uploading huge files via http is pretty hit or miss. IME, if you keep the files to <= 500k, you shouldn't have trouble. Anything over that gets dicey as the file size increases. The webserver is more likely than not to time out. Try into ftp or fsockopen().

<?php
$host = 'www.example.com';
$port = 80;

$fp = fsockopen($host, $port, &$err_no, &$err_msg, 10)
    or die ("Could not open a socket connection to host <i>$host</i> on port <i>$port</i>.
        The error message returned was '<i>$err_msg</i>'.");

echo "A socket connection to host <i>$host</i> on port <i>$port</i> was successfully opened."
?>
