Laravel namespaces: what they are and how they work

I namespace in Laravel they are definited as an element class, where each element has a different name than its associated class. 

The keyword use allows us to shorten the namespace. Let's see this example:

namespace App\Models;
 
class File {

    public function TheMethodThatGetsFiles()
    {
    }
}

Namespaces are normally used in controllers

app/controllers/FileController.php

namespace App\Controllers;

use App\Models\File;

class FileController {
    public function someMethod()
    {
        $file = new File();
    }
}

When you put a class in a namespace, to access any of the built-in classes, you need to call them from Root Namespace. 

For example $stdClass = new stdClass(); becomes $stdClass = new \stdClass();

To import others namespace:

use App\Models\File;

This will allow you to use the class File without the prefix namespace.

You have to put the namespace above to easily understand the file dependencies. After that, run the composer dump-autoload. If you want to log in to FileController, it will be necessary defideny route and specify the fully qualified namespace which will redirect it to the specified method of the controller.

Route::get('file', 'App\\Controllers\\FileController@TheMethod');

Declaration of namespace

The keyword use allows developers to shorten the namespace.

use <namespace-name>;

Il namespace predefinito used in Laravel is App, however a user can edit the namespace to match the web application. Creating a namespace deficreated by the user with the artisan command is as follows:

php artisan app:name SocialNet

Il namespace, once created, may include various features that can be used in controller and in various classes.
