PHP-Batch: Chmod alle JPGs eines Ordners

[Janosch]

Hier meine directory funktion:

function directory($dir,$filters){
 $handle=opendir($dir);
 $files=array();
 if ($filters == "all"){while(($file = readdir($handle))!==false){$files[] = $file;}}
 if ($filters != "all"){
  $filters=explode(",",$filters);
  while (($file = readdir($handle))!==false) {
   for ($f=0;$f<sizeof($filters);$f++):
    $system=explode(".",$file);
    if ($system[1] == $filters[$f]){$files[] = $file;}
   endfor;
  }
 }
 closedir($handle);
 return $files;
}
