Minimal, Lightweight, and Fast PHP Dependency Injection Container

Installation

composer require abdelrhmansaid/container

Testing

composer test

Usage

The methodologies of the container are based on the Dependency Injection paradigm, using the ReflectionClass to get class dependencies.

To use the container, you must first create a new instance of the container.

use AbdelrhmanSaid\Container\Container;

$container = new Container();

Or just use the static method Container::getInstance(), that will return the globally available container if it exists, or create a new one.

$container = Container::getInstance();

After you have created the container, you can bind your dependencies to the container.

$container->bind(Foo::class);

Also, you can create a singleton, that will be returned every time you call the get method.

$container->singleton('foo', function () {
    // ...
});

Singletons are useful for classes that are expensive to instantiate, but only need to be created once.

To get a dependency from the container, you can call the make method.

$foo = $container->make('foo');

The main difference between make and get is that make accepts a second parameter, which is an array of parameters to pass to the constructor of the class, while get does not because of implementing PSR-11

By the way you can also create an alias for a class, so you can call it with a different name.

$container->alias(Foo::class, 'bar');

Auto-wiring

Don't worry about the auto-wiring, the container will do it for you.

$container->make(BrandNewClass::class);

It will automatically bind the dependencies of the class, and if the class has a constructor, it will pass the dependencies to it, also the container can inject specific method dependencies using the call method.

$container->call([Foo::class, 'setBar'], ['bar' => $bar]);

And that's it! Enjoy ✌.
