run code in 300+ PHP versions simultaneously
<?php $arr = [ 'a' => ['e1' => 1, 'e2' => 2, 'e3' => 3], 'b' => ['e4' => 4, 'e5' => 5], 'c' => ['e6' => 6, 'e7' => 7] ]; print_r(array_flip($arr));

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).
