The PHP scripting language is predominantly used to add executable content to Web pages. This course will teach you the fundamentals of programming in PHP, as well as Web-related issues such as linking a series of forms together into a session, maintaining state if multiple users are on your site at the same time, cookies, security and other matters. The course also also covers PHP's interfacing to relational databases in some depth, with a particular study of MySQL.
