Dynamically call function corresponding to html checkboxes

In my code I created chef class which can have three function I have another ItalianChef which inherits chef class and additionally have two function. What I want to do is in a user form user will first choose a chef and choose dish after that I will show which image of the dish user have choosen. If selected chef doesn't have any dish he can cook I will show cannot cook. The problem is how can I call the function in 'chef' and 'ItalianChef' class according to the checkbox choosen from user. here is the code

        <?php 
        class chef{
            function makeFrenchFry()
            {
                echo "made french fry <br>";
                ?>
                <img src="media/frenchfry.gif" alt="">
                <?php
            }
            function makeCrabFry()
            {
                echo "made crab  fry <br>";
                ?>
                <img src="media/crabfry.gif" alt="">
