What is the main task and the advantages of using Eloquent ORM in Laravel development?

Eloquent ORM in Laravel is an object-relational mapper that allows working with the database through objects and models, rather than writing SQL queries directly. The main goal of Eloquent is to simplify database interactions, making the code more readable and maintainable.

Advantages of using Eloquent ORM:

• Convenience and readability: data operations are performed through model methods, which makes the code understandable.
• Automatic relationship management: easy to work with relationships between tables (one-to-one, one-to-many, many-to-many).
• Protection against SQL injection: ORM automatically escapes parameters.
• Built-in capabilities for pagination, sorting, and filtering.

Example of using Eloquent:

// Get all users
$users = User::all();

// Find a user by ID
$user = User::find(1);

// Create a new user
$user = new User;
$user->name = 'Ivan';
$user->email = 'ivan@example.com';
$user->save();

// Get all posts of the user (one-to-many relationship)
$posts = $user->posts;
