1. Learning prerequisites
To learn ThinkPHP, you must first have basic knowledge of PHP, including HTML, CSS, JavaScript and other related knowledge. In addition, you also need to be familiar with the basic operation and use of databases such as MySQL.
2. Environment configuration
Before entering the new development framework, the development environment needs to be configured. The following uses the Windows operating system as an example to explain how to set up the ThinkPHP development environment.
1. Install the Web server
It is recommended to use Apache or Nginx as the local Web server. By installing web server integration software such as WampServer or XAMPP, it is more convenient to install common software such as Apache and MySQL with one click. Once the installation is complete, start the server and visit localhost, it will jump to the server's default web page.
2. Download and decompress ThinkPHP
Visit the ThinkPHP official website, download the latest version of the ThinkPHP framework, and decompress it to the root directory of the server (default: C:\wamp\www), and Name the unzipped folder "thinkphp".
3. Installation configuration files
ThinkPHP framework contains a variety of configuration files, such as database configuration and routing information configuration. You can copy the default configuration file application.example.conf in the thinkphp directory and name it application.conf.
4. Test environment setup
Once the development environment is successfully configured, you can write a simple test page to verify whether ThinkPHP has been installed and configured successfully. Write the following code to create a new index.php file in the root directory of the server:
define('APP_PATH', './Application/'); define('APP_DEBUG', true); require './thinkphp/ThinkPHP.php';
Then, access localhost/index.php in the browser, and if successful, the output "Hello, ThinkPHP" and other information proves that the environment is installed successfully.
3. Infrastructure
ThinkPHP mainly includes controller, model, view, routing and other infrastructure.
1. Controller
In the MVC pattern, the C (Controller) layer is used as a controller, which controls the relationship between the view and the model by processing application logic. ThinkPHP's controller code is located in the controller subdirectory under the application directory. Developers can create multiple controller files as needed.
2. Model
The model is the M (Model) layer in MVC, which is used to process data. In ThinkPHP, data operations can use the model of ORM technology, or you can directly use SQL statements for query and operation. The model code is stored in the "model" directory of the "application" folder..
3. View
View is the V (View) layer in MVC, which is used to generate the final output template. Normally, view files in ThinkPHP are saved in the view folder located in the application directory. Developers can use template engines such as Smarty and Twig for view rendering.
4. Routing
Routing technology is a URL address mapping technology that can map requests to corresponding controllers and methods. ThinkPHP supports the use of routing configuration files to define and map URL address rules. Routing configuration files are stored in the config folder under the application directory.
4. Practical operations
Before learning the framework, start with simple practical operations to learn how to use ThinkPHP to create a simple sample page.
1. Create controller and method
Create a controller named IndexController in the application/controller directory, and create a method named index in the controller. In a method, you can return an array containing the data displayed in the view.
namespace app\controller;
class IndexController
{
public function index() { $data = ['name' => 'ThinkPHP']; return $data; }
}
2. Create a view file
Create a view file named index.html and store it in the application/view directory. In the template of the view file, you can use {$name} to point to the data defined in the controller method and display it in the view.
<meta charset="utf-8"> <title>Hello ThinkPHP</title>
<h2 id="Hello-nbsp-name">Hello {$name}</h2>
3. Routing configuration
Create a routing configuration file named route.php, located in the application/config directory . In this configuration file, you can set routing rules and mappings.
return [
'/index' => 'index/index',
];
4. Access routing
You can start the server and then access it through the browser Access localhost/index to access the sample page. The content of "Hello ThinkPHP" will be displayed on the page.

thinkphp基于的mvc分别是指:1、m是model的缩写,表示模型,用于数据处理;2、v是view的缩写,表示视图,由View类和模板文件组成;3、c是controller的缩写,表示控制器,用于逻辑处理。mvc设计模式是一种编程思想,是一种将应用程序的逻辑层和表现层进行分离的方法。

在thinkphp3.2中,可以利用define关闭调试模式,该标签用于变量和常量的定义,将入口文件中定义调试模式设为FALSE即可,语法为“define('APP_DEBUG', false);”;开启调试模式将参数值设置为true即可。
