Runner IoC Container

A small IoC Container for PHP

Installation

$ composer require runner/container

Usage

create an instance of the container, and bind services into the container with a name.

basic binding

use Runner\Container\Container;

$container = new Container();

$container->bind('stack', SplStack::class);

$container->make('stack');

$container->bind(ArrayAccess::class, function () {
    return new ArrayObject();
});

binding implementation

use an interface name as name and bind a concrete implementation to it

$container->bind(ArrayAccess::class, function () {
    return new ArrayObject();
});

$container->make(ArrayAccess::class);

binding singleton

$container->bind(
    'db', 
    function () {
        return new PDO();
    }, 
    true
);

$container->bind();

binding instance

just another way to binding singleton

$pdo = new PDO();

$container->instance('db', $pdo);

alias binding

bind an alias as concrete to a registered service

$container->bind(CacheInterface::class, function () {
    return new FileCache();
});

$container->bind('cache', CacheInterface::class, true);

$container->make('cache');

have fun :)

contextual binding

bind different implementation to classes while doing injecting

$container->bind(CacheInterface::class, function () {
    return new FileCache();
});

$container->bind('redis_cache', function () {
    return new RedisCache();
});

$container->bindContext(
    PageController::class,
    CacheInterface::class,
    function (Container $container) {
        return $container->make('redis_cache');
    }
);

$controller = $container->make(PageController::class);
