regex help

hi
i have this link:

http://forum.te3p.com/314972.html

Code (markup):

i need to get the number before .html extension.
so my regex pattern should get only the number..
here is my code:

$url = 'http://forum.te3p.com/';
	$pattern_url = str_replace('/',"\/",$url);
	$pattern_url = str_replace('.',"\.",$pattern_url);

if(preg_match_all("/$pattern_url([0-9]*?)\.html/", $s, $t))

PHP:

any help would be appreciated...

 

$input = 'http://forum.te3p.com/314972.html';
$url = 'http://forum.te3p.com/';
if (preg_match_all('/' . preg_quote($url, '/') . '([0-9]*)\.html/iU', $input, $matches, PREG_SET_ORDER)) {

}

PHP:

 

Use this:

$url = 'http://forum.te3p.com/314972.html';
preg_match_all('/\/([0-9]+)\./Usm',$url,$results);
print_r($results);

PHP:

 

Why would you not use parse_url, and then just strip off everything else.

$parsed_url = parse_url('http://forum.te3p.com/314972.html');

$numbers = (int)$parsed_url['path'];

Or if there are potentially zero's you could do.

$numbers = substr(1,strpos('.',$parsed_url['path'] -2),$parsed_url['path']);
