Attribute Container

An attribute based container for league/container.

Installation

Via Composer

composer require kbondurant/attribute-container

Requirements

The following versions of PHP are supported by this version.

• PHP 8.0
• PHP 8.1

Usage

This container allows you to bind an interface to its implementation using PHP Attributes

Add AttributeContainer as a delegate container to your league/container

<?php 

declare(strict_types=1);

$container = new League\Container\Container();
$delegate  = new Kbondurant\AttributeContainer\AttributeContainer();

$container->delegate($delegate);

Regular binding

<?php

declare(strict_types=1);

namespace Tests\Fixtures;

use Kbondurant\AttributeContainer\BindTo;

#[BindTo(Bar::class)]
interface Foo
{
    //
}

Singleton binding

<?php

declare(strict_types=1);

namespace Tests\Fixtures;

use Kbondurant\AttributeContainer\BindTo;

#[BindTo(Bar::class, true)]
interface Foo
{
    //
}

Custom binding attribute

If you do not want to rely on the provided BindTo attribute you can create your own attribute class that implements BindingAttribute interface

#[Attribute]
class MyBindingAttribute implements Kbondurant\AttributeContainer\BindingAttribute
{
    /**
     * @param class-string $class
     */
    public function __construct(
        private string $class,
    ) {
    }

    public function getClass(): string
    {
        return $this->class;
    }

    public function isShared(): bool
    {
        return false;
    }
}

#[MyBindingAttribute(Bar::class)]
interface Foo
{
    //
}
