Question

So I’m trying to get the id from a url for youtube..

here is the url

http://gdata.youtube.com/feeds/api/videos/kffacxfA7G4/related?v=2

then there’s also – in the url too.

it wouldn’t let me post another url but it’s the same as above but with the id ucvkO0x-mL4

how can I grab between videos/ and /related (the id) with regex?

I tried to use txt2re.com which is what I always use, but it’s not working for this case..

thanks!

No need for even regex, just a simple strpos and substr will do it. Or just use explode like this:

<?php

$url = 'http://gdata.youtube.com/feeds/api/videos/kffacxfA7G4/related?v=2';

//BY STRPOS/SUBSTR
echo substr($url, 42, strpos($url, '/related', 42) - 42);

//BY EXPLODE
$parts = explode('/', $url);
echo $parts[6];
?>
