<?php class Foo { public $foo = 'foo'; protected $bar = 'two'; private $baz = 'three'; private $for = 4; } $b = (array) new Foo(); var_dump($b["foo"]); var_dump($b["\0*\0bar"]); var_dump($b["\0Foo\for"); var_dump($b["\0Foo\0baz"]);

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).
