PHP Product Catalog Script

PHP Product Catalog Script for my computer shop to display the products in my website.
I am looking for a PHP / MySQL script (not ecommerce script as Magento or Prestashop) to build a website similar to these :

http://www.drezzy.it/uomo/calzature

Where products list are shown on rows and there is a sidebar to select different categories without price, brand, gender, ...

Should be more like a product comparison website than an ecommerce script with shopping cart. Actually shopping cart is not required

Try VamShop 2 - https://www.codester.com/items/14237/vamshop-2-ecommerce-cms

You can disable buy buttons and shopping cart box.

All other features available alreay: product filters, brand etc...
