run code in 200+ php & hhvm versions
<?php echo "---------------------password check----------------------- \n"; $str1="JamesBlunt32"; if(preg_match("/\A(?=\w{6,12}\z)(?=[^a-z]*[a-z])(?:[^A-Z]*[A-Z])(\D*\d.*)\z/", $str1)==1){ echo "Password valid \n"; } else echo "Password invalid \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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
