run code in 300+ PHP versions simultaneously
<?php $array = [ [ 'a' => 1, 'b' => 2, 'c' => 3], [ 'a' => 4, 'b' => 5, 'c' => 6], [ 'a' => 7, 'b' => 8, 'c' => 9] ]; foreach ($array as $key => $val) { unset($array[$key]['a']); } reset($array); foreach ($array as $key => $val) { echo $key . ' => ' . $val['b'] . ', ' . $val['c'] . PHP_EOL; }

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).
