phpfox-service

This library does not support service locator pattern.
All service must be declare in configure explicit.

Service manager is a container which control the way to create an object using their name instead of create them explicit.

There are 4 methods in the container

• has($id): bool
• get($id): mixed
• set($id, $object)
• build($id): mixed
• remove($id): void

In other to configure an object, declare them in module.config.php.

return [
    'services'=>[
        'map'=>[
            'db'=> [null, ServiceClass],
            'db2'=> [ServiceFactoryClass,],
        ]
    ]
]

We support 2 way of $scheme value:

• If the first value is null, the constructor of ServiceClass will be called.
• If the first value is a string, It must implement FactoryInterface, so the factory pattern will be used.

Example

module.config.php

return [
    'services'=>[
        'map'=>[
            'models'=>[null, 'Phpfox\Model\GatewayManager'],
            'other_service'=> [OtherServiceFactory,]
        ]
    ]
]

class OtherServiceFactory {
    function factory($className){
        return new ExampleService();
    }
}

Use class name directly

$models  =  $service->get('models');
echo get_class($models);
//print "Phpfox\Model\GatewayManager"

Use factory class name

$others  =  $service->get('other_service');
echo get_class($others);
//print "ExampleService"

Service Manager is a container, when you call get($id)

• If the first call, they build a service map to $id, then store in their container.
• Call get($id) again, it return the object in its container.
• If you want to create a new instance of $id, call build($id) instead.
