Sometimes you would face situations in which rmdir($dirname) would give "permission denied" errors though you may have changed $dirname permissions. In such situations just change the permissions of the directory which contains $dirname and rmdir($dirname) would work like a charm.
Say you use rmdir('dirr'); then change the permissions of the folder that contains 'dirr'.

I had situation where the rmdir was returning warning message as within last loop it was already removed. So here is quick fix by adding is_dir to the DelTree routine below
<?php
function delTree($dir) {
$files = glob( $dir . '*', GLOB_MARK );
foreach( $files as $file ){
if( substr( $file, -1 ) == '/' )
delTree( $file );
else
unlink( $file );
}
if (is_dir($dir)) rmdir( $dir );
}
?>

I wasn't having much luck with the recursive delete functions below, so I wrote my own:
<?php
// ensure $dir ends with a slash
function delTree($dir) {
$files = glob( $dir . '*', GLOB_MARK );
foreach( $files as $file ){
if( substr( $file, -1 ) == '/' )
delTree( $file );
else
unlink( $file );
}
rmdir( $dir );
}
?>
Simple. Works.

A patch to previous script to make sure rights for deletion is set:
<?php
//Delete folder function
function deleteDirectory($dir) {
if (!file_exists($dir)) return true;
if (!is_dir($dir) || is_link($dir)) return unlink($dir);
foreach (scandir($dir) as $item) {
if ($item == '.' || $item == '..') continue;
if (!deleteDirectory($dir . "/" . $item)) {
chmod($dir . "/" . $item, 0777);
if (!deleteDirectory($dir . "/" . $item)) return false;
};
}
return rmdir($dir);
}
?>

Here's another version of the recursive directory removal. This version requires PHP 5, and returns TRUE on success or FALSE on failure.
<?php
function deleteDirectory($dir) {
if (!file_exists($dir)) return true;
if (!is_dir($dir)) return unlink($dir);
foreach (scandir($dir) as $item) {
if ($item == '.' || $item == '..') continue;
if (!deleteDirectory($dir.DIRECTORY_SEPARATOR.$item)) return false;
}
return rmdir($dir);
}
?>

This function deletes a folder and all it's subfolders and files.
<?php
function remove_dir($current_dir) {
if($dir = @opendir($current_dir)) {
while (($f = readdir($dir)) !== false) {
if($f > '0' and filetype($current_dir.$f) == "file") {
unlink($current_dir.$f);
} elseif($f > '0' and filetype($current_dir.$f) == "dir") {
remove_dir($current_dir.$f."\\");
}
}
closedir($dir);
rmdir($current_dir);
}
}
?>
Might need some improvement, but it works fine.

if you opened a dir with opendir() you must closedir() before try to execute rmdir() or you will get a "permision denied" error on windows systems.
Wrong:
<?php
$handle = opendir($dirpath);
//do whatever you need
rmdir($dirpath);
?>
Right:
<?php
$handle = opendir($dirpath);
//do whatever you need
closedir($handle)
rmdir($dirpath);
?>

In case you're trying to rmdir() and you keep getting 'Permission denied' errors, make sure you don't have the directory still open after using opendir(). Especially when writing recursive functions for deleting directories, make sure you have closedir() BEFORE rmdir().

I've noticed that when using this command on a windows platform you may encounter a permissions error which may seem unwarranted. This commonly occurs if you are or were using a program to edit something in the to be deleted folder and either the item is still in the folder or the program that was accessing the file in that folder is still running(causing it to hold onto the folder).
SO... if you get a permissions error and there shouldn't be an issue with folder permissions check if there are files in there then check if there is a program running that is or was using a file that was in that folder and kill it.

Save some time, if you want to clean a directory or delete it and you're on windows.
Use This:
chdir ($file_system_path);
exec ("del *.* /s /q");
You can use other DEL syntax, or any other shell util.
You may have to allow the service to interact with the desktop, as that's my current setting and I'm not changing it to test this.

If you want to delete a file, or an entire folder (including the contents), use the below function.
