How do i get total quantity from this code

[wixil]

<?php
session_start();

ini_set('display_errors', 1);
error_reporting(E_ALL);

define("PRODUCTIMAGE",0);
define("PRODUCTCODE", 1);
define("PRODUCTNAME", 2);
define("QUANTITY", 3);
define("PRICE", 4);

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
   if (isset($_POST['productcode']))
   {
      AddToCart();
   }
   else
   {
      $action = isset($_POST['action']) ? $_POST['action'] : '';
      $value = strtoupper(substr($action, 0, 5));
      switch ($value)
      {
      // continue shopping
      case "CONTI":
         header("Location: "."products.html");
         break;

      // recalculate
      case "RECAL":
         RecalculateCart();
         break;

      // proceed to checkout
      case "CHECK":
         header("Location: "."customer.php");
         break;
      }
   }
}


function AddToCart()
{
   $cart = isset($_SESSION['cart']) ? $_SESSION['cart'] : '';
   $itemcount = isset($_SESSION['itemcount']) ? $_SESSION['itemcount'] : 0;

$productname = $_POST['productname'];
$extra_price = 0;
$productname = stripslashes($productname);

// Let's see if this product already exists
   for ($i=0; $i < $itemcount; $i++)
   {
     if ($cart[PRODUCTNAME][$i] == $productname) {
         $cart[QUANTITY][$i] = $cart[QUANTITY][$i] + intval($_POST['quantity']);
         $_SESSION['cart'] = $cart;
         $_SESSION['itemcount'] = $itemcount;
         header("Location: "."cart.php");
         exit;
   }
   }

   $cart[PRODUCTIMAGE][$itemcount] = $_POST['productimage'];
   $cart[PRODUCTCODE][$itemcount] = $_POST['productcode'];
   $cart[PRODUCTNAME][$itemcount] = $_POST['productname'];
   $cart[QUANTITY][$itemcount] = intval($_POST['quantity']);
   $cart[PRICE][$itemcount] = $_POST['price'];
   $itemcount = $itemcount + 1;

   $_SESSION['cart'] = $cart;
   $_SESSION['itemcount'] = $itemcount;
}


function RecalculateCart()
{
   $cart = isset($_SESSION['cart']) ? $_SESSION['cart'] : '';
   $itemcount = isset($_SESSION['itemcount']) ? $_SESSION['itemcount'] : 0;

   for ($i=0; $i<$itemcount; $i++)
   {
      $quantity = $_POST['quantity'.($i)];
      if (empty($quantity))
      {
         $quantity = 0;
      }
      else
      if (($quantity < 0) || (!is_numeric($quantity)))
      {
         $quantity = 0;
      }
      $cart[QUANTITY][$i] = intval($quantity);
   }

   for ($j=0; $j<$itemcount; $j++)
   {
      $quantity = $cart[QUANTITY][$j];

      // remove item from the cart
      if ($quantity == 0)
      {
         $itemcount--;
        
         $curitem = $j;

         while(($curitem+1) < count($cart[0]))         
         {
            for ($k=0; $k<4; $k++)
            {
               $cart[$k][$curitem] = $cart[$k][$curitem+1];
               $cart[$k][$curitem+1] = '';
            }
            $curitem++;
         }
      }
   }
   $_SESSION['itemcount'] = $itemcount;
   $_SESSION['cart'] = $cart;
}

?>

And the cart display table code is

<?php

$cart = isset($_SESSION['cart']) ? $_SESSION['cart'] : '';
$itemcount = isset($_SESSION['itemcount']) ? $_SESSION['itemcount'] : 0;

$strHTML = "";

if ($itemcount == 0)
{
   $strHTML = "<h3>Your shopping cart is empty.</h3>";
}
else
{
   $strHTML = "<div style=\"overflow:auto; height=100%;\">"."\n";
   $strHTML .= "<table border=\"0\" cellpadding=\"9\" cellspacing=\"0\" width=\"100%\">"."\n";
   $strHTML .= "<tr>"."\n";
   $strHTML .= "<td style=padding-top:12px;padding-bottom:12px;background-color:#04AA6D;color:white;font-size:18px;font-family:TimeBurner;>Product</td>"."\n";
   $strHTML .= "<td style=padding-top:12px;padding-bottom:12px;background-color:#04AA6D;color:white;font-size:18px;font-family:TimeBurner;>Description</td>"."\n";
   $strHTML .= "<td style=padding-top:12px;padding-bottom:12px;background-color:#04AA6D;color:white;font-size:18px;font-family:TimeBurner;>Quantity</td>"."\n";
   $strHTML .= "<td style=padding-top:12px;padding-bottom:12px;background-color:#04AA6D;color:white;font-size:18px;font-family:TimeBurner;>Price</td>"."\n";
   $strHTML .= "<td style=padding-top:12px;padding-bottom:12px;background-color:#04AA6D;color:white;font-size:18px;font-family:TimeBurner;>Total</td></tr>"."\n";

   $total = 0;
   for ($i=0; $i<$itemcount; $i++)
   {
      $strHTML .= "<tr>"."\n";
      $strHTML .= "<td>".$cart[PRODUCTIMAGE][$i]."</td>"."\n";
      $strHTML .= "<td style=font-size:14px;font-family:TimeBurner;font-weight:bold;>".$cart[PRODUCTNAME][$i]."</td>"."\n";
      $strHTML .= "<td><input type=\"text\" name=\"quantity".($i)."\" value=\"".$cart[QUANTITY][$i]."\" size=\"1\" style=padding:5px;border-radius:2px;background:#ffffff;border-width:1px;border-style:solid;border-color:#ccc;></td>"."\n";
      $strHTML .= "<td style=font-size:14px;font-family:TimeBurner;font-weight:bold;>"."$".number_format($cart[PRICE][$i],2)."</td>"."\n";
      $strHTML .= "<td style=font-size:14px;font-family:TimeBurner;font-weight:bold;>"."$".number_format($cart[PRICE][$i]*$cart[QUANTITY][$i],2)."</td>"."\n";
      $strHTML .= "</tr>"."\n";
      $total = $total + ($cart[PRICE][$i]*$cart[QUANTITY][$i]);
   }

   $strHTML .= "<tr>"."\n";
   $strHTML .= "<td></td><td></td><td></td>"."\n";
   $strHTML .= "<td style=font-size:20px;font-family:TimeBurner;font-weight:bold;>TOTAL</td>"."\n";
   $strHTML .= "<td style=font-size:20px;font-family:TimeBurner;font-weight:bold;>"."$".number_format($total, 2)."</td>"."\n";
   $strHTML .= "</tr>"."\n";
   $strHTML .= "</table>"."\n";
   $strHTML .= "</div>"."\n";
}
echo $strHTML;

Use the <> button in the toolbar when posting code. I have done it for you - this time.

[Barand]

Does this do it?

Total_qty = array_sum($cart['QUANTITY']);

Thanks @ Barand

I am a somewhat php and js beginner. i needed to implement something like the attached png file probably by echo.

[Barand]

As you show a currency symbol, are you sure you don't want the total price?

[Barand]

$total_price = array_sum($cart['PRICE']);

echo "₦  $total_price";

Gives something like

Use FontAwesome or similar for the cart icon.
