2、如果你在多个文件中调用了一个数据库连接，创建一个connection.php文件保存你的连接变量，在需要的地方将这个文件包括进来。
3、对于小型项目，将你所有的函数写在一个文件中，如果是大型项目就写在对象中，然后在需要的地方包括这个文件。
4、如果你的包括文件失控，可以创建一个include文件包含所有的.inc文件，然后在你需要的地方包括这一个include文件就可以了。
5、为你的代码编写文档，当你3个月后看这些代码时，你会用得着。
6、代码排版，没有什么比可读性更重要了。
7、将逻辑和表现层分开。
8、写类时，确保你知道何时是耦合的最佳时机，何时是扩展的最佳时机。
9、接口是你的朋友。
10、当项目变得越来越大时，将你的代码分解成模型、视图和控制器是超级骗子。
11、在没有剥掉HTML标记前永远不要输出POST和GET数据，
12、永远不要相信来自用户的输入，即使她是你妈妈。
13、永远不要把类名搞重复了，记住，是永远! (fblww-0117)
