PHP Trying to find a spefic line in text file and echo it

Question

So I am trying to find a list of steam ID's in a scraped html file. This is what I have so far but it's not working, it is parsing an html page I saved as text and supposed to be outputting things with below variables and it is outputting a blank page.

   <?php
$filein = file('TF2U.txt');
foreach ($filein as $html) {
    $pattern = '#.*<a[^>]+href="steamcommunity.com/profiles/([0-9]+)/"#iA';
    $matches = NULL;
    $match_count = preg_match_all($pattern, $html, $matches);
    if ($match_count > 0) {
        echo implode($matches[1]);
        echo "<br>\n";
        }
}
?>

Any help would be awesome, I am not sure what I am missing but it's probably simple.

if someone could post an example that would help, that link you posted had WAY too many random examples that none of which seem to do what I need, though maybe I am not sure what it is doing. — SuperMar1o, Apr 20 '13 at 16:11
Replace `.*]+href="steamcommunity.com/profiles/([0-9]+)/"` with `]+"`, if it doesn't work, can you provide a "sample" of what's in TF2U.txt ? Because I think you could do it with a single preg_ function. — HamZa, Apr 20 '13 at 17:19
did not seem to work. I tried posting the file to pastebin but here it was too large so here is the original file. http://rghost.net/45431914. All I want essentially is a list of the numbers after the /profiles/ in a vertical line if it's simpler to do that — SuperMar1o, Apr 20 '13 at 17:29
`$file = file_get_contents('TF2U.htm'); preg_match_all('#\d+)[^>]+#msi', $file, $matches); print_r($matches['id']);` Enjoy, and don't do evil things with it :) — HamZa, Apr 20 '13 at 17:40
would you mind making that an answer so I can give you credit? =) — SuperMar1o, Apr 20 '13 at 18:00

The problem is that the links aren't ending with a /, so here's a solution with some tweaks:

$file = file_get_contents('TF2U.htm');
preg_match_all('#<a.*?href="(?:http://)steamcommunity.com/profiles/(?P<id>\d+)[^‌>]+#msi', $file, $matches);
print_r($matches['id']);

Worked like a charm, was able to use this to parse all 100,000 lines =) Thanks a ton! – SuperMar1o Apr 21 '13 at 00:23
