获取数组值[关闭]

After dumping session, I get below result. Can anybody please tell me how I can get the value "product_id" and "info" that are in array(2);

array(3) { 
    ["DYN_outskin"]=> string(3) "ten" 
    ["DYN_inskin"]=> string(3) "one" 
    ["cart"]=> array(1) { 
        ["2000_facebook"]=> array(2) { 
            ["product_id"]=> string(13) "2000_facebook" 
            ["info"]=> string(7) "nur1952"
        } 
    }
} 

Try like this:

$array['cart']['2000_facebook']['product_id'];
$array['cart']['2000_facebook']['info'];

$_SESSION["cart"]["2000_facebook"]["product_id"] ;

$_SESSION["cart"]["2000_facebook"]["info"] ;

iterate over cart:

foreach ($_SESSION["cart"] as $product){
  echo "Product info : {$product['info']} | Product ID : {$product['product_id']} <br/>" ;
}

It is always a good practice to display the array in a way that clearly displays the array structure, like so:

array(3) { 
  ["DYN_outskin"]=> string(3) "ten" 
  ["DYN_inskin"]=> string(3) "one" 
  ["cart"]=> array(1) { 
    ["2000_facebook"]=> array(2) { 
      ["product_id"]=> string(13) "2000_facebook" 
      ["info"]=> string(7) "nur1952" 
    } 
  } 
}

Now, its clear how you can access the needed elements:

$array["cart"]["2000_facebook"]["product_id"]
$array["cart"]["2000_facebook"]["info"]
