说明：  PHP是一种易于学习和使用的服务器端脚本语言。只需要很少的编程知识你就能使用PHP建立一个真正交互的WEB站点。本教程并不想让你完全了解这种语言，只是能使你尽快加入开发动态web站点的行列。我假定你有一些HTML（或者HTML编辑器）的基本知识和一些编程思想。
(PHP is an easy to learn and use server-side scripting language. Requires very little programming knowledge you can use PHP to build a truly interactive WEB site. This tutorial does not want you to fully understand the language, but enable you to develop dynamic web sites as soon as possible to join the ranks. I assume you have some HTML (or HTML editor) and some basic knowledge of programming ideas.)
