What is Laravel?

Eloquent ORM:

Laravel's built-in ORM (Object-Relational Mapping) provides a simple and elegant way to interact with the database. It allows developers to work with database records using PHP syntax rather than writing raw SQL queries, and to focus on building their application's logic rather than dealing with low-level database details.

Routing:

Laravel offers a straightforward and expressive syntax for defining routes. This makes it easy to map URLs to specific controllers and actions within your application.

Example route definition using a closure:

Route::get('/hello', function () {
    return 'Hello, world!';
});

Blade Templating Engine:

Blade is Laravel's templating engine, which allows for the creation of dynamic HTML content using simple, readable syntax. Blade simplifies the process of creating and managing the presentation layer of web applications.

Authentication and Authorization:

Laravel comes with built-in authentication and authorization functionalities, making it easier to manage user access and permissions.

Artisan Console:

Artisan is Laravel's command-line interface (CLI), which provides numerous commands to assist in application development. Tasks like database migrations, seeding, and running tests can be handled through Artisan commands.

Example:

php artisan make:controller UserController

Middleware:

Middleware allows filtering of HTTP requests entering your application. It's useful for tasks like authentication and logging.

Queues and Task Scheduling:

Laravel includes support for queuing jobs to perform background tasks asynchronously and a task scheduling system to run scheduled jobs.

Queues

Queues are used to handle tasks such as sending emails, processing uploaded files, or performing any other background tasks that don't need to be executed immediately.

Task Scheduling

Task scheduling is often used to perform maintenance tasks, run background jobs, or execute other routine operations without manual intervention.

Database Migrations and Seeders:

Migrations

Migrations are like version control for your database, allowing you to easily modify and share the application's database schema. Instead of manually modifying the database schema using SQL queries, Laravel migrations allow you to define the changes using PHP code.

Seeders

Seeders allow you to populate your database with sample or default data. They are particularly useful during development and testing phases when you need to have some data in your database to work with.

Testing:

Laravel is built with testing in mind. It includes features for unit testing and integration testing, allowing developers to ensure their applications function correctly.

Ease of Use:

Laravel's syntax is elegant and easy to learn, making it accessible to developers of all skill levels.

Community:

Laravel has a large and active community, providing extensive documentation, tutorials, forums, and packages available through Composer and Packagist.

Security:

Laravel provides built-in security features like protection against SQL injection, cross-site request forgery (CSRF), and cross-site scripting (XSS).

Scalability:

A Laravel applications can be easily scaled, from simple applications to large enterprise-level projects.
