parse youtube video id using preg_match
Grab the video ID only from youtube's URLs

I use something like this now but i get a lot of errors…

$video_id = $_GET['url'];

$video_id = str_replace('http://www.youtube.com/watch?v=','',$video_id);
$video_id = str_replace('&feature=related','',$video_id);
$video_id = str_replace('&feature=fvwrel','',$video_id);
$video_id = str_replace('&hd=1','',$video_id);
$video_id = str_replace('&feature=relmfu','',$video_id);
$video_id = str_replace('&feature=channel_video_title','',$video_id);
$video_id = str_replace('&feature=list_related','',$video_id);
$video_id = str_replace('&playnext=1','',$video_id);
$video_id = str_replace('_player','',$video_id);

The problem is that youtube has multiple url variables for ‘&feature=’ and maybe others

The only thing i want to extract from the youtube url is the unique video id

ex: //www.youtube.com/watch?v=lgT1AidzRWM&feature=related

and nothing after the id or before

can someone help me to get it?

What you can do is this:

$url = "http://www.youtube.com/watch?v=lgT1AidzRWM&feature=related";
$p_url = parse_url($url);
parse_str($p_url['query'], $p_param);
print_r($p_param['v']);
