A lightweight Dependency Injection Container (DIC) for PHP, to manage and streamline object dependencies effectively.
- Lightweight and Efficient: Manage dependencies with ease.
- Flexible Configuration: Easily integrate with various PHP applications.
- PSR-11 Compliance: Ensures interoperability between containers.
- PHP 7.4 or higher
- Composer installed on your system
To include the FlightPHP Container in your project, you can use Composer:
composer require flightphp/container
To use the FlightPHP Container, you can create a new instance of the container and bind your dependencies:
<?php require 'vendor/autoload.php'; use flight\Container; $container = new Container; $container->set(PDO::class, fn(): PDO => new PDO( 'mysql:host=localhost;dbname', 'username', 'password' )); $pdo = $container->get(PDO::class); var_dump($pdo); /* object(PDO)#3 (0) { } */
You can use the FlightPHP Container in your FlightPHP application by setting the container instance:
<?php require 'vendor/autoload.php'; use flight\Container; $container = new Container; $container->set(PDO::class, fn(): PDO => new PDO('sqlite::memory:')); Flight::registerContainerHandler([$container, 'get']); class TestController { private PDO $pdo; function __construct(PDO $pdo) { $this->pdo = $pdo; } function index() { var_dump($this->pdo); } } Flight::route('GET /', [TestController::class, 'index']); Flight::start();
Go and visit that route in your dev server and you'll see something like:
object(PDO)#3 (0) {
}
FlightPHP Container can resolve dependencies recursively, allowing you to bind complex objects and dependencies:
<?php require 'vendor/autoload.php'; use flight\Container; class User {} interface UserRepository { function find(int $id): ?User; } class PdoUserRepository implements UserRepository { private PDO $pdo; function __construct(PDO $pdo) { $this->pdo = $pdo; } function find(int $id): ?User { // Implementation ... return null; } } $container = new Container; $container->set(PDO::class, static fn(): PDO => new PDO('sqlite::memory:')); $container->set(UserRepository::class, PdoUserRepository::class); $userRepository = $container->get(UserRepository::class); var_dump($userRepository); /* object(PdoUserRepository)#4 (1) { ["pdo":"PdoUserRepository":private]=> object(PDO)#3 (0) { } } */
