Youtube downloader script on server end - php

Question

I am trying to generate a script which can download youtube videos on the server, I would like the user to provide the video url.
I have searched a lot but, could not make it work. Here's my code.
<?php
// Check download token
if (empty($_GET['mime']) OR empty($_GET['token']))
{
exit('Invalid download token 8{');
}
// Set operation params
$mime = filter_var($_GET['mime']);
$ext = str_replace(array('/', 'x-'), '', strstr($mime, '/'));
$url = base64_decode(filter_var($_GET['token']));
$name = urldecode($_GET['title']). '.' .$ext;
// Fetch and serve
if ($url)
{
// Generate the server headers
if (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== FALSE)
{/*
header('Content-Type: "' . $mime . '"');
header('Content-Disposition: attachment; filename="' . $name . '"');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header("Content-Transfer-Encoding: binary");
header('Pragma: public');
*/}
else
{/*
header('Content-Type: "' . $mime . '"');
header('Content-Disposition: attachment; filename="' . $name . '"');
header("Content-Transfer-Encoding: binary");
header('Expires: 0');
header('Pragma: no-cache');
*/}
$download_video_file = file_put_contents($file_path, fopen($url, 'r'));
exit;
}
// Not found
exit('File not found 8{');
?>
But I am still stuck at this, Please help me out.

You will get the code from here
Ref : https://code.google.com/p/php-youtube-downloader/
<?php
require_once('youtube.lib.php');
$download_link = get_youtube('http://www.youtube.com/watch?v=SAQZ0BDXn48');
// we will have array here, index 0 is the video ID and index 1 is the download link.
echo $download_link[1];
?>
