Has anyone got any experience parsing the video id from youtube urls in php.

ie.
youtube.com/watch?v=R0BA-KviNO4&feature=related

Where the red is the part I want.

actually judging on your selfmade cms ...

I'll assume php ?

Code:

$string = "youtube.com/watch?v=R0BA-KviNO4&feature=related";

preg_match('/v\=(.+)&/',$string,$matches);

echo $matches[1];

do a semi ok job for you ?

I just cracked it without regular expressions from a little googling.

Here is the code it allows you to enter the url of a youtube vid in to a form and the code processes the form to parse the video id and insert it in to an embed code with preset values.

PHP Code:

  //parse the id from the url
$url = $_POST['id'];
$vidparser = parse_url($url);
parse_str($vidparser[query], $query);
$vidid = ($query['v']);
 
 
//get the video id in to the embed code
$content = "<object width=\"290\" height=\"235\"><param name=\"movie\" value=\"http://www.youtube.com/v/".$vidid."&hl=en&fs=1&rel=0\"></param><param name=\"allowFullScreen\" value=\"true\"></param><embed src=\"http://www.youtube.com/v/".$vidid."&hl=en&fs=1&rel=0\" type=\"application/x-shockwave-flash\" allowfullscreen=\"true\" width=\"290\" height=\"235\"></embed></object>";

seems to work well! I wrote it to a text file for include..

cheers for your help..

ah fair enough I'd assumed it'd be part of a multiline post or something similar not just a URL you had
