run code in 300+ PHP versions simultaneously
<?php method_exists('SplFileObject', 'fread') or die("No SplFileObject::fread()"); $i=0; $file = new SplFileObject('/path/to/a/file.txt'); while ($i++ < 1000 && ($chunk = $file->fread($file->getSize()) !== false) { echo $chunk . "\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).
