PHP Session Array not working when adding more than 2 items

Question

I want to add products to my array, but every time I add a product, it replaces the old one in the array.

When I add 2 things, it works fine:

Array ( [0] => 2 [1] => 8 )

But when I try to add a third item or more, it replaces the second item in the array:

Array ( [0] => 2 [1] => 10 )

Here is my code:

  session_start();

  if(isset($_POST['inCart']))
  {
       $id = $_POST['id'];

       if(!empty($_SESSION['cart']))
       {     
          $session = $_SESSION['cart'];
          $session[] = $id;

          print_r($session);
       }

       else
       {
          $_SESSION['cart'] = array($id); 
       }
  }

As i see you forgot set SESSION with new data

if(!empty($_SESSION['cart']))
       {     
          $session = $_SESSION['cart'];
          $session[] = $id;

          $_SESSION['cart'] = $session;

          print_r($session);
       }

Thank you very much, was a stupid mistake of me. I also shortened my code now I know my mistake session_start(); if(isset($_POST['inWagen'])) { $id = $_POST['id']; if(isset($_SESSION['winkelwagen'])) { $_SESSION['winkelwagen'][] = $id; } else { $_SESSION['winkelwagen'] = array($id); } }
