1 - What is the Eloquent ORM and how is it used?
Eloquent is an ORM that allows you to interact with your database more easily by providing an object oriented interface. You can use it to create, read, update, and delete data in your database, as well as perform more complex queries.
2) What is the difference between routing and middleware?
Routing is the process of matching incoming HTTP requests to the appropriate controller actions. Middleware is a way to intercept requests and perform actions on them before they reach the controller actions. Middleware can be used for authentication, authorization, rate limiting, and more.
3) What is the Laravel service container and how is it used?
The Laravel service container is a dependency injection container that allows you to register and resolve services. Services can be anything from simple objects to complex classes. The service container makes it easy to manage dependencies between your classes and to ensure that they are always resolved correctly.
4) What is the Artisan command line tool and how is it used?
The Artisan command line tool provides a number of commands that you can use to interact with your Laravel application. You can use Artisan to create new migrations, models, controllers, and other files. You can also use Artisan to run database migrations, seed your database, and more.
5) What is the Blade templating engine and how is it used?
The Blade templating engine is a powerful tool that allows you to create beautiful and dynamic views for your Laravel applications. Blade provides a number of features, such as conditional statements, loops, and includes, that make it easy to create complex layouts.
6) What is the difference between a view and a template?
A view is a file that contains the HTML code for a specific page in your application. A template is a file that contains the basic structure of your application's pages. You can use Blade to create both views and templates.
7) What is the MVC architectural pattern and how is it used in Laravel?
The MVC architectural pattern is a design pattern that separates your application into three layers: the model layer, the view layer, and the controller layer. The model layer contains the business logic of your application, the view layer contains the HTML code for your application, and the controller layer handles the interaction between the model and view layers.
8) What is the difference between a GET request and a POST request?
A GET request is used to retrieve data from a server, while a POST request is used to send data to a server. GET requests are typically used for retrieving data that is not sensitive, while POST requests are typically used for sending data that is sensitive.
9) What is the difference between a 404 error and a 500 error?
A 404 error is an error that is returned by a server when it cannot find the requested resource. A 500 error is an error that is returned by a server when it encounters an unexpected error.
10) What is the difference between a cookie and a session?
A cookie is a small piece of data that is stored on a user's computer by a web browser. Cookies are typically used to track user information, such as their login status or their shopping cart contents. A session is a server side mechanism for storing user information. Sessions are typically used to store data that is needed for a single user interaction, such as the contents of a shopping cart.
11 - What is the difference between a package and a plugin?
A package is a collection of reusable code that can be installed into your Laravel application. Packages can be used to add new features to your application, such as a payment gateway or a social media integration. A plugin is a smaller piece of code that can be installed into your Laravel application. Plugins are typically used to extend the functionality of a specific package.
12) What is the difference between a service provider and a facade?
A service provider is a class that provides services to your Laravel application. Service providers are used to register services with the service container. A facade is a class that provides a simple way to access services from your Laravel application. Facades are typically used to access services that are provided by service providers.
13) What is the difference between a route and a controller?
A route is a mapping between a URL and a controller action. You can use routes to define the different ways that users can access your application's functionality. A controller is a class that contains the business logic for a specific feature of your application. Controllers are responsible for handling user input and generating the appropriate response.
14) What is the difference between a model and an entity?
A model is a class that represents a real world entity, such as a user or a product. Models typically contain the business logic for a specific entity. Entities are simply data objects that represent a specific piece of data, such as a user's name or a product's price.
15) What is the difference between a relationship and an association?
A relationship is a connection between two models. Relationships can be one to one, one to many, or many to many. Associations are similar to relationships, but they are typically used to describe the relationship between a model and a table in the database.
