php - Laravel Store Array in Session

Question

I have been having trouble storing an array in session. I am making a shopping cart and it doesn't seem to work.

public function __construct(){

  $product = array(1,2,3,4);
  Session::push('cart', $product);

}

and then retrieve it in the view like this.

{{Session::get('cart')}}

However I keep getting an error like this.

htmlentities() expects parameter 1 to be string, array given

Any clues and advice on how to create a shopping cart that stores an array of items.

If you need to use the array from session as a string, you need to use Collection like this:

$product = collect([1,2,3,4]);
Session::push('cart', $product);

This will make it work when you will be using {{Session::get('cart');}} in your htmls. Be aware of Session::push because it will append always the new products in sessions. You should be using Session::put to be sure the products will be always updating.
