run code in 300+ PHP versions simultaneously
<?php class TestClass { public function baz() { echo "Worked!"; } } $foo = 'bam'; $bam = ['bar' => new TestClass()]; var_dump($$foo); var_dump($$foo['bar']); $$foo['bar']->baz(); // function getResult() { // return "string"; // } // echo getResult(){0};

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).
