composer如何在php中正确加载库

我正在使用两个库：

• phpdotenv
• spatie/async

这就是我正在执行的：

<?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 SpatieAsyncPool;
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 = DotenvDotenv::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，我得到的错误是：

[2022-08-04 10:38:38]本地。信息：空间\异步\输出\并行错误：PHP注意：未定义的索引：中的DB_HOST/第12行php上的var/local/entopia/config/DataConfigEntropia.php注意：中的未定义索引：DB_USER/第13行php上的var/local/entopia/config/DataConfigEntropia.php注意：未定义的索引：中的DB_PASS/第14行php上的var/local/entopia/config/DataConfigEntropia.php注意：未定义的索引：中的DB_DBMS/第15行上的var/local/entropia/config/DataConfigEntropia.php

到目前为止，我尝试的是自动加载我的Dataconfig文件，并将其包含在回调函数中。它不起作用。我能做什么？
