run code in 300+ PHP versions simultaneously
<?php $input = ["a" => ["green"], ["red"], "b" => ["green"], ["blue"], ["red"]]; $result = array_unique($input); print_r($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).
