run code in 300+ PHP versions simultaneously
<?php $format='F j, Y'; for ( $i = 1900; $i < 2050; $i++) { $datep = "$i-01-01"; ?> Trying: <?php echo $datep; ?> = <?php echo date($format, strtotime($datep)); ?><br> <?php } ?>

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).
