[RESOLVED] RegEx Problem for youtube links

this is what I have so far:

[code=html]/(http://www.youtube.com/watch?v=[a-zA-Z0-9]+)/[/code]

which gets [url]http://www.youtube.com?v=abcABC123[/url]

but if the link is [url]http://www.youtube.com/watch?v=abcABC123&feature=related[/url], it does not include &feature=related

this is the full code I am using it in:

[code=php]
function youtubeRender($uri) {

return “<a href=’$uri’>$uri</a>”;
}

function getYoutubeLink($string){
$regex = “/(http://www.youtube.com/watch?v=[a-zA-Z0-9]+)/”;
$string = preg_replace_callback($regex, create_function(‘$matches’, ‘return youtubeRender($matches[0]);’), $string);
return $string;
}

// this link work OK
echo getYoutubeLink(“http://www.youtube.com/watch?v=abcABC123 this video is cool”);

// this link doesn’t include “&feature=related” into the rendered link
echo getYoutubeLink(“http://www.youtube.com/watch?v=abcABC123&feature=related this video is cool”);
[/code]

I haven’t really used Regular Expressions much, so If anyone with more knowledge than me can get it working, It would be much appreciated ?

Thanks

Also in #PHP _↴
