run code in 200+ php & hhvm versions
Bugs & Features
<?php function foo() { static $bar = "1234567890123456789012345678901234567890"; return $bar; } var_dump(memory_get_usage()); foo(); var_dump(memory_get_usage());

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.
