run code in 300+ PHP versions simultaneously
<?php // could be done in one line $str = "a\r\nstring\n"; $str = str_replace(["\r", "\r\n", "\n"], "\n", $str); // PHP_EOL echo $str; ?>

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).
