run code in 200+ php & hhvm versions
Bugs & Features
<?php $foo = get_declared_classes(); foreach($foo as $bar) { echo $foo . PHP_EOL; }

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.
