run code in 300+ PHP versions simultaneously
<?php $time = mktime(23, 59, 59, 09, 06, 2013); $format1 = "%I:%M %p"; $format2 = "%I:%M %P"; assert(strftime($format1, $time) === '11:59 PM'); // as documented on php.net/strftime, %p => PM assert(strftime($format2, $time) === '11:59 pm'); // and %P => pm assert(strptime($format1, '11:59 PM') !== false); assert(strptime($format2, '11:59 pm') !== false);

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).
