Need PHP function and cal

I need a PHP function and calculation for the following-

web hosting:
$3, $6 or $12 monthly

plus $5 each month for each extra ordered (e.g. more space, bandwidth, etc... all the extras are charged at a flat $5 each per month).

The customer selects either the 3, 6 or 12 dollar plan and also selects the extras that they want.

The code needs to calculate their monthly charge, plus add $5 for each extra that they chose based on their plan.

What would be the best way to code this?

Thanks

there are two options

Either you can use javascript or PHP

javascript is not good as all code is visible to client

so better use php

the best way to code this is AJAX / PHP

 

Yes it needs to be in PHP.

So far I have this but need to define the arrays somehow so the $5 for each extra is added properly, plus the plan cost.


// Calculate extras
if (array_key_exists('extras', $_POST)) {
$extras_array = $_POST['extras'];
foreach ($extras_array as $extras)
$total_extras = $extras += 5;
}
// Calculate fee
if (array_key_exists('plan', $_POST)) {
$plan['0'] = '3';
$plan['1'] = '6';
$plan['2'] = '12';
foreach ($plan_array as $plan)
$fee = $total_extras + $plan;
echo "<p>Monthly subscription fee: $$fee</p>";
}

Am still learning so have probably got things mixed up.

I have a done a script that shows how it works with AJAX/PHP. PM me if you want to see because i don't have permission to submit links.

 

Any help with this PHP coding would be much appreciated. I need to somehow add the price for each 'extra' that is selected and add it to the cost of the monthly plan.
