如何使用PHP将URL重定向到YouTube？

Question

我面临的问题

• 当我们检索说明http://youtu.be/YFZ2L0sNzvM?a的网址被重定向时。

• 当我在浏览器上复制粘贴此网址时，我们会检索错误的网址http://t.co/hNLWmspb，并重定向https://www.youtube.com/watch?v=XzqagJTsNrc&feature=youtu.be。

• 所以我检索了http://t.co/hNLWmspb，以便如何将链接重定向到您的网址。

此行中的错误

           /* bug in this line */
         /* $media_url = 'http://t.co/hNLWmspb' */
           /**  how to solve this issue when url is retrive that is not you redirection url.*/

            <a href='.$media_url.' class="html5lightbox" data-group=""
              titl="'.$tweet_content.'">';
