<?php $content = <<<'EOF' Line 1 Line 2 EOF; $tmpCsvFile = new SplTempFileObject(); $tmpCsvFile->fwrite($content); $iterator = new CallbackFilterIterator($tmpCsvFile, function ($row) { return true; }); echo 'l1: ', iterator_count(new LimitIterator($iterator, 2)), ' ', iterator_count(new LimitIterator($tmpCsvFile, 2)), "\n"; echo 'l2: ', iterator_count(new LimitIterator($iterator, 3)), ' ', iterator_count(new LimitIterator($tmpCsvFile, 3)), "\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).
