Laravel Reflection

readme.md

This is a simply thrown-together gist to demonstrate an issue I'm having with laravel's service container; for somee reason I'm unable to resolve() classes with mixed typed and numbered constructor arguments. Any idea why this is happening for me?

laravel-reflection.php

<?php
require_once 'vendor/autoload.php';
use Illuminate\Support\Arr;

/**
 * Demo with some reflection, I'm working on this for a project and need 
 * this working or at least a viable workaround very soon, thanks!
 */

class SlackRegistration { }
class SlackMessage {
	public function __construct( $instance, int $notifiable ) {
		dd( func_get_args(), $notifiable, $instance );
	}
}

class Registered {	
	private function reduce(): Closure {
		return function( array $parameters, ReflectionParameter $parameter ) {
			array_push( $parameters, $parameter->getName());
			return $parameters;
		};
	}
	
	private function reflect(): array {
		$frame = Arr::get(debug_backtrace( DEBUG_BACKTRACE_PROVIDE_OBJECT, 2), 0);
		$method = new ReflectionMethod( $this, Arr::Get( $frame, 'function' ));
		
		$prototype = array_reduce( $method->getParameters(), $this->reduce(), array());
		$named = Arr::get( $frame, 'args' );
		
		return array_merge( array_slice( $named, count( $named ) - 1),
							array_combine( $prototype, array_slice( $named, 0, count( $named ) - 1)));
	}
	
	/*
	 * I can't provide numbered arguments that match numbered arguments 
	 * in the object I'm creating's constructor?
	 */
	private function createInstance( string $className, $notifiable ) {
		dump( $this->reflect());
		return resolve( $className, [ 213, 123 ]);
	}
	
	/**
	 * Deliver mail to new members.
	 * 
	 * @param	object	$event
	 * @return void
	 */
	public function handle($event) {
		$this->createInstance( SlackMessage::class, $event->account, resolve( SlackRegistration::class ));
	}
}

$registered = resolve(Registered::class);
$registered->handle(new class {
	public int $account = 0;
});
