Laravel is a free, open-source PHP web framework, created by Taylor Otwell and intended for the development of web applications following the model–view–controller (MVC) architectural pattern.

Lumen is a new project from Laravel creator Taylor Otwell. It's a "micro-framework", meaning it's a smaller, faster, leaner version of a full web application framework. It competes other popular micro-frameworks, Slim and Silex.

Middleware provide a convenient mechanism for filtering HTTP requests entering your application. For example, Laravel includes a middleware that verifies the user of your application is authenticated. If the user is not authenticated, the middleware will redirect the user to the login screen. However, if the user is authenticated, the middleware will allow the request to proceed further into the application.
Of course, additional middleware can be written to perform a variety of tasks besides authentication. A CORS middleware might be responsible for adding the proper headers to all responses leaving your application. A logging middleware might log all incoming requests to your application.
There are several middleware included in the Laravel framework, including middleware for authentication and CSRF protection. All of these middleware are located in the app/Http/Middleware directory.

DB::update('update users set city_id = 10 where id = ?', [1015]);

PHP

You may access the current application environment via the environment method.

$environment = App::environment();
dd($environment);

If they haven't used other frameworks, that's OK. If they answer that they haven't used other frameworks then it's important to dig deep into these questions. If they have used other frameworks, ask about the differences and see if they are passionate about Laravel or just have jumped on the bandwagon.

On one hand, all optional components of Laravel (Cashier, Dusk, Valet, Socialite, etc.) do use semantic versioning. However, the Laravel framework itself does not. The reason for this is because semantic versioning is a "reductionist" way of determining if two pieces of code are compatible. Even when using semantic versioning, you still must install the upgraded package and run your automated test suite to know if anything is actually incompatible with your code base.

Answers to this question is NO.Laravel application’s are 100% secure (depends what you mean by “secure” as well), in terms of things you can do to prevent unwanted data/changes done without the user knowing.
Larevl have inbuilt CSRF security, input validations and encrypted session/cookies etc. Also, Laravel uses a high encryption level for securing Passwords.

With every update, there’s the possibility of new holes but you can keep up to date with Symfony changes and security issues on their site.
