PHP sucks

catch_me.php

<?php

namespace x;
require 'catch_me2.php';
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 1);

try {
	\y\shittyCode();
}
catch (Exception $e) {
	echo 'Gotcha!';
}

//Guess what? Uncaught exception 'Exception' with message 'catch me if you can' :)
//No error caused by lack of Exception class in this namespace

catch_me2.php

<?php

namespace y;

function shittyCode() {
	throw new \Exception('catch me if you can');
}

You are throwing \Exception which is base exception class from PHP standard library. You're catching Exception from namespace x. Replace Exception with \Exception in catch_me.php at line 11 and everything works as it should.

And please change snippet name to "Reinmar can't read manual." :P

I know what's the difference between \Exception and Exception, and already fixed that in my script. But the problem is with lack of information - there's silent failure, although in namespace x there's no Exception class.

You can show that without second file - that was suggesting something different. Just throw new \Exception and works the same. But you're right, there's no info about not defined exception class, and I agree it should be one. It's mentioned in manual.

I know I can, but then it wouldn't be so tricky :> In the case I was working on the exception was thrown far far away, so it took me a while before I've found wtf.
