Detailed thinkPHP5.0 framework module design

This article mainly introduces the thinkPHP5.0 frameworkmodule design, and briefly describes the thinkPHP5.0directory structure, naming standards and analysis in the form of examples The principles and access methods of the module Class Library are explained. Friends in need can refer to

. This article describes the thinkPHP5.0 framework module design with examples. Share it with everyone for your reference, the details are as follows:

The 5.0 version has a flexible design for the function of the module. It adopts a multi-module architecture by default and supports a single module design. The namespace## of all modules is #Both use app as the root namespace (can be configured to change).

Directory structure

The standard application and module directory structure is as follows:

├─application           应用目录（可设置）
│  ├─common             公共模块目录（可选）
│  ├─common.php         公共函数文件
│  ├─route.php          路由配置文件
│  ├─database.php       数据库配置文件
│  ├─config.php         应用配置文件
│  ├─module1            模块1目录
│  │  ├─config.php      模块配置文件
│  │  ├─common.php      模块函数文件
│  │  ├─controller      控制器目录
│  │  ├─model           模型目录
│  │  ├─view            视图目录
│  │  └─ ...            更多类库目录
│  │
│  ├─module2            模块2目录
│  │  ├─config.php      模块配置文件
│  │  ├─common.php      模块函数文件
│  │  ├─controller      控制器目录
│  │  ├─model           模型目录
│  │  ├─view            视图目录
│  │  └─ ...            更多类库目录

Follow the naming convention of ThinkPHP5.0, and the module directories all use lowercase and Underline naming.

Please avoid using PHP reserved keywords in the module name (see http://php.net/manual/zh/reserved.keywords.php for the list of reserved words), otherwise it will cause system errors. .

The common module is a special module that prohibits direct access by default. It is generally used to place some public class libraries for

inheritance of other modules.

Module Class Library

The namespace of the class library file under a module uniformly starts with app\module name, for example:

// index模块的Index控制器类
app\index\controller\Index
// index模块的User模型类
app\index\model\User

where app It can be changed by definition. For example, we modify it in the application configuration file:

'app_namespace' => 'application',

Then, the class library namespace of the index module becomes:

// index模块的Index控制器类
application\index\controller\Index
// index模块的User模型类
application\index\model\User

More about class libraries and For the relationship between namespaces, please refer to the next previous article "Detailed Explanation of ThinkPHP5.0 Framework Namespaces".

Module and controller hiding

Since the default is to use multi-module support, the current module must be identified in the URL address in the case of multiple modules. If there are only For a module, you can bind the module by adding the following code to the public file of the application:

// 绑定当前访问到index模块
\think\Route::bind('index');

After binding, our URL access address becomes:

http://serverName/index.php/控制器/操作/[参数名/参数值...]

The module is the index module.

If your application is relatively simple and has only one module and controller, you can bind the module and controller in the application public file, as follows:

// 绑定当前访问到index模块的index控制器
\think\Route::bind('index/index');

After setting, Our URL access address becomes:

http://serverName/应用入口/操作/[参数名/参数值...]

The module accessed is the index module, and the controller is the Index controller.

Single module

If your application is relatively simple and has only one module, it can be further simplified to use a single module structure as follows:

First define it in the application configuration file:

// 关闭多模块设计
'app_multi_module' => false,

Then, adjust the structure of the application directory as follows:

├─application        应用目录（可设置）
│  ├─controller      控制器目录
│  ├─model           模型目录
│  ├─view            视图目录
│  ├─ ...            更多类库目录
│  ├─common.php      函数文件
│  ├─route.php       路由配置文件
│  ├─database.php    数据库配置文件
│  └─config.php      配置文件

URL access address becomes

http://serverName/index.php（或者其它应用入口）/控制器/操作/[参数名/参数值...]

At the same time, The namespace of the application class library under the single module design has also been adjusted, for example:

The original

app\index\controller\Index
app\index\model\User

becomes

app\controller\Index
app\model\User

More URL simplification and Customization is also possible through the URL routing feature.
