README

This component allows to register services in DI with the settings file.

The main features of the component:

• Services can be initialized with a string, object or service provider;
• Services are connected via a configuration file;
• Services can be registered as "shared" services;

Requirements:

• PHP 5.4
• Phalcon Framework

Phalcon framework: http://phalconphp.com/

Using

For registration services necessary to execute the code:

$services = new Ini('services.ini');
$dic = new FactoryDefault();

$registrant = new Registrant($services);
$registrant->setDi($dic);
$registrant->registration();

Configuring Services

There are three ways to register services:

1. By the class name. This method does not allow to pass arguments to a constructor or adjust parameters.

   [response]
   string = "Phalcon\Http\Response"

2. Registering an instance directly. When using this method the container is placed dependency already finished object.

   [request]
   object = "Phalcon\Http\Response"

3. Through the service provider. Which must implement the interface GetSky\Phalcon\AutoloadServices\Provider. According to the plan, providers are intermediaries for registration of anonymous functions in the container dependency, but have the opportunity to realize any other way that supports Phalcon.

   [route]
   provider = "RouteProvider"

For the second and third method possible to specify which arguments are passed to the constructor and invoke methods since its inception and prior to placement in the DI. Below is an example of how it can be implemented on the ini:

[first-service]
provider = "SomeNamespace\FirstClass"
arg.0.service = "config"
arg.1.var = "24"
arg.2.di = 1
arg.3.s-service = "shared-service"
arg.4.object.object = "SoeNamespace\SecondClass"
arg.4.object.arg.0.var = "42"
arg.4.object.call.0.method = "run"

In the above example, we register the service SomeNamespace\FirstClass under the name first-service and pass 5 arguments: the service config, variable 24, DI (object implements DiInterface), service shared-services caused by the method getShared and an instance of SomeNamespace\SecondClass, which was first created with transfer 42 and calling run.
