All routes and controllers will return a response sent to the user's browser after processing the business logic. Laravel provides a variety of ways to return responses. The simplest is to return a string in the route or controller, and the bottom layer of laravel will automatically create a complete http response to return.
Route::get('index', function () {
return 'study laravel'
});If an array is returned, laravel will automatically convert it to json format for output. In addition, the following code is equivalent:
return ['name' => 'laravel', 'email' => 'laravel@qq.com']; return response(['name' => 'laravel', 'email' => 'laravel@qq.com']); return response()->json(['name' => 'laravel', 'email' => 'laravel@qq.com']);
Add response header
Adding a response header is very simple. You only need to use the header method. You can use multiple header methods to set multiple response headers.
return response('study laravel')
->header('Content-Type', 'text/html; charset=UTF-8')
->header('Php-Version', '7.4');You can also use withHeaders to set multiple response headers at one time. This method accepts an array as the first parameter.
return response('study laravel')
->withHeaders([
'Conetnt-Type' => 'text/html; charset=UTF-8',
'Php-Version' => '7.4'
]);Redirect
In laravel, there are several ways to implement redirection. Can be redirected through Route::redirect or function redirect. Because Route::redirect belongs to routing-related knowledge, here, we look at the redirect function.
return redirect('index/users');
Often, when a form is submitted and verification fails, we will return to the previous form page. Here, we need to use the back function to complete.
return back();
You can also redirect to a named route. If there are parameters in the route, pass it through the second parameter:
return redirect()->route('news', ['id' => 23]);
Often, we will re-direct after performing some logical processing. Directed to another controller to continue the next step. For example, when registering something requires filling in multiple forms.
return redirect()->action('IndexController@index', ['id' => 1]);
Sometimes you need to redirect to a domain name outside the application, you can also use away to complete the operation. It is without any encoding
return redirect()->away('http://google.com');
Other response types
View responses are very common and can be set using the view method
return response()
->view('welcome', $data, 200)
->header("Content-Type", "text/html;charset=utf-8");In addition, laravel also provides download responses, file responses, etc. Since they are not used much in daily work, they will not be introduced here. Interested students can check relevant documents by themselves.

The routing system allows the definition of URL structure and request processing logic. 2.EloquentORM simplifies database interaction. 3. The authentication and authorization system is convenient for user management. 4. The event and listener implement loosely coupled code structure. 5. Performance optimization improves application efficiency through caching and queueing.
Why is Laravel so popular?Apr 02, 2025 pm 02:16 PMLaravel's popularity includes its simplified development process, providing a pleasant development environment, and rich features. 1) It absorbs the design philosophy of RubyonRails, combining the flexibility of PHP. 2) Provide tools such as EloquentORM, Blade template engine, etc. to improve development efficiency. 3) Its MVC architecture and dependency injection mechanism make the code more modular and testable. 4) Provides powerful debugging tools and performance optimization methods such as caching systems and best practices.
Which is better, Django or Laravel?Mar 28, 2025 am 10:41 AMBoth Django and Laravel are full-stack frameworks. Django is suitable for Python developers and complex business logic, while Laravel is suitable for PHP developers and elegant syntax. 1.Django is based on Python and follows the "battery-complete" philosophy, suitable for rapid development and high concurrency. 2.Laravel is based on PHP, emphasizing the developer experience, and is suitable for small to medium-sized projects.
