run code in 300+ PHP versions simultaneously
<?php $ids = [1, 1, 1, 2, 5, 1]; $sizes = ["m", "m", "m", "s", "xl", "s"]; $colors = ["red", "red", "yellow", "orange", "red", "orange"]; foreach ($ids as $i => $id) { $size = $sizes[$i]; $color = $colors[$i]; $tempKey = "{$id}:{$size}:{$color}"; if (!isset($result[$tempKey])) { $result[$tempKey] = [ 'id' => $id, 'size' => $size, 'color' => $color, 'stock' => 1 ]; } else { ++$result[$tempKey]['stock']; } } var_export(array_values($result));

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).
