A It contains configuration files for the application.

B It contains the core application code like models, controllers, and services.

C It holds the database migration files and seeders.

D It stores all the public assets like images, CSS, and JavaScript files.

💡 Hint

What happens if you place a view file outside the 'resources/views' directory?

In Laravel, where should you place your Blade view files for them to be properly loaded? What happens if you put a view file outside the resources/views directory and try to load it?

A The view will load but without any styling or scripts.

B Laravel will automatically search all directories and load the view from anywhere.

C Laravel will not find the view and will throw a "View not found" error.

D Laravel will load the view but cache it in the wrong location.

💡 Hint

Think about how Laravel organizes views by default.

Laravel expects all Blade view files to be inside resources/views. If a view is outside this folder, Laravel cannot find it and throws an error.

Why does Laravel fail to load environment variables?

You moved your Laravel project to a new server, but the app does not load environment variables from the .env file. What is the most likely cause?

A The <code>.env</code> file is missing or not readable by the server.

B The <code>config</code> directory is empty.

C The <code>app</code> directory is renamed.

D The <code>public</code> directory is missing.

💡 Hint

Environment variables come from a special file that must be present and readable.

Laravel loads environment variables from the .env file. If this file is missing or the server cannot read it, the variables won't load.

B Laravel loads the default welcome page.

C Laravel returns a 404 Not Found error.

Think about what happens when Laravel tries to call a method that does not exist.

Laravel tries to call the specified controller method. If it does not exist, it throws a 500 error indicating the method is missing.
