run code in 200+ php & hhvm versions
Bugs & Features
<?php class Devzone { public $about = 'PHP7'; public $performance = 'How well does PHP 7 perform?'; } $devzone = new Devzone(); echo $devzone->about . "\n"; echo $devzone->performance . "\n"; echo PHP_VERSION . "\n";

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
