Looping Thru Multidimensional Array

PHP
1

Can anyone point out why this is not incrementing items already in the cart? It simply adds new rows to the cart.


session_start();

if(isset($_SESSION['CART']) == false || isset($_SESSION['CART']['ITEMS']) == false) {
       $_SESSION['CART']['ITEMS'] = array();
}


foreach($_POST AS $sku => $qty) {
		
        if (!empty($qty)) {
			
	// if the product sku is already in the cart, do this //
			
	foreach ($_SESSION['CART']['ITEMS'] as $cart_item_sku => $item) {
				
		if (($item['item_sku'] == $sku) && ($qty == '1')) {
					
                        $_SESSION['CART']['ITEMS'][$cart_item_sku]['item_qty']++;
			$found = true;
			break;
		}

		elseif (($item['item_sku'] == $sku) && ($qty > '1')) {
			$_SESSION['CART']['ITEMS'][$cart_item_sku]['item_qty'] = $_SESSION['CART']['ITEMS'][$cart_item_sku]['item_qty'] + $qty;
			$found = true;
			break;
		}

	}
			
	// if the product sku is not already in the cart, do this //
			
	if (!$found) {
                $_SESSION['CART']['ITEMS'][] = array('item_sku' => $sku, 'item_qty' => $qty);
        } 
}

$_SESSION[‘CART’][‘ITEMS’] = array(‘item_sku’ => $sku, ‘item_qty’ => $qty);

Should be

$_SESSION[‘CART’][‘ITEMS’][$cart_item_sku] = array(‘item_sku’ => $sku, ‘item_qty’ => $qty);
