ZF2: how do I get ServiceManager instance from inside the custom class

Question

I\'m having trouble figuring out how to get ServiceManager instance from inside the custom class.

Inside the controller it\'s easy:

$this->getServiceL         


        

Answer 1

Make your custom class implement the ServiceLocatorAwareInterface.

When you instantiate it with the ServiceManager, it will see the interface being implemented and inject itself into the class.

Your class will now have the service manager to work with during its operations.

getServiceLocator();
        $logger = $sl->get( 'My\CusomLogger')
    }
}

// later somewhere else
$mine = $serviceManager->get( 'My\MyClass' );

//$mine now has the serviceManager with in.

Why should this work?

This works only in the context of the Zend\Mvc, which I assume you're using because you mentioned a controller.

It works because the Zend\Mvc\Service\ServiceManagerConfig adds an initializer to the ServiceManager.

$serviceManager->addInitializer(function ($instance) use ($serviceManager) {
    if ($instance instanceof ServiceLocatorAwareInterface) {
        $instance->setServiceLocator($serviceManager);
    }
});

Give it a try and let me know what happens.
