Use of single module multiple times - php

Question

I have created Auth and Acl modules using zend-framework2, And these two are working good. Now I want to use these modules multiple times with different configuration.
Basically, I have two sections in my project -
User Section
Admin Section
And both have different session variables and different database tables.
I have Auth configuration file as following (module.config.php) -
return array(
'auth' => array(
'db' => array(
'table' => 'user',
'identity' => 'email',
'credential' => 'password',
'credential_treatment' => array(
'class' => '\My\Common',
'method' => 'encrypt'
),
'status' => array(
'is_enabled = true',
),
),
'view' => array(
'label' => array(
'identity' => 'Email',
),
),
'route' => array(
'login' => 'home',
'logout' => 'home',
),
'whitelist' => array(
'home',
)
),
....
....
);
I want to use the same module for both Admin section and User section, But with different configuration settings, Like different database tables and session variables.
Is it possible to do so or I have to create different modules for different section?
Let me know if you need more details.

Here's an simple approach for your use case. I didn't test it, so expect some typos :)
I hope you get the basic idea. If not, let me know.
config/autoload/auth.global.php
return [
'service_manager' => [
'factories' => [
'YourAuthNamespace\Config' => 'YourAuthNamespace\Service\ConfigServiceFactory',
'YourAuthNamespace\AbstractAuthFactoryFactory' => 'YourAuthNamespace\Service\AbstractAuthFactoryFactory',
],
'abstract_factories' => [
'YourAuthNamespace\AbstractAuthFactoryFactory'
]
]
];
src/YourAuth/Service/AbstractAuthFactoryFactory.php
namespace YourAuth\Service;
class AbstractAuthFactoryFactory implements \Zend\ServiceManager\AbstractFactoryInterface
{
public function canCreateServiceWithName(\Zend\ServiceManager\ServiceLocatorInterface $serviceLocator, $name, $requestedName)
{
$key = $this->getConfigKeyFromServiceName($name);
$config = $this->getConfig($serviceLocator);
return array_key_exists($key, $config);
}
private function getConfig(\Zend\ServiceManager\ServiceLocatorInterface $serviceLocator)
{
return $serviceLocator->get('YourAuthNamespace\Config');
}
public function createServiceWithName(\Zend\ServiceManager\ServiceLocatorInterface $serviceLocator, $name, $requestedName)
{
$key = $this->getConfigKeyFromServiceName($name);
$config = $this->getConfig($serviceLocator);
return new YourAuthClass($config[$key]);
}
private function getConfigKeyFromServiceName($name)
{
return preg_replace('#^YourAuthNamespace\Auth\#i', '', $name);
}
}
src/YourAuth/Service/ConfigServiceFactory.php
namespace YourAuth\Service;
use Zend\ServiceManager\FactoryInterface;
class ConfigServiceFactory implements FactoryInterface
{
public function createService(ServiceLocatorInterface $serviceLocator)
{
$config = $serviceLocator->get('Config');
return $config['yourauth'];
}
}
module/MyModuleA/config/module.config.php
return [
'yourauth' => [
'ModuleA' => [ // 'ModuleA' is also the key used by the abstract factory
'db' => [
'table' => 'module_a_auth_table',
// ...
],
'session' => [
'namespace' => 'module_a_session_namespace'
// ...
],
]
],
'service_manager' => array(
'factories' => array(
'MyModuleA\Auth' => function ($sm) {
return $sm->get('YourAuthNamespace\Auth\ModuleA');
}
),
),
];
module/MyModuleA/src/AuthClient.php
namespace MyModuleA;
class AuthClient implements \Zend\ServiceManager\ServiceLocatorAwareInterface
{
public function doSomethingWithAuth()
{
if ($this->getServiceLocator()->get('MyModuleA\Auth')->isAuthorized()) {
// blah...
}
}
}
