Create a portal using the Yii framework

With the development of Internet technology, portals have attracted more and more attention. Portal website is a basic network application. It mainly provides information services and integrates multiple functional modules, such as news, forums, communities, e-commerce, etc. It has good user experience and efficient data management capabilities. It is an important part of today's An essential application form in the information age.

It is very important to choose an efficient, simple and easy-to-use framework when developing a portal website. This article introduces the Yii framework, an efficient PHP framework, which has the following advantages when developing portals:

1. High speed: The Yii framework uses high-performance Caching technology to cache frequently accessed data and As a result, the response speed of the website is improved.

2. Security: The Yii framework has built-in multiple security layers, including input verification, output filtering, authorization and identity verification, etc. to ensure the security of the website.

3. Ease of use: The Yii framework has a clear and simple architecture and adopts the MVC pattern, allowing developers to easily manage website code and databases.

Below we will take the development of a portal website as an example to introduce the application of Yii framework.

Step One: Environment Setup

The Yii framework requires the environment PHP version >=5.4 and supports MySQL database. In this article, the environment we use is Apache2.4 PHP5.6 MySQL5.7.

After installing the corresponding software, you need to download the Yii framework code and extract it to the WEB directory. The platform is available on the Yii official website.

Step 2: Create Yii Application

In this step, we will create a Yii application renamed "demo". Creating a Yii application is very easy, just execute the following command:

$ cd /path/to/webroot

$php/ yii

$ ./yii startapp demo

In this way, an application named demo will be generated in the webroot directory. Among them, the command php/yii is the command to install Yii in the current directory, and can be changed according to the actual situation.

Step 3: Deploy code and database

After creating the Yii application, you need to deploy the core code of the website and related database scripts. In this example, we deploy the code to the webroot/demo directory. In this directory, we will create the following document structure:

.
├── assets
├── commands
├── components
├── config
├── controllers
├── mail
├── models
├── runtime
├── tests
├── vendor
└── views

In the config folder, we need to configure the relevant parameters of the website, including database connection information, user authentication information, URL routing rules, etc. Relevant settings need to be made in the config/main.php file.

Step 4: Write the controller

In the Yii framework, the controller (Controller) is responsible for processing user requests and sending the results to the view (View). We need to create a Home controller to handle the home page request of the website. The code is as follows:

namespace appcontrollers;
use Yii;
use yiiwebController;

class HomeController extends Controller{

public function actionIndex(){
    return $this->render('index');
}

}

In the above code, we define a HomeController controller and implement its actionIndex method. This method will access the homepage of the website and render the view index.php.

Step 5: Write the view template

In the Yii framework, the view template (View) is the core part used to display the final web page. We need to write a homepage template for the website. In the demo/views directory, we create a template file named index.php with the following code:

<meta charset="UTF-8">
<title>Demo</title>

<h1 id="Hello-World">Hello World!</h1>

In this example, we simply A Hello World sentence is output. In actual development, we can write corresponding HTML code according to needs to achieve the functions required by the website.

Step Six: Access the Portal

Now, we have completed the development of the Yii portal. To access the website, you can point the domain name to the WEB directory where the website is located and enter the following address:

http://localhost/demo/

When accessing the website, the Yii framework will automatically call The actionIndex method of the HomeController controller and renders the corresponding view template.

Summary

Through the above steps, we have completed the process of creating a portal using the Yii framework. The Yii framework has a clear architecture and simple code, providing developers with a more efficient portal development solution. If you are looking for an easy-to-use, efficient, and secure PHP framework to develop your own portal, then the Yii framework is a good choice.
