If you have multiple file upload fields named "files[]"...



<?php

if (isset($_FILES["files"])) {

   $uploads = new MultipleIterator(MultipleIterator::MIT_KEYS_ASSOC);

   $uploads->attachIterator(new ArrayIterator((array) $_FILES["files"]["name"]), "name");

   $uploads->attachIterator(new ArrayIterator((array) $_FILES["files"]["size"]), "size");

   $uploads->attachIterator(new ArrayIterator((array) $_FILES["files"]["type"]), "type");

   $uploads->attachIterator(new ArrayIterator((array) $_FILES["files"]["tmp_name"]), "tmp_name");

   $uploads->attachIterator(new ArrayIterator((array) $_FILES["files"]["error"]), "error");



   foreach ($uploads as $file) {

      echo htmlspecialchars($file["name"]) . " = {$file["size"]} bytes<br/>";

   }

}

?>
