PHP Dependency Injection Container

A simple dependency injection container for php projects

composer require njeaner/di-container

Initialize without parameter

$container = new \NJContainer\Container\Container();

Initialize using the parameter

The container can be constructed with:

and NJContainer\Container\InstanceDefinition can be constructed with:

$containerDefinition = new \NJContainer\Container\ContainerDefinition(); $instance = new \NJContainer\Container\InstanceDefinition(); // or $instance = new \NJContainer\Container\InstanceDefinition($containerDefinition); $container = new \NJContainer\Container\Container($instance);

Setting a dependency in the container

/** * @param id string * @param mixed $definition * @param bool $shared, if "true" container will save this definition instance as a factory dependency */ $container->set($id, $definition) $container->set($id, $definition, true)

Setting several definition using an array of definitions

/** * @param $definitions * @example [ * 'name'=> ['John Doe'], * 'stdClass1' => [new stdClass()], * \Namespace\Route::class => [new \Namespace\Route(), true] * ]; * The true value as second item in dependency array means that you are storing an= factory dependency */ $container->add($definitions)

Setting several definition using an file with return an array of definitions

/** * @param string $definitionsPath, path directory of definition file */ $container->addDefinition($definitionsPath)

Setting dependency parameters

Setting a parameter of an alias

/** * @param string $id definition id * @param string $name parameter name * @param mixed $parameter param value to set in definition */ $container->setParameter($id, $name, $parameter)

Setting several parameter of an alias

/** * @param string $id definition id * @param array $parameters */ $container->setParameters($id, $parameters)

Getting a dependency from the container

/** * @param string $id * @param bool $shared, if "true" container with retrieve a factory dependency */ $container->get($id) $container->get($id, true)

class Foo < >class Bar < public function __construct(Foo $foo, $type = 'Bar')< $this->foo = $foo; $this->type = $type > > class FooBar< public function __construct(Foo $foo , string $name, array $params) < >>

# config.php # dependency configuration file  return [ 'name'=> 'John Doe', FooBar::class => get()->setParameters( 'name' => get('name'), 'params' => ['type' => FooBar::class] ) ];

$container = new \NJContainer\Container\Container(); $container->addDefinition('config.php'); $arrayDefinition = [ FooBar::class => get()->setParameters( 'params' => add(['bool' => false]) ) ]; $container->add($arrayDefintion); $container->lock(); $fooObject = $container->get(Foo::class); $barObject = $container->get(Foo::class); // Foo::class and Bar::class has been resolved using autowiring $foobar = $container->get(FooBar::class);

README.md

PHP DI Container resolves dependencies for php application using Dependency Injection. And it provides a simple container for all depnedencies as well. It can take dependencies as argument to other classes and resolve them efficiently. Good thing about container is you can specify dependencies in many formats:

PHP DI Container is capable of reading configuration from above four formats and load them as services to the container using lazy loading using PHP Simple Config While using PHP Simple Config can use cache for our configuration as well to boost the performance. Please go through details about PHP Simple Config.

Future plan is to allow simple php container without any config file for small applications.

Note: Currently its only support PHP version 5.5 and above

Add following dependency to your composer.json

 require:  // Add this line to your `composer require` as shown below "gr8abbasi/php-di-container":"dev-master" > >

Create a configuration file in the desired formate and use desired reader by default service loader will use php config file reader

use Mcustiel\Config\Drivers\Reader\php\Reader as PhpReader; use Mcustiel\Config\Drivers\Reader\ini\Reader as IniReader; use Mcustiel\Config\Drivers\Reader\json\Reader as JsonReader; use Mcustiel\Config\Drivers\Reader\yaml\Reader as YamlReader;

PHP configuration file looks like something below and you can see it contains others classes as dependencies as well.

 return [ 'class-a' => [ 'class' => 'Tests\\DummyServices\\ClassA', ], 'class-b' => [ 'class' => 'Tests\\DummyServices\\ClassB', 'arguments' => [ 'class-a' ] ], 'class-c' => [ 'class' => 'Tests\\DummyServices\\ClassC', 'arguments' => [ 'class-b' ] ], ];

$loader = new ServiceLoader(); $services = $loader->loadServices( __DIR__ . "/Fixtures/phpServicesConfig.php", new PhpReader() ); $container = new Container($services); // To get services from container $service = $container->get('foo');

< "services": [ < "id": "class-a", "class": "Tests\\DummyServices\\ClassA" >, < "id": "class-b", "class": "Tests\\DummyServices\\ClassB", "arguments": [ < "id": "class-a" > ] >, < "id": "class-c", "class": "Tests\\DummyServices\\ClassC", "arguments": [ < "id": "class-a", "id": "class-b" > ] > ] >

$services = $loader->loadServices( __DIR__ . "/Fixtures/jsonServicesConfig.json", new JsonReader() );

SERVICES: class-a: class: Tests\\DummyServices\\ClassA class-b: class: Tests\\DummyServices\\ClassB arguments: class: class-a class-c: class: Tests\\DummyServices\\ClassC arguments: class: class-a class: class-b 

$services = $loader->loadServices( __DIR__ . "/Fixtures/yamlServicesConfig.yml", new YamlReader() );

[SERVICES] class-a.class = Tests\\DummyServices\\ClassA class-b.class = Tests\\DummyServices\\ClassB class-b.arguments = class-a class-c.class = Tests\\DummyServices\\ClassC class-c.arguments = class-a class-c.arguments = class-b

$services = $loader->loadServices( __DIR__ . "/Fixtures/iniServicesConfig.ini", new IniReader() );
