<?php class MyCustomError extends Error {} function doStuff() { try { throw new InvalidArgumentError("You are doing it wrong!", 112); } catch(Error $e) { throw new MyCustomError("Something happened", 911, $e); } } try { doStuff(); } catch(Error $e) { do { printf("%s:%d %s (%d) [%s]\n", $e->getFile(), $e->getLine(), $e->getMessage(), $e->getCode(), get_class($e)); } while($e = $e->getPrevious()); } ?>
