提问by cyber8200
I have a phpscript locate at the rootdirectory of my laravel project. I want to access my settings in my .env
我在Laravel 项目的根目录中有一个php脚本。我想在我的 .env 中访问我的设置
I've tried
我试过了
$dbname = env('DB_DATABASE');
$user = env('DB_USERNAME');
$host = env('DB_HOST');
$pass = env('DB_PASSWORD');
I got
我有
PHP Fatal error: Call to undefined function env()
What is the workaround for that ? Should I include anything to be able to access env()?

If you just want to load your .envconfig in a separate PHP script, you can do it like this:
如果您只想.env在单独的 PHP 脚本中加载您的配置，您可以这样做：
require_once "vendor/autoload.php";
Dotenv::load(__DIR__);
This will load your .envconfig into the $_ENVarray.
这会将您的.env配置加载到$_ENV数组中。
So now you can access your variables like this:
所以现在你可以像这样访问你的变量：
$dbname = $_ENV['DB_DATABASE'];
$user = $_ENV['DB_USERNAME'];
$host = $_ENV['DB_HOST'];
$pass = $_ENV['DB_PASSWORD'];
If you really want that env()helper function, just go get that file:
如果你真的想要那个env()辅助函数，就去获取那个文件：
require_once "vendor/laravel/framework/src/Illuminate/Foundation/helpers.php";
And now you can also access env('DB_DATABASE');
现在您还可以访问 env('DB_DATABASE');
Note: this does NOT give you a bootstrapped Laravel environment at all. It's a simple way to grab your .envconfig variables, but that's it.
注意：这根本不会给你一个引导的 Laravel 环境。这是获取.env配置变量的简单方法，仅此而已。

Laravel is using vlucas/phpdotenvto read the .envfile. The env()function is Laravel helper / shortcut. To use the env command you have to require the vendor files and create an app / kernel laravel object
Laravel使用vlucas / phpdotenv来读取.env文件。该env()功能是 Laravel 助手/快捷方式。要使用 env 命令，您必须需要供应商文件并创建一个应用程序/内核 laravel 对象
<?php
require __DIR__.'/vendor/autoload.php';
$app = require_once __DIR__.'/bootstrap/app.php';
$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);
\Dotenv::load($app->environmentPath(), $app->environmentFile());
var_dump(env('DB_DATABASE'));

This is simple working solution as of 2018/ Laravel 5.6
这是2018/ Laravel 5.6 的简单工作解决方案
//assumes this script is in the root folder, same as .env
require_once "vendor/autoload.php";
(new \Dotenv\Dotenv(__DIR__))->load();
$count = $_ENV['UNICORN_COUNT'];
Troubleshooting:
- make sure Dotenv file is correctly called.
- check the Dotenv->load()(and Dotenv->__constructor()) and supply the needed params.
故障排除：
- 确保正确调用 Dotenv 文件。
- 检查Dotenv->load()（和Dotenv->__constructor()）并提供所需的参数。

With newest version of DotEnv, use this to use the env()function
使用最新版本的 DotEnv，使用它来使用该env()功能
require_once "vendor/autoload.php";
$dotenv = Dotenv::create(__DIR__); // Dir where your .env file is located
$dotenv->load();

Had the same issue for me once fixed by below code
通过以下代码修复后对我有同样的问题
require_once dirname($_SERVER['DOCUMENT_ROOT'])."/vendor/autoload.php";//fetch the document path and removes the public folder using diranme function
$dotenv= Dotenv::create(dirname($_SERVER['DOCUMENT_ROOT']));// Dir where your .env file is located
$dotenv=$dotenv->load();
$url=$dotenv["APP_URL"];
