// I needed to empty a directory, but keeping it
// so I slightly modified the contribution from

// A short but powerfull recursive function
// that works also if the dirs contain hidden files
//
// $dir = the target directory
// $DeleteMe = if true delete also $dir, if false leave it alone

function SureRemoveDir($dir, $DeleteMe) {
if(!$dh = @opendir($dir)) return;
while (false !== ($obj = readdir($dh))) {
if($obj==’.’ || $obj==’..’) continue;
if (!@unlink($dir.’/’.$obj)) SureRemoveDir($dir.’/’.$obj, true);
}

closedir($dh);
if ($DeleteMe){
@rmdir($dir);
}
}

//SureRemoveDir(‘EmptyMe’, false);
//SureRemoveDir(‘RemoveMe’, true);
