Single Action Controllers

If you would like to define a controller that only handles a single action, you may place a single __invoke method on the controller:

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use App\User;

class ShowProfile extends Controller
{
    /**
     * Show the profile for the given user.
     *
     * @param  int  $id
     * @return View
     */
    public function __invoke($id)
    {
        return view('user.profile', ['user' => User::findOrFail($id)]);
    }
}

When registering routes for single action controllers, you do not need to specify a method:

Route::get('user/{id}', 'ShowProfile');

You may generate an invokable controller by using the --invokable option of the make:controller Artisan command:

php artisan make:controller ShowProfile --invokable
