2 fonctions valent mieux qu'un long discours !

read_dir

public static function read_dir_recursive($path, $extensions=array("js", "css")
{
||t||if (!is_dir($path))
||t||||t||return false;
||t||||t||
||t||return glob($path.'/*.{'.implode(",",$extensions).'}', GLOB_BRACE);
}

rm_dir

public static function rm_dir_recursive($path)
{
||t||if (!file_exists($path))
    ||t||return false;

||t||return is_file($path) ?
||t||||t||||t||||t||@unlink($path) :
||t||||t||||t||||t||array_map(array('YOUR_CLASS', 'rm_dir_recursive'), glob($path.'/*', GLOB_BRACE)) == @rmdir($path);
}
