<?php // Everything you enter here will be executed by our servers. Try it! function iterator_compose() { foreach (array_reverse(func_get_args()) as $it) { if (is_callable($it)) { $prev = $it; } } } function iterator_chunk($it, $chunkSize) { $chunk = []; $steps = range(0, $chunkSize); while (true) { foreach ($steps as $_) { $chunk[] = $it->current(); $it->next(); if (!$it->valid()) { break 1; } } yield $chunk; $chunk = []; } if ($chunk) { yield $chunk; } } foreach (iterator_chunk(range(0, 125), 32) as $i => $c) { echo "====== Chunk $i ======\n"; var_export($c); echo "\n"; }

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).
