Slim vs Phalcon: Micro-framework showdown for small projects

Micro-frameworks are widely used in small projects because They are lightweight and easy to use. In this article, we’ll compare Slim and Phalcon, two popular PHP microframeworks, to help you decide which one is better for your next project.

Slim

Slim is a simple and flexible micro-framework based on the PSR-7 standard. It uses the routing middleware pattern to make creating routes and handling requests simple.

// 创建 Slim 应用
$app = new \Slim\App;

// 定义一个路由
$app->get('/hello/{name}', function (Request $request, Response $response, array $args) {
    return $response->withJson(['message' => 'Hello ' . $args['name'],]);
});

// 运行应用
$app->run();

Phalcon

Phalcon is a full-stack framework that provides all the components needed to build a complete web application. It has built-in ORM, view renderer, and security features.

// 创建 Phalcon 应用
$app = new \Phalcon\Mvc\Application;

// 定义一个路由
$app->router->add('/hello/{name}', [
    'controller' => 'Welcome',
    'action' => 'hello',
]);

// 运行应用
$app->handle();

Practical Case

Suppose we want to create a simple REST API to get a list of users. The following is the code implemented using Slim and Phalcon:

Slim

// 创建 Slim 应用
$app = new \Slim\App;

// 定义一个路由
$app->get('/users', function(Request $request, Response $response) {
    return $response->withJson(['users' => ['user1', 'user2']]);
});

// 运行应用
$app->run();

Phalcon

// 创建 Phalcon 应用
$app = new \Phalcon\Mvc\Application;

// 定义一个控制器
class WelcomeController extends \Phalcon\Mvc\Controller {
    public function helloAction() {
        $this->view->users = ['user1', 'user2'];
    }
}

// 定义一个路由
$app->router->add('/users', [
    'controller' => 'Welcome',
    'action' => 'hello',
]);

// 运行应用
$app->handle();

Conclusion

Slim and Phalcon are both excellent micro-frameworks, but they are suitable for different project types. If you're looking for a simple, lightweight, and easy-to-use framework, Slim is a great choice. If you need a more comprehensive framework with a richer feature set, Phalcon may be a better choice.
