add to variable on radio button click php

i've got the following radio buttons in a form

<input type="radio" name="shipping" value="Shipping($30)">Express Shipping($30)
<input type="radio" name="shipping" value="Shipping($15)">Regular Shipping($15)
<input type="radio" name="shipping" value="Shipping(Free)">Free Shipping

and the variables

$totalNoShip;
$totalWithShip;

The totalNoShip variable holds the total before shipping. I want the variable totalWithShip to be updated when one of the radio buttons is clicked. once this is done I want to print the variable in a span <span class="finalPrice"> final value here </span> how do i go about doing this?

Change your HTML to

<input type="radio" name="shipping" value="30">Express Shipping($30)
<input type="radio" name="shipping" value="15">Regular Shipping($15)
<input type="radio" name="shipping" value="0">Free Shipping

<input type="hidden" name="total" value="0">
<span class="finalPrice"></span>

Then do something with JS like:

$(document).ready(function(){

    $('input[name="shipping"]').click(function(){

        var $mValue = $(this).val();
        $('.finalPrice').text($mValue);
        $('input[name="total"]').val($mValue);

    });
});

Then after you POST, Validate your total to see if it is related to the selected Shipping type
