Ajax (updateMyCart.php) :

    session_start();
    if(!empty($_SESSION["shopping_cart"])){  
        include "inc/config.php";
        $sl = 1;
        $totalPrice=0;  
        foreach($_SESSION["shopping_cart"] as $keys => $values){ 
            $query=mysqli_query($me, "SELECT * FROM `pro_item` WHERE `id`='".$values['item_id']."'");
            $proDetails=mysqli_fetch_assoc($query);
            $totalPrice=$totalPrice+($proDetails['price']*$values['item_quantity']);
        }

        $shippingCharge=0;
        if ($totalPrice>299) {
            $shippingCharge=0;
        }else{
            $shippingCharge=50;
        }
        $discount=0;

        $grandTotal=0;
        $grandTotal=$totalPrice+$shippingCharge-$discount;
        if ($shippingCharge=='0') {
            $shippingCharge='Free Shipping';
        }else{
            $shippingCharge="₹".$shippingCharge;
        }
echo    '   <tbody>
                <tr>
                    <th>Sub Total : </th>
                    <td><span class="price">₹'.$totalPrice.'</span></td>
                </tr>
                <tr>
                    <th> Shipping Charge:</th>
                    <td><span class="price">'.$shippingCharge.'</span></td>
                </tr>
                <!--tr>
                    <th> Discount:</th>
                    <td><span class="price">-₹'.$discount.'</span></td>
                </tr-->
                <tr>
                    <th class="cart_btn_cntnt"> Grand Total :</th>
                    <td><span class="cart_btn_cntnt_clr">₹'.$grandTotal.'</span> </td>
                </tr>
            </tbody>';

        }else{
            echo "Empty Cart";
        }
?>

Script (jQuery) :

function updateParoCart(){
    $('#myParoCart').load('updateMyCart.php',function () {
         //$(this).unwrap();
    });
}
updateParoCart(); // This will run on page load
setInterval(function(){
    updateParoCart() // this will run after every 5 seconds
}, 100);

When i had run this code at my localhost (XAMPP) there are i’m not facing any error but after uploading it to my server i’m getting error that is i’m getting empty $_SESSION['shopping_cart'] WHERE i had used $_SESSION['shopping_cart'] on my HTML file and that working fine at both place (Live & Local).

I had Search on Internet also here and i had found some solution like settings for php.ini files but can’t understand how to apply that.
