This is an alternative to the function i have posted yesterday
(http://www.php.net/manual/en/function.rmdir.php#99838: a function to remove a folder content and
sub content, without delete the main folder).
This solution use scandir instead of readdir.
This avoid problems with folders named "0" (ok... why rename a folder 0?? I don't
know but is what the "phpthumb" script does when it caches and stores the images :D)
<?php
/* Example:
full_emptydir( array( 'dirname' => 'yourpath', 'preserve' =>
array('keepme.html') ) );
*/
function full_emptydir($fields){
if( !isset($fields['dirname']) or( isset($fields['dirname']) and
!@scandir($fields['dirname']) )) return;
$dirname = $fields['dirname'];
$DeleteMe = isset($fields['DeleteMe']) ? $fields['DeleteMe'] : false;
$preserve = isset($fields['preserve']) ? ( is_array($fields['preserve']) ?
$fields['preserve'] : array() ) : array();
if(is_array(scandir($dirname))){
$obj = scandir($dirname);
foreach($obj as $value){
if($value == '.' or $value == '..') continue;
if( count($preserve) == 0 or (count($preserve) > 0 and !in_array($value, $preserve) ) ){
if (!@unlink($dirname.'/'.$value)) full_emptydir( array( 'dirname' =>
$dirname.'/'.$value, 'DeleteMe' => true, 'preserve' =>
$preserve) );
}
}
}
if ($DeleteMe){
@rmdir($dirname);
}
}
?>
Thank you Gabriel, my friend, for the "scandir" hint ;)
