How to set up grouping in ThinkPHP

ThinkPHP is a very popular PHP development framework. It provides rich functions and easy-to-use interfaces, allowing us to develop Web applications more efficiently. In the process of using ThinkPHP, we sometimes need to group our applications to facilitate our project management and better collaborative development. In this article, we will introduce how to set up grouping in ThinkPHP.

1. What is grouping?

In ThinkPHP, grouping is to divide the controller, model, view and other files in the application according to business logic, thereby placing different functions in different locations. Grouping can help us better organize and manage code, and can also improve the readability and maintainability of code.

2. How to set up groups?

In ThinkPHP, we can set the grouping through the configuration file. First, find the config folder in the root directory of the application, which contains a series of configuration files. We need to find the app.php file. After opening it, you can see the following content:

return [
    // 默认应用
    'default_app' => 'index',
    // 应用映射（自动多应用模式有效）
    'app_map' => [],
    // 域名绑定（自动多应用模式有效）
    'domain_bind' => [
        // 'admin.domain.com' => 'admin',
    ],

    // 其他更多的配置项
    // ...
];

In this file, we can see a lot of configuration items, among which default_app is the default application name . If we want to set up groups, we need to change default_app to our own application name. For example, we now have a background application named admin, then we can modify default_app in the app.php file as follows:

return [
    // 默认应用
    'default_app' => 'admin',
    // 应用映射（自动多应用模式有效）
    'app_map' => [],
    // 域名绑定（自动多应用模式有效）
    'domain_bind' => [
        // 'admin.domain.com' => 'admin',
    ],

    // 其他更多的配置项
    // ...
];

This way you can change the default application to admin.

But if we have multiple groups, how to set them up? At this time we need to use the automatic multi-application mode provided by ThinkPHP. The specific method is as follows:

return [
    // 默认应用
    'default_app' => 'index',
    // 应用映射（自动多应用模式有效）
    'app_map' => [
        'admin' => 'admin',
        'home' => 'index',
    ],
    // 域名绑定（自动多应用模式有效）
    'domain_bind' => [
         'home.tp.cn'     => 'home',
         'www.tpadmin.cn' => 'admin',
    ],

    // 其他更多的配置项
    // ...
];

In this configuration file, we can see the settings of the app_map parameter. Here we can set the parameters for each Set an application name for each group, such as admin and home. At this time, we need to create two folders admin and in the application root directory. home stores the code of background and foreground applications respectively. At the same time, domain_bind is also used to bind domain names and applications.

In multi-app mode we need to put the main code into the index app as this is the default app.

3. Summary

When using ThinkPHP for web application development, we will definitely need to group it. Through group settings, we can divide different functions and files in the application according to business logic, which facilitates code organization and management, and also improves the readability and maintainability of the code. In ThinkPHP development, we can perform group settings by modifying the configuration file. The specific method is as described above.
