class.upload.php is a powerful and mature PHP class to manage uploaded files, and manipulate images in many ways. The script is available under a GPL license.
more info about the class
$upload = new Upload($_FILES['photos']); var_dump($_FILES['photos']); // It is all filedata here. All ok! var_dump($upload->uploaded); // null
Your upload.class is amazing.
But for what reason this happens?
