<?php function uppercase(Traversable $in) { foreach ($in as $word) { yield strtoupper($word); } } function reverse(Traversable $in) { foreach ($in as $word) { yield strrev($word); } } function each_println(Traversable $in) { foreach ($in as $line) { echo "$line\n"; } } $words = new ArrayIterator(["foo", "bar", "baz"]); each_println(reverse(uppercase($words)));

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).
