run code in 300+ PHP versions simultaneously
<?php class myclass{ public static $i = 0; public function one($called_from = null){ if ( $called_from != 'two'){ return $this->two(); } self::$i += 1; echo self::$i.PHP_EOL; } public function two(){ return $this->one(__FUNCTION__); } } $obj = new myclass; $obj->one();

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).
