Errors not being caught by "try" block [duplicate]

Question

I was expecting this page to render as the string "TryErrorFinally", but the result is just the string "Try". Do I need to do something else to see the exception generated by calling the non-existent foo() function?

<?php
  try {
    print "Try";
    foo();
  } catch (Exception $e) {
    print "Error";
  } finally {
    print "Finally";
  }
?>
