<?php $row = ['Rick', 'Lewi', 'Ferdi', 'Stefan']; $mapping = ['Team1', 'Team2', 'Team3']; $mappingCount = count($mapping); $row = array_merge(array_fill(0, $mappingCount, null), $row); var_dump($row);

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).
