Well that's fairly easy, as - if you done it correctly - every checkbox has a name, and if this checkbox has been ticked, the POST or GET variable will hold a value named "on", after submitting the form. A standard code to check wether it has been submitted and checked can be something like:
if(isset($_POST['checkbox1']) && !empty($_POST['checkbox1'])){
do something here...
}
that's it.
