ThinkPHP6 is an MVC architecture framework based on the PHP language. It is an excellent PHP framework chosen by many developers. It has very high performance, ease of use, and rich scalability, which can well meet the needs of various applications. If you want to learn PHP development or are looking for an excellent PHP framework, ThinkPHP6 is not to be missed. This article will introduce readers to the basic knowledge and quick programming methods of ThinkPHP6 from an entry-level perspective.
1. Environment preparation
Before starting to use ThinkPHP6 for development, you need to install and prepare some pre-environment:
First you need to install the PHP environment. You can download the PHP package from the PHP official website: https://windows.php.net/download/. When downloading, choose the version that matches your system and the web server you are targeting, such as Apache or Nginx. You can use comprehensive software packages such as XAMPP or WAMP, or you can install it manually.
Composer is a dependency management tool for PHP that can automatically download and manage framework and library dependencies. You can download the Composer package from the Composer official website: https://getcomposer.org/download/, and then install it according to the instructions.
Use Composer for automated installation. Just open it in the terminal and execute the following command:
composer create-project topthink /think tp6
After the installation is completed, we can access it on the local server and view the effect.
2. Basic knowledge
The directory structure of ThinkPHP6 is similar to other MVC frameworks. You can use the following directories when making initial contact. Understand:
This is the main directory of the application, mainly used to store controllers, models, view files, etc.
This is the configuration directory of the application, which stores all the configuration information of the application.
This directory stores the public resource files of the application, such as CSS, JavaScript, images, etc.
This directory stores the routing configuration file of the application. By default, routing is automatic, but we can also configure manual routing.
ThinkPHP6 uses the MVC (Model-View-Controller) design pattern, where M refers to the model related to database data operations, and V refers to the view related to user interaction, and C refers to the controller that handles requests and responses.
In ThinkPHP6, all requests are accessed through URLs. URL is composed of protocol, domain name, path, file name, parameters, etc., while routing refers to the process of matching URL with controllers and methods. Routing can be set manually, or you can use the automatic routing mode to directly access the corresponding controller and method through the parameters of the URL.
3. Programming Example
The following is a simple programming example, which contains a controller and some simple view files.
In the controller we can define many different processors, such as processing form submission, querying and inserting into the database. The following is an example of a controller named Index:
namespace appcontroller;
class Index
{
public function index()
{
