okeyaki/pimple-di

Integrates DI functionality with Pimple.

Pimple DI

Pimple DI integrates DI functionality with Pimple., _(*1)

Features

• Integrating DI (constructor Injection) functionality with Pimple.
• Easy to use.

Installation

Add okeyaki/pimple to your composer.json:, _(*2)

$ composer require okeyaki/pimple-di

Usage

At first, create a sub-class of Pimple\Container and mixin Okeyaki\Pimple\DiTrait:, _(*3)

class Container extends \Pimple\Container
{
    use \Okeyaki\Pimple\DiTrait;
}

Then, create an instance of the class:, _(*4)

$container = new Container();

Constructor Injection

Pimple DI resolves dependencies automatically by the classes of constructor parameters:, _(*5)

class Foo
{
}

class Bar
{
    private $foo;

    public function __construct(Foo $foo)
    {
        $this->foo = $foo;
    }

    public function foo()
    {
        return $this->foo;
    }
}

$foo = $container[Foo::class];

$bar = $contaienr[Bar::class];
$bar->foo();

Class Binding

You can bind classes to an existing ID:, _(*6)

class Foo
{
}

$container['foo'] = function () {
    return new Foo();
};

$container->bind(Foo::class, 'foo');

$foo = $container[Foo::class];

This is useful on using Silex proprietary or third-party providers., _(*7)

Instanciation

You can instanciate a class and resolve its dependencies automatically:, _(*8)

class Foo
{
}

class Bar
{
    private $foo;

    public function __construct(Foo $foo)
    {
        $this->foo = $foo;

        $this->name = $name;
    }

    public function foo()
    {
        return $this->foo;
    }
}

$bar = $container->make(Bar::class);
$bar->foo();

If a constructor has unresolvable parameters:, _(*9)

class Bar
{
    private $foo;

    private $baz;

    public function __construct(Foo $foo, $baz)
    {
        $this->foo = $foo;

        $this->baz = $baz;
    }

    public function foo()
    {
        return $this->foo;
    }

    public function baz()
    {
        return $this->baz;
    }
}

$bar = $container->make(Bar::class, [
    'baz' => 'baz',
]);

$bar->foo();
$bar->baz();

Examples

Integrating with Silex

class App extends \Silex\Application
{
    use \Okeyaki\Pimple\DiTrait;
}
