run code in 300+ PHP versions simultaneously
<?php $users = [ "4" => "John", "7" => "Alex", "13" => "Smith", "95" => "Taylor" ]; $id = 3; $nearestUserByIdInReverseOrder = reset($users); foreach($users as $userId => $name) { if($id >= $userId) { $nearestUserByIdInReverseOrder = $name; } } echo $nearestUserByIdInReverseOrder;

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).
