Service

ICanBoogie/Service provides means to reference, resolve, and invoke services using your favorite dependency injection container, in the most transparent way possible.

Please, consider the following example:

<?php

use ICanBoogie\Service\ServiceProvider;
use function ICanBoogie\Service\ref;

ServiceProvider::define(function ($id) {

	if ($id === 'hello')
	{
		return function ($name = "world") {
			return "Hello $name!";
		};
	}

	throw new \LogicException("Unknown service: $id");
});

# getting a service through the provider
$service = ServiceProvider::provide('hello');
echo $service("Madonna");
// Hello Madonna!

# using a reference
$reference = ref('hello');
echo $reference;
// hello
echo $reference("Madonna");
// Hello Madonna! 

References are callables

Service references created with ref are especially useful when you need to provide a callable but you don't want that callable to be instantiated right away:

<?php

use function ICanBoogie\Service\ref;

class Compute
{
	public function __construct(callable $computer)
	{
		// …
	}

	// …
}

$compute = new Compute(ref('expansive_instance'));

References can be exported

ServiceReference instances can safely be exported with var_export():

<?php

use ICanBoogie\Service\ServiceReference;

$id = 'my_service';
$reference = new ServiceReference($id);
$dump = var_export($reference, true);

$r = eval("return $dump;");

echo get_class($r);   // ICanBoogie\Service\ServiceReference 
echo (string) $r;     // my_service
