Les contenus des fichiers

.env.example

# Database info
DB_NAME="databasename"
DB_USER="username"
DB_PASSWORD="password"
DB_CHARSET="utf8"
DB_HOST="db.3wa.io"

composer.json

{ 
	"autoload": 
	{ 
		"classmap": 
			[ 
				"controllers/", 
				"managers/", 
				"models/", 
				"services/"
			] 
	}, 
	"require": 
	{ 
		"vlucas/phpdotenv": "^5.6",
		"twig/twig": "^3.0"
	}, 
	"require-dev": 
	{ 
		"symfony/var-dumper": "^7.0" 
	} 
}

Puis faire la commande

composer install

index.php

<?php

// charge l'autoload de composer
require "vendor/autoload.php";

// charge le contenu du .env dans $_ENV
$dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
$dotenv->load();

controllers/AbstractController.php

abstract class AbstractController
{
    private \Twig\Environment $twig;
    
    public function __construct()
    {
        $loader = new \Twig\Loader\FilesystemLoader('templates');
        $twig = new \Twig\Environment($loader,[
            'debug' => true,
        ]);

        $twig->addExtension(new \Twig\Extension\DebugExtension());

        $this->twig = $twig;
    }

    protected function render(string $template, array $data) : void
    {
        echo $this->twig->render($template, $data);
    }
}

managers/AbstractManager.php

abstract class AbstractManager
{
    protected PDO $db;

    public function __construct()
    {
        $connexion = "mysql:host=".$_ENV["DB_HOST"].";port=3306;charset=".$_ENV["DB_CHARSET"].";dbname=".$_ENV["DB_NAME"];
        $this->db = new PDO(
            $connexion,
            $_ENV["DB_USER"],
            $_ENV["DB_PASSWORD"]
        );
    }
}

.gitignore

vendor/
.env
composer.lock

Puis les commandes suivantes :

git add .gitignore
git commit -m "add gitignore"
git push

Créez ensuite un fichier .env avec les véritables informations de connexion à votre base de données :

# Database info
DB_NAME="databasename"
DB_USER="username"
DB_PASSWORD="password"
DB_CHARSET="utf8"
DB_HOST="db.3wa.io"
