list items in cart code

 if(isset($_post["load_cart"]) && $_post["load_cart"]==1)     {          if(isset($_session["products"]) && count($_session["products"])>0){ //if have session variable             $cart_box = '<ul class="cart-products-loaded">';             $total = 0;             foreach($_session["products"] $product){ //loop though items , prepare html content                  //set variables use them in html content below                 $product_name = $product["product_name"];                  $product_price = $product["product_price"];                 $product_code = $product["product_code"];                 $product_qty = $product["product_qty"];                 $product_color = $product["product_color"];                 //$product_size = $product["product_size"];                  //$cart_box .=  "<li> $product_name (qty : $product_qty | $product_color  | $product_size ) &mdash; $currency ".sprintf("%01.2f", ($product_price * $product_qty)). " <a href=\"#\" class=\"remove-item\" data-code=\"$product_code\">&times;</a></li>";                  $cart_box .=  "<li> $product_name (qty : $product_qty | $product_color ) &mdash; $currency ".sprintf("%01.2f", ($product_price * $product_qty)). " <a href=\"#\" class=\"remove-item\" data-code=\"$product_code\">&times;</a></li>";                  $subtotal = ($product_price * $product_qty);                 $total = ($total + $subtotal);             }             $cart_box .= "</ul>";             $cart_box .= '<div class="cart-products-total">total : '.$currency.sprintf("%01.2f",$total).' <u><a href="view_cart.php" title="review cart , check-out">check-out</a></u></div>';             die($cart_box); //exit , output content         }else{             die("your cart empty"); //we have empty cart         }     }

remove item cart

if(isset($_get["remove_code"]) && isset($_session["products"])) {     $product_code   = filter_var($_get["remove_code"], filter_sanitize_string); //get product code remove      if(isset($_session["products"][$product_code]))     {         unset($_session["products"][$product_code]);     }      $total_items = count($_session["products"]);     die(json_encode(array('items'=>$total_items))); }

in above code how color of product should compared? e.g. cool t-shirt | blue , cool t-shirt | red , if cool t-shirt | red removed both should not removed.

can please me in this?
