convert array to json from SESSION variable

Question

I am trying to convert an array where I store some 'products' ($_SESSION['cart']) into a JSON format, but it has been impossible for me

The structure of the $_SESSION['cart'] variable is

$_SESSION['cart']['id_product']['quantity']

I'm using this code to obtain each product, I think i can obtain an array from here

foreach($_SESSION['cart'] as $id_product => $quantity) { 
code
}

Thanks

Just use the built-in function json_encode:

$myjson = json_encode($_SESSION['cart']);

Substitute whatever variable you want, e.g., $_SESSION['cart']['id_product']['quantity'].

   <?php
      session_start();
      $_SESSION['cart'] = array('test' => 'stuff');
      echo json_encode($_SESSION); //Prints {"cart":{"test":"stuff"}}
   ?>
