Slim is a PHP micro framework that helps you quickly write simple yet powerful web applications and APIs.
Practical guide Slim3 framework. In these tutorials, we cover up all basic of a slim framework functionality like Routing, Controller, Middleware, API etc. we also Cover Basic form handling, page navigation, database connectivity, and complete CURD operation.
<?php
// All required dependency
require('vendor/autoload.php');
// Create instance of slim app
$app = new \Slim\App;
// Basic Routing
$app->get('/',function(){
echo 'Hello World!';
});
// Run Instance of Slim App.
$app->run();
?>
<?php
// All required dependency
require('vendor/autoload.php');
// Create instance of slim app
$app = new \Slim\App;
// Basic Routing
$app->get('/',function(){
echo 'Hello World!';
});
// Create Middleware to handle user request
$app->get('/users',function(){
echo 'users';
});
// Create Middleware to handle posts request
$app->get('/posts',function(){
echo 'posts';
});
// Run Instance of Slim App.
$app->run();
?>
Slim uses a dependency container to prepare, manage, and inject application dependencies.
<?php
require('vendor/autoload.php');
$app = new \Slim\App;
$container = $app->getContainer();
$container['myapp'] = function(){
return 'Hello World! from the Container';
};
$app->get('/',function(){
echo $this->myapp;
});
$app->run();
?>
<?php
require('vendor/autoload.php');
$app = new \Slim\App;
$container = $app->getContainer();
$container['view'] = function ($container) {
$view = new \Slim\Views\Twig(__DIR__ .'/resourses/views', [
'cache' => 'false'
]);
$router = $container->get('router');
$uri = \Slim\Http\Uri::createFromEnvironment(new \Slim\Http\Environment($_SERVER));
$view->addExtension(new Slim\Views\TwigExtension($router, $uri));
return $view;
};
$app->get('/',function($request, $response){
return $this->view->render($response, 'home.twig');
});
$app->run();
?>
