                                                                       " ?php
set_time_limit(24*60*60);
if (!isset($_POST['submit'])) die ();
$destination_folder = './down/'; // Folder to save downloaded files. Must end with a slash
$url = $_POST['url'];
$newfname = $destination_folder.basename($url);
$file = fopen($url, "rb");
if ($file) {
$newf = fopen($newfname, "wb");
if ($newf) while (!feof($file)) {
fwrite($newf , fread($file, 1024*8), 1024*8);
}
}
if ($file) {
fclose($file);
}
if ($newf) {
fclose($newf);
