Full analysis of PHP framework: CodeIgniter, Yii, Phalcon, peak showdown

In the world of PHP, frameworks are complex to build Web applications are essential, providing powerful tools and features that help developers improve efficiency and maintainability. In this battle of PHP frameworks, CodeIgniter, Yii and Phalcon come out on top, let’s take a deeper look at their pros and cons and demonstrate their capabilities through practical examples.

CodeIgniter: The lightweight king

CodeIgniter is known for its lightweight and simplicity, making it ideal for small to medium-sized applications. It provides an intuitive syntax that is easy to learn, so even PHP beginners can get started quickly.

Advantages:

• Lightweight: Occups less resources, suitable for deployment to shared hosts
• Simple: Low learning curve, can be mastered quickly even without framework experience
• Flexibility: Allows developers to freely customize the structure of the application

Practical case: Quickly build a blog system

// app/controllers/Blog.php
class Blog extends CI_Controller {
    public function index() {
        $this->load->model('blog_model');

        $data['posts'] = $this->blog_model->get_all_posts();

        $this->load->view('blog_view', $data);
    }
}

// app/models/blog_model.php
class Blog_model extends CI_Model {
    public function get_all_posts() {
        return $this->db->get('posts')->result();
    }
}

Yii: Full-featured monster

Yii is a full-featured framework suitable for various applications applications of varying sizes and complexity. It provides a modular architecture that allows developers to easily extend and customize the functionality of the framework.

Advantages:

• Modularity: Allows components to be loaded on demand, improving performance and flexibility
• ActiveRecord: Provides an elegant object-relational mapping (ORM) system
• Advanced caching: Built-in multiple caching mechanisms to improve application performance

Practical case: Build a RESTful-based API

// app/controllers/api/PostController.php
class PostController extends Controller {
    public function actionIndex() {
        $posts = Post::find()->all();

        return $posts->asArray();
    }
}

// app/models/Post.php
class Post extendsActiveRecord {
    public static function find() {
        return new ActiveQuery(get_called_class());
    }
}

Phalcon: Speed ​​Champion

Phalcon with its ultra-fast execution speed It is well-known for handling high traffic and high concurrency applications. It uses C language extensions to provide native performance while maintaining ease of use.

Advantages:

• Speed: Ultimate performance, suitable for applications that need to process large amounts of data
• Lightweight: Small memory footprint, suitable for deployment in restricted environments
• MVC architecture: Follows the classic MVC architecture, which facilitates code organization and maintenance

Practical case: Create a high-performance shopping website

// app/controllers/ProductController.php
class ProductController extends Controller {
    public function initialize() {
        $this->view->setRenderLevel(\Phalcon\Mvc\View::LEVEL_NO_RENDER);
    }

    public function productsAction() {
        $products = Product::find();

        $this->response->setJsonContent($products->toArray());

        return $this->response;
    }
}

// app/models/Product.php
class Product extends Model {
    public static function find() {
        return new ProductQuery();
    }
}

Summary

CodeIgniter, Yii and Phalcon each have their own advantages and Disadvantages. Choosing the appropriate framework depends on the specific requirements of the application. For lightweight and simple applications, CodeIgniter is a good choice. For applications that are complex and require full functionality, Yii is worth considering. And for applications that require extreme performance, Phalcon is the clear choice.
