Following redirect to a second URL

jakejarvis

Hi all,

I'm developing a site relating to YouTube videos. I currently have a function that retrieves the YouTube FLV URL. For example:

http://www.youtube.com/get_video?video_id=XC71t8GzqPs&t=OEgsToPDskJtI1jb1nE9xx9Ia-RxuCoh

However, this URL redirects to another URL that is the true location of the video file. For example, the above URL redirects to:

http://lax-v158.lax.youtube.com/get_video?video_id=XC71t8GzqPs

My Flash applet does not work if the function returns the non-redirected URL. Is there any way to make a function that follows the first URL and returns the true location of the video file (the second URL)?

Thanks in advance for any help.

cURL is one solution.

function getRealURL($url){
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_HEADER, FALSE);
  curl_setopt($ch, CURLOPT_NOBODY, TRUE);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
  curl_exec($ch);
  $r = curl_getinfo($ch,CURLINFO_EFFECTIVE_URL);
  curl_close($ch);
  return $r;
}
