Extracting specific information out of string

I have a string that contains an address to a youtube video, I want to use this to display the video in a pop-up lightbox. In the current form the link will not work in the lightbox:

http://www.youtube.com/v/CD2LRROpph0?f=videos&c=TEST&app=youtube_gdata&version=3

I has an idea to extract the video id 'CD2LRROpph0' and just append that to a regular youtube url, for example 

http://www.youtube.com/watch?v=CD2LRROpph0.

Which i know works in the lightbox.

Any ideas on how to extract this code from the string???

This one will handle different protocols and different YouTube URLs (in case YouTube come out with country specific TLDs, for example).

$urlTokens = parse_url($url);

$newUrl = $urlTokens['scheme'] . '://' . $urlTokens['host'] . '/watch?v=' . preg_replace('~^/v/~', '', $urlTokens['path']);

Or try this, you get an array back and can use the query you want http://www.php.net/manual/en/function.parse-url.php

$newUrl = preg_replace('@http://www.youtube.com/v/([a-z0-9_\-]{11}).*$@i', 
   'http://www.youtube.com/watch?v=$1', $string);
