run code in 200+ php & hhvm versions
Bugs & Features
<?php function test($var) { debug_zval_dump($var); //$GLOBALS['a']++; echo $var; } $a = 0; test($a);

Here you find the average performance (time & memory) of each version. A greyed 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.
