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