title: Extended: what's the finally keyword for?
body: <p>Ok, I understand the "accepted answer" that was given for <a href="https://stackoverflow.com/questions/17292959/whats-the-finally-keyword-for-in-php">this question</a>, but it's still not clear to me what kind of code should I put in finally blocks.</p>
  
  <p>If the use of finally is to get the non-catched exceptions thrown and give a general error message for the system not explode for the user, wouldn't appear two error messages for the user if some exception was catched?</p>
  
  <p>[Edit]</p>
  
  <p>Like @MarkBaker said, the "finally" isn't for catch the uncaught exceptions, the generic catch(Exception $e) do that. So... for what it's useful? Or, in other words, what the finally block does that I can't do after the try/catch blocks without finally?</p>
