title: PHP: please help using preg_match
body: <p>Ex: <code>Found: 84 Displaying: 1 - 84</code></p>
  
  <p>I want to get out the number <code>84</code> between <code>Found</code> and <code>Displaying</code> with <code>preg_match</code> but I'm very bad at regular expression.</p>
  
  <p>Do you know what good tutorial to learn regular expression? I can't find a good one on Google.</p>

  <p>I just simplify my problem here. The real problem that I will find it in a full HTML page such as google search. You know what i mean right?</p>
