PHPDocumentor 注释规范整理

 你会写注释么？从我写代码开始，这个问题就一直困扰着我，相信也同样困扰着其他同学。以前的写注释总是没有一套行之有效的标准，给维护和协同开发带了许多麻烦，直到最近读到了phpdocumentor的注释标准。

下面对phpdocumentor的注释标准进行总结：

Type（数据类型）:

1. string 字符串类型
2. integer or int 整型
3. boolean or bool 布尔类型 true or false
4. float or double 浮点类型
5. object 对象
6. mixed 混合类型 没有指定类型或不确定类型时使用
7. array 数组
8. resource 资源类型 （如数据库查询返回）
9. void 空值（控制器返回值经常使用）
10. null null类型
11. callable 回调函数
12. false or true 只返回true or fasle 时使用
13. self 自身
