    require_once (DIR_WS_MODEL . "/ProductsMaster.php");

    /*Shopping Cart Loop  */
    $static_basket_array=array('basket_id'=>'user_basket.basket_id','user_basket.date'=>'date AS created_date','cart_detail'=>'user_basket.cart_detail AS products');

                   $datad = $objProductsMaster->getProductsDesc();
                   $products= array('product_id'=>$data['product_id'],'product_title'=>$datad[0]['products_title']);
                }
                $cart_details_value=array();
                $cart_details_value= $products;

            }

            $output[$field_key]= $cart_details_value;
            $all['shopping_cart']=$output;
        }
        echo "<pre>";print_r($output1);echo "</pre>";exit;
        $output1[]= $all;
    } 

    /*End OF Shopping Cart  */

     if(empty($output1))
        $output=array('Message'=>NO_RECORD_FOUND);

        return $output1;


}

}

Here in $output1 i always get the latest data, but i want all the data . The data is been over written in $output1 .

So how can i add $customer_details_value as well as $cart_details_value both in $output1.

Here after adding $cart_details_value in $output it over rides value of $customer_details_value in $output1

Answer

You need to define your $output1 before the loops:

$output1 = [];

And better start using informative variable names, to easy read the code and find the errors.
