base.php文件，找不到以下代碼

在putenv("$item=$v");

是：

require __DIR__ . '/library/think/Loader.php';

// 注冊自動加載

Loader::register();

// 注冊錯誤和異常處理機制

Error::register();

// 實現日志接口

if (interface_exists('Psr\Log\LoggerInterface')) {

? ? interface LoggerInterface extends \Psr\Log\LoggerInterface

? ? {}

} else {

? ? interface LoggerInterface

? ? {}

}

// 注冊類庫別名

Loader::addClassAlias([

? ? 'App'? ? ? => facade\App::class,

? ? 'Build'? ? => facade\Build::class,

??? }
}

找到thinkphp目錄下的base.php文件，找到以上代碼

在putenv("$item=$v");

后面加一句

$_ENV[$item]=$v;

這樣將配置文件中的數組賦值給$_ENV數組即可
