Say you have a checkbox named "box1". When your form is submitted, the PHP script it's submitted to (as specified in <form action="script.php">😉 turns all of your form fields into variables. So the value of box1 would be stored in the variable $box1. Then you can check to see if the value of $box1 is true, meaning it was checked, and you can put the values into your array ("$boxarray = array($box1,$box2,...);"). This is really one of the most basic aspects of PHP and you won't get far without such basic knowledge, so I highly recommend you check out the PHP tutorial (http://www.php.net/tut.php) and the manual (http://www.php.net/docs.php). They're both good reads -- have fun.
