Description:
------------
This code should read a directory with all subfolders and files. After that it should delete the whole dir. But it doesnt work. It comes with a lot of permission denied messages. But Files are deletable and with unlink() it works in another test script without the array building. BTW: closedir returns false but I dont know why...

Reproduce code:
---------------
<?php
function readdeldirs($dir)
{
	if($dir[strlen($dir)-1]!='/')$dir.='/';
	$dirs=Array();
	$dh=opendir($dir);
	while(gettype($datei=readdir($dh))!='boolean')
	{
		if($datei!='.' && $datei!='..')
		{
			if(is_dir($dir.$datei))$dirs=array_merge($dirs,readdeldirs($dir.$datei));
			$dirs[]=$dir.$datei;
		}
	}
	
	closedir($dh);
	return $dirs;
}



function deltree($dir)
{
	$load=readdeldirs($dir);
	array_multisort($load, SORT_DESC);
	foreach($load as $del)
	{
		if(is_dir($del))
		{
			rmdir($del);
		}
		if(is_file($del))
		{
			unlink($file);
		}
	}
	rmdir($dir);
}

deltree('download');

Expected result:
----------------
Whole directory with all contents is deleted

Actual result:
--------------
Whole of Permission denied messages
