Zend Framework 2 Override an existing Service?

I am using a zf2 module called GoalioRememberMe and now I want to override its service by my customized service. Or if it is not possible, I want to override the Module.php with my config. Is it possible?

In the Application module. I wrote this line in module.config.php:
'GoalioRememberMe\Service\RememberMe' => 'Application\Service\RememberMe'

Thanks in advance!

Actually the service manager first runs a method "canonicalizeName()" which "normalizes" the names as follows:

  1. All _ / \ and - are stripped out
  2. The key is made lowercase

Thus both "GoalioRememberMe\Service\RememberMe" and "goaliorememberme_rememberme_service" become "goalioremembermeremembermeservice" (i.e. they're both the same), thus the error message.

The quickest way to override an existing service is to create a *local.php or *global.php file in the /config/autoload folder. (That folder is identified in config/application.config.php.) Any override files in this folder are process after modules are loaded. If you have duplicate service manager keys, the last one wins.

As Jurian said, the service name is goaliorememberme_rememberme_service and it has been set in the getServiceConfig() method. So I wrote this code in the Module.php file in the Application Module: 

$serviceManager->
            setAllowOverride(true)->
            setInvokableClass('goaliorememberme_rememberme_service', 'Application\Service\CustomRememberMe')->
            setAllowOverride(false);

And it replaced successfully with my customized service!
Thanks very much to Jurian for the big help!

This is exactly the reason it is recommended to name the service as the type of the object that is returned. The object GoalioRememberMe\Service\RememberMe is named goaliorememberme_rememberme_service in the service manager. You can check that here.

So the solution is simple, instead of this:

'GoalioRememberMe\Service\RememberMe' => 'Application\Service\RememberMe'

Write this

'goaliorememberme_rememberme_service' => 'Application\Service\RememberMe'
