Try using the super global $_FILES. There are a couple of better whys
to copy files in php other than directly from $_POST. After a post,
files are automatically saved in a temporary location, and all you have
to do is copy/rename them to where you want.
Its in the manual somewhere, i can't recall where exactly though,
probably in the section about file upload handling or superglobals.
