Yet another dependency injection container for PHP

This is a simple to use, yet powerful service container that provides a seamless way to automate dependency injection featuring auto-wiring and object hydration.

composer require webdevcave/yadic

Alternatively, you can clone the repository or download the source files directly and include them in your project.

Usage

Autowiring

<?php

require_once __DIR__.'/vendor/autoload.php';

use Webdevcave\Yadic\Annotations\Provides;
use Webdevcave\Yadic\Annotations\Singleton;
use Webdevcave\Yadic\ServiceContainer;

interface StorageInterface
{
    public function store(mixed $data): bool;
}

#[Provides('storage')]
#[Provides(StorageInterface::class)]
#[Singleton]
class Storage implements StorageInterface
{
    public function store(mixed $data): bool
    {
        //store data...

        return true;
    }
}

class MyController
{
    public function __construct(
        private StorageInterface $storage
    ) {
    }

    public function save(): bool
    {
        return $this->storage->store('my data...');
    }
}

$container = new ServiceContainer();

//No need to do this in a real world application:
$container->addAlias(StorageInterface::class, Storage::class);

//Use this instead:
//$container->loadDefinitionsFromDirectory($directory, $namespace); //Loads annotations from classes declared in a PSR4 directory
//var_dump($container->get('storage')->store($data));

var_dump($container->get(MyController::class)->save()); //bool(true)

Invoking a method ft. autowiring

$arguments = ['nonInjectableArgument' => 'value']; //optional
$container->invoke([$instance, 'methodName'], $arguments);

Hydration

//Class declarations:

use Webdevcave\Yadic\Annotations\ArrayOf;

class Candidate
{
    public function __construct(
        public ?string $name = null,
        public ?int $age = null,
        #[ArrayOf(Skill::class)]
        public array $skills = []
    ) {
    }
}

class Skill
{
    public function __construct(
        public string $title,
    ) {
    }
}

// Hydration example 1:
$data = [
    'name'   => 'John Doe',
    'age'    => 25,
    'skills' => [
        ['title' => 'PHP'],
        ['title' => 'Java'],
        ['title' => 'Rust'],
        ['title' => 'React'],
    ],
];
$instance = $container->hydrate(Candidate::class, $data);

//Results output
/*
print_r($instance);
This test printed output: 
Candidate Object
(
    [name] => John Doe
    [age] => 25
    [skills] => Array
        (
            [0] => Skill Object
                (
                    [title] => PHP
                )

            [1] => Skill Object
                (
                    [title] => Java
                )

            [2] => Skill Object
                (
                    [title] => Rust
                )

            [3] => Skill Object
                (
                    [title] => React
                )

        )

)

// Hydration example 2:
$data = [
    [
        'name' => 'Foo',
        //...
    ],
    [
        'name' => 'Bar',
        //...
    ]
];
$instances = $container->hydrate(Candidate::class, $data);
//Results output
/*
print_r($instances);
This test printed output: 
Array
(
    [0] => Candidate Object
        (
            [name] => Foo
            //...
        )

    [1] => Candidate Object
        (
            [name] => Bar
            //...
        )
)
