php - 服务器端的 Youtube 下载器脚本

Question

我正在尝试生成一个可以在服务器上下载 youtube 视频的脚本，我希望用户提供视频 url。

我搜索了很多，但无法使其工作。这是我的代码。

    <?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{');
?>

但我仍然坚持这一点，请帮助我。
