Actually the else clause is not necessary.  That's one of the nice things 
about exceptions.  If you throw an exception, processing jumps to the 
appropriate catch and never returns.  

try {
  // Do normal stuff.

  if (!$valid) {
throw new Exception('OMG!');
  }

  // Do more normal stuff.
}
catch (Exception $e) {
  // Print user friendly message.
  // Log detailed information or whatever you're going to do.
}

Lars,

Here's a pseudo code:

try {
  if (!$valid) {
throw new Exception("Test failed.");
  } else {
   // do something
  }
} catch (Exception $e) {
  // set/print a user friendly message to send to output

  // set a detailed message using debug_backtrace() or any other information 
relevant for easier troubleshooting
  // log and/or email detailed message
}

Regards,
Tommy
