Beginning PHP and PostgreSQL E-Commerce: From Novice to Professional (Beginning, from Novice to Professional)

The book promotes good programming practices, including the separation of presentation code, business code, and data access code using a 3-tier architecture. PDO (PHP Data Objects) is used to connect to the database, and PostgreSQL functions are used to store the data logic. The Smarty templating engine is used to create the presentation layer. For a preview of what this book will teach you, take a look at the HatShop shopping cart demo.
