run code in 300+ PHP versions simultaneously
<?php class foo { const CONSTANT_NAME = 'blah'; } class bar { public $tmp = 'foo'; public function baz() { var_dump( {$this->tmp}::CONSTANT_NAME ); } }

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).
