run code in 200+ php & hhvm versions

<?php var_dump(8/16); var_dump((1/16) * 8); var_dump(pow(16,-1) * 8); var_dump(bcpow('16','-1',1) * 8); var_dump(bcpow('16','-1',4) * 8);

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.
