Is there any way to extract a YouTube video ID from url?

darkus

If a URL is inputted into my code like this for example:

http://www.youtube.com/watch?v=7KdMiRUbHi0&feature=channel

Does anyone know a way to code a system to pull out the video ID so my result would be this:

7KdMiRUbHi0

Bascly to pull out all the characters after the v= and before the & or any other characters?

thanks for any tips or help!

someone will post a preg_replace() pattern, but this will work

$string = "http://www.youtube.com/watch?v=7KdMiRUbHi0&feature=channel";
$url = parse_url($string);
parse_str($url['query']);
echo $v; //7KdMiRUbHi0

Oh thats awesome, thanks man, much appreciated!!

I actually have a little bit more complicated follow-up question for anyone who can figure it out.

I have a $textarea which would contain a string such as:

text text text text text text text text text text text text text text text text text text http://www.youtube.com/watch?v=7KdMiRUbHi0&feature=channel text text text text text text text text text text text text text text text text text text

and I would like to try to build a php routine that would change that $textarea to now be

text text text text text text text text text text text text text text text text text text [youtube]7KdMiRUbHi0l[/youtube] text text text text text text text text text text text text text text text text text text

So using your method I was able to extract out the 7KdMiRUbHi0l and then I can add [youtube] and [/youtube] around it.

But Im having trouble writing a routing that will actualy search out the [URL="... from my $textarea and replace it with my new content. The biggest problem for me is telling it where to end in terms of the [/URL].

I know this is a bit involved, but i'm hoping someone out there can think of a good solution to this.

thanks!
