What is a Namespace in Laravel?

In PHP, a namespace is a way to group related classes, functions, and constants under a single identifier. 
Namespaces are used to avoid naming conflicts between different classes, functions, and constants and make organizing and managing your code easier. Just as a file with the same name can exist in two separate folders, a class of a specific name can be defined in two namespaces.

The use of namespaces becomes crucial as the project grows. Giving a unique name to each class or function may become tedious and not exactly elegant, and that's when namespaces come in handy.

A namespace is defined using the namespace keyword, followed by the name of the namespace. 

– For example:

<?php
namespace App\Http\Controllers;

class PostsController {
    // 
}
?>
