PHP is a server-side scripting language that is easy to learn and use. With little programming knowledge, you can use PHP to build a truly interactive WEB site. This tutorial does not want you to fully understand this language, but allows you to join the development of dynamic web sites as soon as possible. I suppose you have some basic HTML (or HTML editor) knowledge and some programming ideas.
1. Introduction
PHP is one of the tools that allow you to generate dynamic web pages. PHP webpage files are processed as common HTML webpage files. During editing, you can use the conventional HTML editing method to compile PHP.
PHP stands for Hypertext Preprocessor (PHP: Hypertext Preprocessor ). PHP is completely free and free to spend, you can download from PHP official site (http://www.php.net) freely. PHP complies with the GNU Public License (GPL), under which many popular software such as Linux and Emacs are born.

Information on how to install PHP on a Windows PC or Unix server can be found on the official site of PHP. The installation process is simple.

Now we have a new Zend engine that can rival the speed of mod_perl, and PHP4 can make full use of it. PHP4 is still in BETA testing. Andy Gutmans and Zeev Suraki are the main authors of Zend. You can go to the Zend site (http://www.zend.com) to learn more.
