Slim and Phalcon microframework performance PK

Slim and Phalcon are close in performance, and their routing and template rendering speeds are similar. However, Phalcon is slightly better at database queries.

Slim and Phalcon micro-framework performance PK

Introduction

Slim and Phalcon is a popular microframework in PHP. Both are lightweight, fast, and capable of building high-performance web applications. In this article, we will compare their performance and provide a practical example to demonstrate their differences.

Benchmarks

We will use benchmark tools to measure the performance of Slim and Phalcon on various tasks. Tasks include:

• Routing
• Database query
• Template rendering

Code sample

Slim

$app = new \Slim\App();

$app->get('/test', function (Request $request, Response $response) {
    $response->getBody()->write('Hello World!');
    return $response;
});

Phalcon

$di = new \Phalcon\DI\FactoryDefault();

$app = new \Phalcon\Mvc\Micro($di);

$app->get('/test', function () {
    echo 'Hello World!';
});

Practical case

Let’s look at a simple construction Practical examples of REST API. The API will have the following endpoints:

• /users: Get a list of all users
• /users/:id: Get a specific user Details

Slim

$app->get('/users', function (Request $request, Response $response) {
    $users = $this->db->select('id', 'name')->from('users')->fetchAll();
    return $response->withJson($users);
});

$app->get('/users/{id}', function (Request $request, Response $response, array $args) {
    $user = $this->db->select()->from('users')->where('id = :id', ['id' => $args['id']])->fetch();
    return $response->withJson($user);
});

Phalcon

$app->get('/users', function () {
    $users = Users::find();
    return new Phalcon\Mvc\Response(['content' => json_encode($users)]);
});

$app->get('/users/{id}', function ($id) {
    $user = Users::findFirstById($id);
    return new Phalcon\Mvc\Response(['content' => json_encode($user)]);
});

Results

The results of benchmark tests and actual cases show that Slim and Phalcon are very close in performance. Routing and template rendering speeds are similar for both. However, Phalcon is slightly better at database querying because it uses PHP's native PDO extension, while Slim uses the third-party Doctrine ORM.

Conclusion

Both Slim and Phalcon are excellent microframeworks for building high-performance web applications. They are easy to use, lightweight, and can be easily extended. The final framework choice depends on the specific needs of the application.
