Above you see the method in action. rand(3,18) is an imitation of the role playing “3d6” (throw 3 sixsided dices). The random generator will give a value between 3 and 18. If you read the rules of Microlite 84 it’s easy to add more character properties.
In this case we’ll save the character data in a cookie in the client browser. However a cookie can only store a string. PHP can convert an array to a string:
Now we can save the data in a cookie via setcookie:
Here is a very short introduction to the principles of PHP. PHP is an acronym for “hypertext preprocessor”. PHP is a serverside language. We use PHP in order to prepare webpages, react to user input – and (on the third semester) to interact with databases.

$e = NULL; // no value set
$f = true; // or false ?>
