PHP命名规范

使用PHP写的框架必然有其自身的一定规范,在ThinkPHP中亦然。下面是使用 ThinkPHP 应该尽量遵循的命名规范:

? 类文件都是以.class.php 为后缀(这里是指的 ThinkPHP 内部使用的类库文件,不代表外部加载的类库文件),使用驼峰法命名,并且首字母大写,例如DbMysql.class.php

? 函数、配置文件等其他类库文件之外的一般是以.php为后缀(第三方引入的不做要求)。

? 确保文件的命名和调用大小写一致,是由于在类Unix系统上面,对大小写是敏感的(而ThinkPHP在调试模式下面,即使在 Windows 平台也会严格检查大小写)。

? 类名和文件名一致(包括上面说的大小写一致),例如UserAction类的文件命名是 UserAction.class.php InfoModel类的文件名是 InfoModel.class.php

? 函数的命名使用小写字母和下划线的方式,例如get_client_ip

? Action控制器类以 Action为后缀,例如 UserAction InfoAction

? 模型类以Model 为后缀,例如UserModel InfoModel

? 方法的命名使用驼峰法,并且首字母小写,例如getUserName

? 属性的命名使用驼峰法,并且首字母小写,例如tableName

? 以双下划线“__ ”打头的函数或方法作为魔法方法,例如__call__autoload

? 常量以大写字母和下划线命名,例如HAS_ONEMANY_TO_MANY

? 配置参数以大写字母和下划线命名,例如HTML_CACHE_ON

? 语言变量以大写字母和下划线命名,例如MY_LANG,以下划线打头的语言变量通常用于系统语言变量,例如_CLASS_NOT_EXIST_

? 数据表和字段采用小写加下划线方式命名,例如think_useruser_name

特例:

ThinkPHP里面,有一个函数命名的特例,就是单字母大写函数,这类函数通常是某些操作的快捷定义,或者有特殊的作用。例如,ADSL 方法等等,他们有着特殊的含义,后面会有所了解。

另外一点,ThinkPHP默认使用 UTF-8编码,所以请确保你的程序文件采用 UTF-8 编码格式保存,并且去掉 BOM 信息头(去掉 BOM 头信息有很多方式,不同的编辑器都有设置方法,也可以用工具进行统一检测和处理)。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
