Implement custom routing rules in Think PHP

《Implementing custom routing rules in Think PHP requires specific code examples》

When developing using the Think PHP framework, we often encounter the need for custom routing Rules situation. By default, Think PHP will locate the corresponding controller and method based on the controller name and method name in the URL. But sometimes we need to define routing rules more flexibly to better meet project needs.

It is very simple to implement custom routing rules in Think PHP. You only need to make the corresponding settings in the routing configuration file of the project. Below we will use a specific example to show how to implement custom routing rules in Think PHP.

Suppose we have a project that needs to implement a controller named "article", which contains the function of displaying the article list and article details. We hope that users can access the article list and article details through the following URL:

• Article list:/article/list
• Article details:/article/detail/id

First, we need to add the corresponding routing rules in the project's routing configuration file (generally route.php):

return [
    // 默认路由规则
    '__pattern__' => [
        'id' => 'd+',
    ],

    // 自定义路由规则
    'article/list' => 'article/index',
    'article/detail/:id' => 'article/detail',
];

In the above configuration file, we defined Two custom routing rules. The first rule ' article/list' => 'article/index', means mapping the /article/list path to the index method of the article controller to display articles list. The second rule 'article/detail/:id' => 'article/detail', means mapping the path /article/detail/id with parameters to the article control The detail method of the handler is used to display the article details of the specified ID.

Next, we need to write corresponding methods in the controller to handle these two routes:

namespace appcontroller;

use thinkController;

class Article extends Controller
{
    public function index()
    {
        // 显示文章列表的业务逻辑
        return "显示文章列表";
    }

    public function detail($id)
    {
        // 根据$id显示对应文章详情的业务逻辑
        return "显示文章详情，ID为：" . $id;
    }
}

In the above controller code, we define an Article controller, Contains two methods, index and detail, which are used to process the business logic of article lists and article details respectively. The index method is used to display the article list, while the detail method displays the details of the corresponding article based on the passed $id parameter.

Finally, when the user accesses /article/list, the index method of the Article controller will be triggered to display the article list; while accessing /article/detail/1, the detail method of the Article controller will be triggered, and 1 will be passed in as $id to display the details of the article with ID 1.

Through the above examples, we can see that it is very simple to implement custom routing rules in Think PHP. You only need to define the corresponding rules in the routing configuration file and write the corresponding methods in the controller. Routing customization. This flexible routing mechanism helps us better organize and manage project routing rules, improve development efficiency, and meet specific needs.
