What is the benefit of using namespaces in PHP?

Namespaces solve the following problems:

• Name conflicts: Allow the use of the same names for classes, interfaces, functions, and constants in different parts of an application or when using third-party libraries, avoiding collisions.
• Code organization: Group related code elements, increasing readability and maintainability.
• Autoloading: Simplify the implementation of class autoloading using PSR-4 or PSR-0 standards by linking namespaces with the file structure.

Example of usage:

<?php

// Namespace for one part of the application
namespace App\Models;

class User {
    // ...
}

// Namespace for another part of the application
namespace App\Controllers;

class UserController {
    // ...
}

Without namespaces, the classes User and UserController could have the same name, which would lead to an error.
