title: javascript/jquery : extract phone numbers from string
body: <p>I'm trying to extract phone number from a string which can be empty or look like one of the following examples:</p>
  
  <ul>
  <li>"Tél. : 04 27 52 12 87 Port. : 07 67 11 06 87"</li>
  <li>"Tél. : 04 27 52 12 87"</li>
  <li>"Port. : 07 67 11 06 87"</li>
  </ul>
  
  <p>In addition, a phone number could look like this: (0039) 234786
  So the constant(s) are "Tél. :" and/or "Port. :"</p>
  
  <p>The have put these numbers in two variables (cell &amp; landline).</p>
  
  <p>I've tried split and indexOf functions but I'm pretty sure that there's a better and more efficient way to do this. </p>
  
  <p>Any ideas ?</p>
