Php 可以将Laravel立面与独立数据库一起使用吗？

我正在关注这一点，我很好奇是否有可能实现以下目标：

$capsule = new Illuminate\Database\Capsule\Manager;

$capsule->addConnection([
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => 'database',
    'username'  => 'root',
    'password'  => 'password',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
]);

$capsule->setAsGlobal();
$capsule->bootEloquent();

# can Facades be used like this somehow?
var_dump(DB::connection()->getPdo());
var_dump(Hash::make('hash'));

我得到以下错误，这是预期的，因为脚本没有加载任何Facades，但我不确定如何调整工作：

Fatal error: Uncaught Error: Class 'DB' not found

我也尝试了被接受的答案，但仍然没有运气（甚至不确定我是否正确使用了它？）

这给了我以下错误：

Fatal error: Uncaught Error: Call to undefined method Illuminate\Support\Facades\DB::connection()

Fatal error: Uncaught Error: Class 'DB' not found

Fatal error: Uncaught RuntimeException: A facade root has not been set.

向上添加“use DB；”仍然会产生以下错误：

Fatal error: Uncaught Error: Call to undefined method Illuminate\Support\Facades\DB::connection()

Fatal error: Uncaught Error: Class 'DB' not found

Fatal error: Uncaught RuntimeException: A facade root has not been set.

在顶部添加“use Illumb\Support\Facades\DB；”会出现以下错误：

Fatal error: Uncaught Error: Call to undefined method Illuminate\Support\Facades\DB::connection()

Fatal error: Uncaught Error: Class 'DB' not found

Fatal error: Uncaught RuntimeException: A facade root has not been set.

有什么建议吗？还是仅仅因为Facades不能与独立数据库一起使用？

经过这么多的胡闹，我终于明白了

composer.json

    "require": {
        "illuminate/database": "^5.7",
        "illuminate/hashing": "^5.7"
    }

bootstrap.php

require 'vendor/autoload.php';

$app = new Illuminate\Container\Container();
Illuminate\Support\Facades\Facade::setFacadeApplication($app);

$app->singleton('db', function () use ($app) {
    $capsule = new Illuminate\Database\Capsule\Manager;

    $capsule->addConnection([
        'driver'    => 'mysql',
        'host'      => 'localhost',
        'database'  => 'database',
        'username'  => 'root',
        'password'  => 'password',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
    ]);

    $capsule->setAsGlobal();
    $capsule->bootEloquent();

    return $capsule;
});

$app->singleton('hash', function () use ($app) {
    return new Illuminate\Hashing\HashManager($app);
});

class_alias(Illuminate\Support\Facades\DB::class, 'DB');
class_alias(Illuminate\Support\Facades\Hash::class, 'Hash');

index.php

require '../bootstrap.php';

var_dump(DB::connection()->getPdo());
var_dump(Hash::make('password'));
