<?php function test() { //It's crucial to construct it in the same line return new class{ static $foo = '-'; }; } $x = test(); $x::$foo = 'x'; $y = test(); $y::$foo = 'y'; var_dump($x::$foo, $y::$foo, ($x === $y), (get_class($x) === get_class($y)));

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).
