closedir

closedir ([ resource $dir_handle ] ) : void

// Open a known directory, read directory into variable and then close
if (is_dir($dir)) {
    if (
$dh opendir($dir)) {
        
$directory readdir($dh);
        
closedir($dh);
    }
}
?>

About deleting a directory after doing a readdir/closedir on it... I'm not sure if this is the solution, but you could try to chdir("/"); before the rmdir to make absolutely sure you aren't standing in the directory (i.e trying to pull out the rug from under yourself).
