title: What is the exit code after a php exception?
body: <p>I'm working with a program that runs a command-line PHP script. The PHP script has been throwing exceptions, but the program has been seeing exit code 0 (and not checking for exceptions).</p>
  
  <ul>
  <li>Do PHP scripts actually return a different exit code and the program is just getting the wrong exit code somehow?</li>
  <li>Or do they really return exit code 0 with an exception?</li>
  <li>Or do they not return an exit code at all?</li>
  </ul>
