Changing dropdown list/check box options

Question

I have 4 drop-down lists / group of checkboxes in I need that after making a selection in any one list the options available in the other 3 lists change accordingly...either are not available for selection or are not present in the list itself.

I'm coding using PHP & MYSQL Could someone please help me with this. I'm new to PHP.

PHP is a server-sided programming language. *"After making a selection"* indicates that the drop-down list is already at the client-side. There is no way that PHP can make a change on the client-side, without help from a client-sided programming language such as javascript. — Sumurai8, Jul 14 '13 at 15:14

This can not be done with just PHP and MySQL. You need to use Javascript or jQuery. jQuery is the easiest to learn.

You can do it but very hard. You should use jQuery, it's easier than PHP.
