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/>";
   }
}
?>
