run code in 300+ PHP versions simultaneously
<?php $a = ['0' => 1, '1' => 2, '2' => 3]; $b = ['0' => 4, '1' => 5, '2' => 6]; $newArray = array_map('combine',array_map(null, $a, $b)); function combine($n){ return array_combine(array('a','b'),$n); } print_r($newArray);

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).
