PHP Luminova: Core Custom Service Layer Autoloading Class

Core Services in the Luminova Framework provide a foundational layer for implementing various business logic and functionalities within your application. These services offer versatility, enabling the retrieval of a shared instance of a class, reinitialization of a class with new arguments, or caching and serializing class instances for seamless utilization throughout your application or by third-party modules.

Class Definition

• Class namespace: \Luminova\Base\CoreServices
• This class is an Abstract class
• This class implements: \Luminova\Interface\ServicesInterface, \Luminova\Interface\LazyInterface

Methods

newService

Add a service class to the service autoloading.

 protected static final function newService(string $class, ?string $alias = null,  bool $shared = true,  bool $serialize = false,  array $arguments = []): true

Parameters:

Return Value:

true - Returns true if the service was added successfully, otherwise throws an exception.

Throws:

• \Luminova\Exceptions\RuntimeException - If the service already exists or class argument is not an array list.

Examples

Service Registration

To register a class that should be discoverable in service, you must configure your class in service configuration folder located at /app/Config/Services.php.

Additionally, enable the service feature by setting feature.app.services = enable in your environment configuration file.

namespace App\Config;

use \Luminova\Base\CoreServices;
use \Some\Class\Foo\YourServiceClassName;

class Services extends CoreServices
{
  public function bootstrap(): void
  {
    static::newService(
      YourServiceClassName::class, // Class name to register.
      null, // Class name alias (defaults to the class basename if null).
      true, // Should return shared instance.
      true, // Should serialize and store the class object.
      [] // Initialization arguments, must be array list (int keys)
    );
    //...
  }
}

Once you are done with class registrations, you can now access class anywhere using global helper function service or Service instance to call your class method in service.

Using global helper function

Calling class method with the service alias if specified during class registration.

<?php 
service('example')->doFoo();

Calling class method directly from the class namespace string.

<?php 
service(SomeClass::class)->doFoo();

Using service instance

Optionally class your service from service class static instance.

<?php 
use \Luminova\Application\Services;
Services::example()->doFoo();

Calling or initializing class with namespace is not supported when you use service static method.

Re-Initialization

To re-instantiate class with new constructor arguments is simple, to do that you will need to pass the required values to service method after the first parameter which is always the calling service.

Additionally, to prevent updating the previously stored instance, set the serialize argument to false, also set shared to false if you don't want to return a shared instance.

Examples

Don't share instance nor don't serialize.

<?php 
service('example', false, false, 'param1', 'param2')->doFoo();

Share instance, but don't don't serialize.

<?php 
service('example', true, false, 'param1', 'param2')->doFoo();

Using service instance is a bit difference in term of how it accept your arguments.To directly call service using the service class object, you mus specify serialize or shared as the last 2 arguments after your initialization arguments. Example the order should follow Service::foo(arg1, arg2, serialize, shared).

<?php 
use \Luminova\Application\Services;
Services::example('Peter', 'PHP', false, false)->doFoo();

Share instance but don't serialize.

<?php 
use \Luminova\Application\Services;
Services::example('Peter', 'PHP', false, true)->doFoo();

Optionally you can initialize service from factory, using global function factory to initialize service and call your class method in service.

<?php 
factory('services')->example()->doFoo();

Using factory instance.

<?php 
use \Luminova\Application\Factory;
Factory::services()->example()->doFoo();

Using factory instance.

<?php 
use \Luminova\Application\Factory;
Factory::service(true, false)->example('Peter', 'PHP')->doFoo();
