[SOLVED] PHP SESSION HELP

[Morty222]

I have this is the session:

 

foreach ($_SESSION['cart'] as $key=>$c){

                                       

$total = $_SESSION['cart'][$key]['cost'];

                                       

}

 

This gives me a total for each product, works fine.

 

How can I add the totals together to get a grand total?

 

Thanks in advance !!!!

$total += $_SESSION['cart'][$key]['cost'];
