title: Regular expressions PHP preg_match_all
body: <p>Hi I am trying to use preg_match_all() to extract the number in bold out of an image URL...</p>
  
  <p><a href="http://profile.ak.fbcdn.net/hprofile-ak-snc4/174844_" rel="nofollow">http://profile.ak.fbcdn.net/hprofile-ak-snc4/174844_</a><strong>39677118233</strong>_8277870_t.jpg</p>
  
  <p>Could someone please help me with the regular expression needed as I am stumped.</p>
  
  <p>I've used this so far:</p>
  
  <pre><code>preg_match_all("(http://profile.ak.fbcdn.net/hprofile-ak-snc4/.*_t.jpg)siU", $this-&gt;html, $matching_data);
  return $matching_data[0];
  }
  </code></pre>
  
  <p>Which is just giving me an array of the full links.</p>
  
  <p>Hope someone can help, thanks!!!</p>
