<?php $items = [ 'a' => [], 'b' => ['id' => 'B'], 'c' => ['id' => 'C'], 'd' => [], 'e' => ['id' => 'E'], ]; var_export( array_filter( array_combine( array_keys($items), array_column($items, 'id'))));

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).
