lib-di-container

A simple implementation of PSR-11: Container.

Description

lib-di-container is a lightweight PHP library that provides a simple implementation of the PSR-11 Container interface. It allows you to manage and retrieve objects and dependencies in your applications.

Features

• Implements the PSR-11 Container interface.
• Supports object instantiation and retrieval.
• Provides dependency injection and method invocation.

Installation

You can install lib-di-container via Composer:

composer require uid/lib-di-container

Usage

Creating a Container

To create a new container, instantiate the Container class:

use Uid\Utils\Container\Container;

$container = new Container();

Defining Services

You can define services in the container using the set method. Services can be defined as anonymous functions or class names:

// Define a service as an anonymous function
$container->set('myService', function ($container) {
    return new MyService();
});

// Define a service as a class name
$container->set('myService', 'MyService');

Retrieving Services

To retrieve a service from the container, use the get method:

$myService = $container->get(MyService::class);

Invoking Methods

The container allows you to invoke methods on objects using the invoke method. You can specify the object and method to invoke, along with any required parameters:

$result = $container->invoke($myService, 'someMethod', ['param1' => $value1]);
