3.2 引入语句

引入语句应该位于文件的头部,并在引入时说明引入文件的作用。例如:

//数据库操作类
require( “db.php” );
3.3 类的声明

1 类文档注释(/**……*/) 该注释中所需包含的信息,参见"文档注释"
2 类的声明
3 类实现的注释(/*……*/)如果有必要的话 该注释应包含任何有关整个类的信息,而这些信息又不适合作为类文档注释。
4 类的(静态)变量 首先是类的公共变量,随后是保护变量,再后是包一级别的变量(没有访问修饰符,access modifier),最后是私有变量。
5 实例变量 首先是公共级别的,随后是保护级别的,再后是包一级别的(没有访问修饰符),最后是私有级别的。
6 构造器
7 方法 这些方法应该按功能,而非作用域或访问权限,分组。例如,一个私有的类方法可以置于两个公有的实例方法之间。其目的是为了更便于阅读和理解代码
