将额外（链式）方法调用捕获到__get（）魔术方法中

Question

I don't have high hopes for this one:

Given a service that has an action like the foo in $service->foo->bar( $a, $b ) and a container class that has $service as a protected property, is there a way to use __get() on the container to access the service and pass along the ->bar( $a, $b )?

class Container {
  protected $service;
  protected $responses = [];

  public function __get ($name) {
    $this->responses[] = $service->$name-> _???_
    return $resp;
  }
}

that could be intercepted so that the Container could catch the operation, call $service with it, save the response, then return the response

Either some way to grab whatever else is being chained on the $name or if $name just included all of that. I know this is a little convoluted, but it would help me clean some code up substantially, plus I'm just generally curious now.

This app is running PHP7 if that matters.

And alternately, if there is a way to do this but it isn't __get(), insight would be appreciated

Answer 1

The call to bar takes place after __get returned. __get is called by the engine so you can't add additional parameters. However you can create additional methods on your container class to implement the feature you want.

Assuming I understood your question correctly this would result in something like this:

public function executeOnService(string $name, string $method, ...$args) {
    return call_user_func_array([$this->service->$name, $method], $args);
}
