PHP error to exception converter with special invalid argument handling

gistfile1.php

<?php
//This converts errors into exceptions, but if the error is caused 
//by an argument being invalid (for example failing a typehint), it gets converted into an InvalidArgumentException
function handle($code, $message, $file, $line) {
    //This test might be naive but it worked in my very very simple test code :)
    if(strpos($message, 'Argument ') === 0) {
        throw new InvalidArgumentException($message);
    }
    else {
        throw new ErrorException($message, 0, $code, $file, $line);
    }
}

set_error_handler('handle');
