Develop a high-performance CMS system using the PHP framework Phalcon-PHP Tutorial-php.cn

With the rapid development of the Internet, the application of CMS (Content Management System) systems is becoming more and more widespread. How to improve the performance and efficiency of CMS systems has become a problem that developers need to solve. It is a very wise choice to use the PHP framework Phalcon for development, because Phalcon itself is a highly optimized and high-performance framework.

Phalcon is a PHP framework written in C language. It is not 100% written in PHP language like other frameworks. Its main code is written in C language. Phalcon is known as one of the fastest PHP frameworks in the world. Its birth benefits from the efficiency of C language, the flexibility of PHP and the huge development community. Phalcon adopts a new way to build the PHP framework, writing the core part in C language and compiling it into a PHP extension, giving it extremely high execution speed and excellent performance, and the way Phalcon is used It is very similar to other PHP frameworks and is very easy to get started.

In the following article, we will introduce how to use the Phalcon framework to build a high-performance CMS system.

Environment setup

Before starting development, we need to set up the running environment of the Phalcon framework in the local environment.
First you need to confirm whether the Phalcon extension is installed in your server. If not, you need to download and install it from the official Phalcon website (https://phalconphp.com/zh/). After the installation is complete, you need to configure the Phalcon extension for the project.

Create directory structure

We need to establish a basic directory structure to organize project files. The Phalcon framework itself adopts the MVC mode, so our directory structure should also follow this structure:

.
├── app
│   ├── config
│   ├── controllers
│   ├── models
│   └── views
├── public
│   ├── css
│   ├── js
│   ├── images
│   └── index.php
├── vendor
└── .htaccess

Save the above code to the project root directory, and place the specific code files in the corresponding directory.
The directory structure can be fine-tuned and adjusted based on specific project requirements.

Writing Controller

The controller is an important part of the Phalcon framework. It is the C (Controller) layer in the MVC model. The controller is responsible for processing from the view layer The request came. We create a file named "IndexController.php" in the "app/controllers" directory, and write some basic controller action methods in the controller:

namespace AppControllers;

use PhalconMvcController;
use PhalconHttpResponse;

class IndexController extends Controller
{
    public function indexAction()
    {
        return $this->response->redirect("index/home");
    }

    public function homeAction()
    {
        return $this->view->render('index', 'home');
    }
}

Copy after login

In the above code, we use Phalcon Some components are provided to implement the basic functions of the controller. Use the "$this->view->render()" method to render the data that needs to be presented to the user.

Writing Model

The model is the M (Model) layer in the MVC pattern, which enables interaction with background data. Create a file named "Article.php" in the "app/models" directory and write some basic code in the model:

namespace AppModels;

use PhalconMvcModel;

class Article extends Model
{
    public function initialize()
    {
        $this->setSource("article_table");
    }

    public static function getAll()
    {
        return Article::find();
    }
}

Copy after login

In the above code, we use the model class "PhalconMvcModel" provided by Phalcon ” to realize the basic functions of the model. Obtain all articles through the "Article::find()" method to realize the interaction between the model layer and the background data.

Writing View Template

View is the V (View) layer in the MVC pattern and is the most common and important part when writing Web applications. Create a file named "index/home.volt" in the "app/views" directory, and write some basic code in the view:

{% extends "index/layout.volt" %}

{% block content %}
    <h1>Welcome to Our CMS System</h1>

    <ul>
        {% for article in articles %}
            <li>{{ article.title }}</li>
        {% endfor %}
    </ul>
{% endblock %}

Copy after login

In the above code, we use "{% extends "index/layout.volt" %}" statement to specify the inheritance relationship of the view. Use the "{% block content %}" and "{% endblock %}" statements to specify dynamic parts.

Writing Routing

Phalcon provides a flexible routing system that allows us to easily define URL routing rules. In "public/index.php", we can implement routing through some simple code, for example:

use PhalconMvcApplication;
use PhalconDiFactoryDefault;
use PhalconMvcView;

$di = new FactoryDefault();

$di->set(
    'router',
    function () {
        $router = new PhalconMvcRouter();
        $router->add('/:controller/:action/:params', array(
            'controller' => 'index',
            'action' => 'index',
            'params' => 1
        ));
        $router->handle();
        return $router;
    }
);

$app = new Application($di);

try {
    $response = $app->handle();
    $response->send();
} catch (Exception $e) {
    echo 'Exception: ', $e->getMessage();
}

Copy after login

In the above code, we define the routing as "/:controller/:action/:params" In this format, the default Controller is "IndexController" and the default Action is "indexAction".

Optimizing configuration

Phalcon provides rich configuration functions, which can perform more detailed configuration tuning of the framework and improve the operating efficiency of the system. We can create a file named "config.php" in the "app/config" directory and write our own configuration information in it. For example:

return new PhalconConfig([
    'database' => [
        'adapter' => 'Mysql',
        'host' => 'localhost',
        'username' => 'root',
        'password' => '',
        'dbname' => 'my_cms_db',
        'charset' => 'utf8'
    ]
]);

Copy after login

In the above code, we configure the database connection and configure some basic parameters of MySQL. Then, load the configuration file in the main program and use the configuration information to initialize some components, such as:

$config = include __DIR__ . "/../app/config/config.php";

$di->set(
    'db',
    function () use ($config) {
        return new PhalconDbAdapterPdoMysql(
            [
                'host'     => $config->database->host,
                'username' => $config->database->username,
                'password' => $config->database->password,
                'dbname'   => $config->database->dbname,
                'charset'  => $config->database->charset,
            ]
        );
    }
);

Copy after login

In the above code, we set the database connection component in "$di" and use it in the configuration file Initialize the component with the configuration information defined in it. In this way, we have completed the development of a high-performance CMS system using the Phalcon framework.

Summary:
