<?php

Route::get('/{category}/{slug}-{id}', 'ArticleController@show');


class ArticleController
{
      // public function show($category, $slug, $id)
    public function show($id)
    {
        //
    }
}

2.php

Route::get('/{category}/{slug}-{id}', 'ArticleController@show');

3.php

Route::get('/{category}/{slug}-{id}', 'ArticleController@view')

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Arr;

class RouteArgumentsFilterMiddleware

    {
        $config = config('route.filters');

        if (Arr::has($config, $request->route()->getName())) {
            foreach (Arr::get($config, $request->route()->getName()) as $argument) {
                $request->route()->forgetParameter($argument);
