Question

1. Passing parameters into the service?
If not already defined in the services.xml (or yaml), is the only way to pass parameter(s) into service is:

$container->setParameter('loader', $loader);
$container->get('myservice');

I suppose this way loader will be available to ALL services, not just “myservice”?

2. Passing an array of objects into the service?
The Template/DelegatingEngine class takes an array of engine object into the constructor, and I dont know how should I define that in the xml file:

public function __construct(array $engines = array())
    {
        $this->engines = array();
        foreach ($engines as $engine) {
            $this->addEngine($engine);
        }
    }

What should I put into the

<service id="myCustomeFramework.TemplateEngine" class="path\to\DelegateEngine" scope="prototype">
            <argument>how can i pass an array of engines here?</argument>
        </service> 

Answer 1

Answer 1

Yes, it will be available for all services that uses that parameter and that are called after setting the parameter.

Answer 2

For passing an array as an argument to a service using xml you have to do it in this way:

<service id="myCustomeFramework.TemplateEngine" class="path\to\DelegateEngine" scope="prototype">
    <argument type="collection">
        <argument key="key">value</argument>
        <argument key="key">value</argument>
        <argument key="key">value</argument>
    </argument>
</service>
