<?php // http://php.net/manual/en/language.oop5.typehinting.php says that type-hinted PHP parameter // that has no default value set to null can't be null. But are you sure? // First, some magic! function custom_error_handler($level, $message, $file = '', $line = 0, $context = array()) { if (error_reporting() & $level) { throw new Exception($message, 0, $level, $file, $line); } } set_error_handler('custom_error_handler'); error_reporting(0); // Yeah, not the best solution class SomeClass {} function test(SomeClass $instance) {var_dump($instance);} // NOTE: E_RECOVERABLE_ERROR (4096) occurs here test(null); // But what is this?! We have NULL in output! Are you surprised?

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
