run code in 300+ PHP versions simultaneously
<?php $txt = <<<TXT 1 Hello! 2 How 3 are 4 you? TXT; $file = new SplFileObject('php://memory', 'w+'); $file->fwrite($txt); echo 'Seeking line 1...', PHP_EOL; $file->seek(0); echo 'Position in the file: ', $file->ftell(), PHP_EOL; echo 'Rest of the file: ', PHP_EOL, $file->fread(5000); echo PHP_EOL, '-------------', PHP_EOL; echo 'Seeking line 2...', PHP_EOL; $file->seek(1); echo 'Position in the file: ', $file->ftell(), PHP_EOL; echo 'Rest of the file: ', PHP_EOL, $file->fread(5000);

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).
