PHP session variable within other variable

Question

I have a page (cart page in ecommerce) with some data id like to access via PHP so I can mail it.

When I print all session variables using print_r( $_SESSION ); I get the following code.

I want to echo the value of "total".

I am using $_SESSION['cart']['total']; but it doesn't work.

All other outputs like "currency" and "language" are displayed as they should be.

What am I doing wrong here?

['cart']->total, since cart is an object?

Looks like cart is an object.

So, you should be able to access it via:

$_SESSION['cart']->total;

$_SESSION['cart'] is an object, then total is it's property: $total = $_SESSION['cart']->total;

cart is an object so it should be something like

 $_SESSION['cart']->total;

or if total is private or the corresponding class doesn't have a magic getter __get(); that could do it (or check the Class API for the public method name that returns $this->total;):

 $_SESSION['cart']->getTotal();

@user1721135 I believe my answer is the most generic as sometimes the variable of an object could be private and no __get() is defined in the class. If you agree please accept it as answer :) thanks!

From your output,

["cart"]=>
  &object(shoppingCart)#1 (5) {
    ...
    }
    ["total"]=>    float(115.9)

The value $_SESSION['cart'] is a PHP Object. You should access the total using:

$_SESSION['cart']->total;
