How would i figure out the price difference efficiently with PHP?
<p>I have this <a href="http://posnation.com/shop_pos/step2/Bakery" rel="nofollow">page</a> and if you scroll to the second "Customize" in the middle of the page and you click you will see my print_r() for the products and the thing i am trying to do is figure out the difference in price between the selected and the other two products....all three products are in the array and if you look just below that you will see the radio buttons that i need....here is my php which looks awful...any suggestions  </p>

<pre><code>$current_price = $product[$selected_product]['product_price'];

$standard_price = $product["standard"]['product_price'] - $current_price;
$business_price = $product["business"]['product_price']  - $current_price;
$premium_price = $product["premium"]['product_price'] - $current_price;

if($standard_price == 0){
    $standard_price = "included";
}
if($standard_price &gt; 0){
    $standard_price = "subtract " . $standard_price;
}else{
    $standard_price = "add " . $standard_price;
}

if($business_price == 0){
    $business_price = "included";
}
if($business_price &gt; 0){
    $business_price = "subtract " . $business_price;
}else{
    $business_price = "add " . $business_price;
}

if($premium_price == 0){
    $premium_price = "included";
}
if($premium_price &gt; 0){
    $premium_price = "subtract " . $premium_price;
}else{
    $premium_price = "add " . $premium_price;
}
</code></pre>
