<?php

use Illuminate\Http\Request;
Use App\Article;

Route::get('articles', function() {
    // If the Content-Type and Accept headers are set to 'application/json', 
    // this will return a JSON structure. This will be cleaned up later.
    return Article::all();
});
 
Route::get('articles/{id}', function($id) {
    return Article::find($id);
});

Route::post('articles', function(Request $request) {
    return Article::create($request->all);
});

    $article = Article::findOrFail($id);
    $article->update($request->all());

You are running serve from the root of your project? is /api the route folder?

Does php artisan tinker work?

Have you looked in the Laravel log files?

what error are you getting. can you show ?

@snapey my laravel project name is api. and I have developing some api with laravel and above mentioned my api.php file in routes folder. not tinker command working same result.

Hello, Flex! How did you install PHP on your system? Did you add PHP to your Windows path variable? Are you running "php artisan serve" on the root folder of your project?

@diegoaurino yes I have install php correctly. and My other laravel projects are working fine. this problem is only with this project.

@gorakhyadav no any error on the command prompt

Try to remove your vendor folder and reinstall it. Also, check your artisan file and compare it with the Laravel's default.

@diegoaurino did its but not success

Sorry about that, @flex ! I guess we can try something like "php -S localhost:8000 -t public/" on the root folder of your project, so we can see if the PHP's built-in web server can boot.

If tinker is not working also, then probably other commands like php artisan route:list is also broken?

Did you check the log files as suggested?

Normally this type of problem is where you have introduced an issue in a service provider. If you use GIT go back and check what you have changed lately
