run code in 300+ PHP versions simultaneously
<?php null->test ?? "test"; isset(null->test) ?: "test"; null->test->call() ?? "test"; empty(null->test->call()) ?: "test";

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).
