How does php use the ThinkPHP7 framework?

With the development of Internet technology, PHP, as an important programming language, is widely used in website development. As an excellent PHP framework, the ThinkPHP framework has the advantages of high efficiency, scalability and easy maintenance. This article will introduce how to develop PHP through the ThinkPHP7 framework.

1. Framework construction

Before starting to use the ThinkPHP7 framework, you first need to install the PHP environment and Composer tool. Then enter the directory where the project is located on the command line and use the following command to create a new ThinkPHP7 project.

composer create-project topthink/think appname

Among them, appname represents your project name. At this time, Composer will automatically download the relevant framework code and dependent libraries, and create the basic file structure of the project.

2. Configuration files

In the ThinkPHP7 framework, all configuration information is stored in each configuration file in the config directory. By modifying these files, some configurations of the framework can be made.

Among them, common configuration files include:

1. app.php

This file contains the basic configuration information of the project, such as application name, default Time zone, log level, routing configuration, etc.

2. database.php

This file contains database connection information, such as database type, host, user name, password, and default database name.

3. cache.php

This file contains configuration information used in the cache component, such as cache type, server address, port, etc.

By modifying the above configuration files, the ThinkPHP7 framework can be personalized to meet development needs.

3. Routing settings

In the ThinkPHP7 framework, routing mainly refers to matching access requests with corresponding controller methods. Routing can be divided into static routing and dynamic routing. Static routing refers to directly specifying the mapping relationship between URLs and controller methods, while dynamic routing matches URLs through regular expressions.

In the ThinkPHP7 framework, the routing configuration file is located in the route.php file in the config directory. By modifying the routing rules in this file, access requests can be assigned to the corresponding controller methods.

4. Controller and model

In the ThinkPHP7 framework, the controller mainly defines various business logic in the project, including receiving requests, processing business logic, and calling the corresponding model. Data manipulation. The model is the part that handles data operations, including data query, insertion, update, and deletion operations.

Controllers and models are written in the form of classes in the ThinkPHP7 framework. In the controller, you need to inherit the Controller base class in the framework and implement the corresponding methods. In the model, data manipulation methods are implemented by inheriting the Model base class in the framework.

5. View page

The view page refers to the HTML page. In the ThinkPHP7 framework, it can be implemented through the view template. View templates are usually written in PHP language and contain HTML tags and code for interacting with controllers.

In the ThinkPHP7 framework, the view template is located in the view directory of the project. View templates can be better managed and maintained through corresponding file classification storage.

6. Summary

Through the above introduction, this article introduces in detail how to use the ThinkPHP7 framework for PHP development. Among them, you need to build a framework, configure it, set routing rules, write controllers and models, and use view templates to complete page rendering, etc. I believe that through this article, readers can have a deeper understanding of the ThinkPHP7 framework and better develop PHP projects.
