to the next level.
- You have experience with other programming languages and want to develop
Web applications with PHP.

PHP for the World Wide Web - Visual QuickStart Guide - Larry Ullman - 2001.

    While there are several professional-level books available on PHP, there are few guides to this open-source scripting language for students who may be familiar with HTML but are not studying to be professional programmers. PHP for the World Wide Web: Visual QuickStart Guide is a task-based, visual reference guide that features step-by-step instructions and plenty of screen shots-the ideal way for students to learn the basics of PHP, starting with basic syntax, testing scripts, working with variables, creating Web applications, and more.
