我一直在使用 symfony/console 来创建命令并像这样注册它们，一切正常：

垃圾箱/控制台：

#!/usr/bin/env php
<?php
require_once __DIR__ . '/../vendor/autoload.php';

use App\Commands\LocalitiesCommand;
use Symfony\Component\Console\Application;

$app = new Application();
$app->add(new LocalitiesCommand(new LocalitiesGenerator()));
$app->run();

src/Commands/LocalitiesCommand.php：

<?php

declare(strict_types=1);

namespace App\Commands;

use App\LocalitiesGenerator;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;


final class LocalitiesCommand extends Command
{
    protected static $defaultName = 'app:generate-localities';

    public function __construct(private LocalitiesGenerator $localitiesGenerator)
    {
        parent::__construct();
    }

    protected function configure(): void
    {
        $this
            ->setDescription('Generate localities.json file')
            ->setHelp('No arguments needed.');
    }

    protected function execute(InputInterface $input, OutputInterface $output): int
    {
        $this->localitiesGenerator->generateJsonLocalities();
        $output->writeln("File localities.json generated!"); …

I started a project using composer and donlowaded the package vlucas/phpdotenv. I would like to call the $_ENV['name'] for example in my whole project without needing to instantiate the dot env in every class like that:

$dotenv = Dotenv::createImmutable(__DIR__);
$dotenv->load();

How can I achieve that like a laravel framework does for example?

Another question is I tough I needed to import my autoload require __DIR__.'/../vendor/autoload.php'; in order to call use Dotenv\Dotenv;...

我如何在类中使用 Dotenv 而不需要自动加载？

编辑添加index.php：

<?php

use Dotenv\Dotenv;

require …
