Halloween Contest - Caeser Cipher

[Artificial]

Ignoring the fact that nobody (including myself since I omitted the greek/latin substitution) addresses the actual problem, everyone just shifts the character by 3 according to their ASCII value. gameCHIEFs goes one step further by checking the alphanumeric value prior to the encryption/decryption (which is silly, as z will be encrypted to a special char and then it will be unable to be decrypted), all of which can be rewritten as something as small as:

 function crypt($str, $offset) { return implode('', array_map(function($c) { return preg_match('/[a-z]/i', $c) ? chr(ord($c) + $offset) : $c; }, str_split($str))) }
function encrypt($str) { return crypt($str, 3); }
function decrypt($str) { return crypt($str, -3); } 
  

Anything which produces special chars should be an automatic fail.
You all suck at programming. Get gud.

No it doesn't. It starts back over at the beginning of the string. loc = loc % chars.length;
