LARAVEL MVC

Mastering MVC

• MVC Framework: Separates an application into three components: Model, View, and Controller.
• Benefits: Separation of logic and presentation, code reusability, code maintainability, faster development.
• Popular MVC Frameworks: ASP.NET, Django, Ruby on Rails, Laravel.
• Laravel: PHP framework with expressive syntax, high security, and web artisan focus.

Laravel Trivia

Laravel is a popular MVC framework known for its elegant syntax and powerful features. It was created by Taylor Otwell in 2011. Laravel follows the Model-View-Controller (MVC) architectural pattern, making it easy to develop and maintain web applications. It has a vibrant community and a rich ecosystem of packages and libraries. Laravel's tagline is 'The PHP Framework for Web Artisans'.

Mastering MVC

• Views blade templating - a simple and powerful templating engine
• @auth - UI for authenticated user
• @guest - UI for guest (Login or Register UI)
• Validation - ensuring data correctness before updating or adding to the database
• Eloquent ORM - a powerful database abstraction layer

Validation

Trivia: Validation is an essential component of the MVC framework. It ensures data correctness before updating or adding to the database. By validating user input, it helps prevent errors and maintain data integrity. Validation rules define the criteria for acceptable data, such as required fields, data types, and length limits. It plays a crucial role in enhancing the overall reliability and security of the application.

Mastering MVC with Laravel Eloquent ORM

• Laravel Eloquent: An ORM that simplifies database interactions
• Eloquent Relationships: Supports various relationships like One To One, One To Many, Many To Many, etc.
• Getting Started with Laravel: Install Composer, Node JS, Text Editor, and Xampp Server
• Creating New Application: Use composer create-project command
• Laravel File Anatomy: Understand the structure of app, config, database, public, resource, routes, and vendor folders
• .env: Configuration file for the application
• Running the Application: Use php artisan serve command and open browser at http://127.0.0.1:8000

Laravel Eloquent:

To simplify database interactions. Laravel Eloquent is an ORM (Object-Relational Mapping) that provides a simple and elegant way to interact with databases.
