我正在使用两个库：

• phpdotenv
• spatie/async

这是我正在执行的内容：

<?php
require_once "/var/local/entrop/vendor/autoload.php";
include_once '/var/local/entrop/inc/Functions.php';
include_once '/var/local/entrop/model/Contract.php';

use Spatie\Async\Pool;

try {
    $aConn = Functions::getConnection();
    $contracts = Contract::getContracts();

    $pool = Pool::create();
    
    foreach ($contracts as $contract){
        $pool->add(function () use ($aConn, $contract) {
            include_once '/var/local/entrop/config/DataConfig.php';
            $next_contract = Contract::getNextContract($aConn);
        })
        ->then(function ($output) {
        })
        ->catch(function ($exception) {
            Functions::write_log($exception);
        })
        ->timeout(function () {
            Functions::write_log("timeout");
        });
    }

    await($pool);

    $aConn->close();
}
catch (Exception $e){
    Functions::write_log($e);
}

这是DataConfig的定义：

<?php
ini_set('display_errors',1);
error_reporting(E_ALL); 

require_once "/var/local/entrop/vendor/autoload.php";

$dotenv = Dotenv\Dotenv::createImmutable("/var/local/entrop/");
$dotenv->load();

define('DB_HOST', $_ENV['DB_HOST']);
define('DB_USER', $_ENV['DB_USER']);
define('DB_PASS', $_ENV['DB_PASS']);
define('DB_DBMS', $_ENV['DB_DBMS']);

class DataConfig {
    static $db_host = DB_HOST;
    static $db_user = DB_USER;
    static $db_pass = DB_PASS;
    static $db_dbms = DB_DBMS;
}

这是我的composer.json文件：

{
    "require": {
        "vlucas/phpdotenv": "^5.2",
        "spatie/async": "^1.5"
    },
    "autoload": {
        "classmap": [
            "/var/local/entrop/model/Contract.php"
        ]
    }
}

现在，我遇到的错误是：

[2022-08-04 10:38:38]local.INFO：空间\异步\输出\并行错误： PHP 注意：未定义索引：DB_HOST in /var/local/entropia/config/DataConfigEntropia.php 第 12 行 PHP 注意：未定义索引：DB_USER in /var/local/entropia/config/DataConfigEntropia.php 第 13 行 PHP 注意：未定义索引：DB_PASS in /var/local/entropia/config/DataConfigEntropia.php 第 14 行 PHP 注意：未定义索引：DB_DBMS in /var/local/entropia/config/DataConfigEntropia.php 第 15 行

我尝试的方法是自动加载我的DataConfig文件，并将其包含在回调函数中。但没有起作用。我应该怎么做？
