A minimal PSR-11 compliant container. Automatically resolves dependencies when possible.

Install

composer require exan/container

Usage

$container = new Exan\Container();

$someClass = $container->get(SomeClass::class);

This will try to instantiate an instance of SomeClass for you and returns it. If you then request this class again further on, it will return the same instance.

Assuming no unresolvable dependencies, it will also resolve nested dependencies.

class SomeClass
{
    public function __construct(public readonly Dependency $dependency)
    {
        // ...
    }
}

$container = new Exan\Container();

$someClass = $container->get(SomeClass::class);

SomeClass in this example will be instantiated with an instance of Dependency.

It can also handle interfaces, but will not be able to resolve an implementation of said interface automatically. You will need to register an entry manually.

interface SomeInterface
{
    // ...
}

class SomeClass implements SomeInterface
{
    // ...
}

$container = new Exan\Container();

$container->register(SomeInterface::class, new SomeClass())

$someClass = $container->get(SomeInterface::class);

Note: it does not automatically resolve primitive types like string and int.
