obtain thumbnail of youtube video

ketanco

hi with a simple form, i get the "a" variable to the url parse file as below.

my goal is to obtain youtube video thumbnails when i enter url. but this doesnt work with some youtube urls for instance such as:

http://www.youtube.com/watch?v=OC2TTslf_YM

the code below doesnt work to obtain youtube thumbnail when i enter this url to the form which send "a" to this file... what modifications should i make in the code below so it works with this url too (and of course still working with the previous urls)

PHP Code:
$regexp = '/v=(-?[a-z0-9]+)/i';
$url=$_POST['a'];

if (preg_match($regexp, $url, $matches)) {
$a = $matches[1];

}
else {
echo 'No match found';
}

$url2='http://img.youtube.com/vi/$id/default.jpg';

$result=str_replace ( '$id' , $a , $url2 );

echo '<img src="'.$result.'" />';

$regexp = '/v=(\-?[a-z0-9]+)/i';

This limits matches to containing only numbers and letters. Try this instead I think:

$regexp = '/v=(\-?[a-z0-9_-]+)/i';
