README

A PSR-11 compliant container that merges a set of PSR-11 containers. You might call it a container container.

Requirements

Requires PHP 7.1

Installation

Through Composer, obviously:

composer require chrisharrison/merged-container

Why?

The PSR-11 container interface have the following properties:

• It's immutable. That means it can't be changed after it's been instantiated.
• It doesn't provide an iteration mechanism.

These two properties mean it's difficult to create a container which is a merge of two or more PSR-11 containers.

This library provides a container which implements the PSR-11 interface. It's constructed by an array of other PSR-11 containers. These containers can use any concrete implementation (PHP-DI, Pimple) as long as they implement the PSR-11 interface.

Usage

Create a merged container:

$merged = new MergedContainer([$container1, $container2]);

Use it like any other PSR-11 container.
