run code in 200+ php & hhvm versions
Bugs & Features
<?php $pf = array( 'a' => 1, 'b' => 2 ); print_r ($pf['a']); print_r( $pf); ?>

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.
