What are the common Kohana framework operations in PHP programming?

Kohana framework is a lightweight PHP framework that follows the MVC pattern and can help developers quickly develop web-based applications. When using the Kohana framework, there are some common operations that must be mastered. This article will introduce some common operations in the Kohana framework for reference by PHP programmers.

1. Route

Routing is a very important Kohana framework operation. Routing defines the mapping relationship between URL addresses and controllers/operation methods. Developers can manage and process URL address requests through routing. In the Kohana framework, routing rules are usually defined in the app/bootstrap.php file.

Specific routing rules can use regular expressions to match variable values in URL addresses. Developers can customize routing rules according to actual needs to achieve more flexible URL address management.

2. Controller(Controller)

In the Kohana framework, the controller is one of the cores of the MVC pattern. The controller is responsible for responding to requests from URL addresses and processing corresponding business logic. Developers can operate models and views through controllers to complete operations such as adding, deleting, modifying, and querying data.

In the Kohana framework, controllers are usually named in a naming method similar to "Controller_XXX", where "XXX" is the name of the controller. Each controller needs to contain at least one action method to respond to requests from the URL address.

3. Model

In the Kohana framework, models are mainly used to operate data in the database. Through the ORM (Object Relational Mapping) function provided by the Kohana framework, developers can operate the database very conveniently.

In the Kohana framework, each model needs to inherit the Kohana_Model class and define the corresponding fields and relationships. In addition, developers can also implement CRUD (add, delete, modify, query) operations on data by defining model methods.

4. View(View)

The view is part of the user interface. It is responsible for presenting the data in the model and interacting with the user. Views in the Kohana framework are usually defined and implemented using PHP files.

In the Kohana framework, the view completes the rendering of the page by calling the data returned in the controller operation method. Views in the Kohana framework support template engines. Developers can use commonly used template engines, such as Smarty, to render views.

5. Request

In the Kohana framework, request is used to represent an HTTP request from the client (browser). Through the request object, developers can obtain information related to HTTP requests, such as request method, request path, request parameters, etc.

The request object in the Kohana framework is usually implemented using the Kohana_Request class. This class provides many built-in methods for conveniently obtaining HTTP request-related content.

Summary:

The Kohana framework is a very practical and fully functional PHP framework. When using the Kohana framework, developers need to master some basic operations, such as routing, controllers, models, views, and requests. Only by firmly mastering these basic operations can you develop quickly in the Kohana framework.
