ThinkPHP is a PHP-based Web application development framework that is widely used in the development of various websites. If you are a PHP beginner and want to master ThinkPHP, then this article will introduce you in detail how to enter ThinkPHP.
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 introduce how to configure 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. After the installation is complete, run the server and access localhost. You can see the default web page running the server.
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. Install configuration files
ThinkPHP framework has many configuration files, including database configuration, routing information configuration, etc. You can copy the default configuration file application.example.conf in the thinkphp directory and name it application.conf.
4. Test environment setup
After configuring the development environment, you can verify whether ThinkPHP is successfully installed and configured by writing a simple test page. Create a new index.php file in the server root directory and write the following code:
define('APP_PATH', './Application/'); define('APP_DEBUG', true); require './thinkphp/ThinkPHP.php';
Then, access localhost/index.php in the browser. If successful, it will 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
The controller is the C (Controller) layer in MVC. It is used to control the relationship between the view and the model and handle application logic. In ThinkPHP, controller code is stored in the controller directory in 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, the model can use ORM technology or directly use SQL statements for data query and operation. The model code is stored in the model directory in the application directory.
3. View
View is the V (View) layer in MVC, which is used to generate the final output template. In ThinkPHP, view files are usually stored in the view directory in the application directory. Developers can use template engines such as Smarty and Twig for view rendering.
4. Routing
Routing is a URL address mapping technology used to map requests to corresponding controllers and methods. In ThinkPHP, you can use routing configuration files to define and map URL address rules. Routing configuration files are stored in the config directory in the application directory.
4. Practical Operation
Before learning the framework, start with simple practical operation and 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 $data;
}</p>
<p>}</p>
<p>2. Create a view file</p>
<p>Create a view file named index.html in the application/view directory. In the template of the view file, you can use {$name} to reference the data defined in the controller method and display it in the view. </p>
<p><!DOCTYPE html><br><html><br><head></p>
<pre class="brush:php;toolbar:false"><meta charset="utf-8">
<title>Hello ThinkPHP</title><h1>Hello {$name}</h1>
