaining a stack yourself.
<?php
$directory = "/tmp/";
$fileSPLObjects = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($directory),
RecursiveIteratorIterator::CHILD_FIRST
);
try {
foreach( $fileSPLObjects as $fullFileName => $fileSPLObject ) {
print $fullFileName . " " . $fileSPLObject->getFilename() . "\n";
}
}
catch (UnexpectedValueException $e) {
printf("Directory [%s] contained a directory we can not recurse into", $directory);
}
?>
Note: if there is a directory contained within the directory you are searching in that you have no access to read an UnexpectedValueException will be thrown (leaving you with an empty list).
Note: objects returned are SPLFileObjects

Recursive multidimensional array flatten using SPL
<?php
function array_flatten_recursive($array) {
if($array) {
$flat = array();
foreach(new RecursiveIteratorIterator(new RecursiveArrayIterator($array), RecursiveIteratorIterator::SELF_FIRST) as $key=>$value) {
if(!is_array($value)) {
$flat[] = $value;
}
}
return $flat;
} else {
return false;
}
}
$array = array(
'A' => array('B' => array( 1, 2, 3, 4, 5)),
'C' => array( 6,7,8,9)
);
print_r(array_flatten_recursive($array));
?>
-- Returns:
Array (
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
[6] => 7
[7] => 8
[8] => 9
