title: Use preg_* to do time()
body: <p>I'm kinda stuck here, I made some preg coding to find any 11 digits numbers, but what I don't know how to make it use the found/matched to a function like "preg - time()"</p>
  
  <p>Reminder, the 11 digits will might be found more than one time, so the function should be enable to be used on any of them, maybe a loop on a array or anything?</p>
  
  <pre><code>"#\d{11}#"   -   Quick example on the preg i might will use.
  </code></pre>
  
  <p>Help!</p>
