很抱歉我的错误解释，我希望你知道我的意思。也许你的问题是，$\u GET[“logout”]变量仍然设置，并且在构造函数中你的类破坏了会话。尝试取消设置所有$\u在使用后获得变量。首先需要检查会话工作。创建twp新php文件，例如test.php、example.php test.php
<?php
/* Get All errors */
ini_set('display_errors', 'On');
error_reporting(E_ALL);
if(session_id() == '') {
session_start();
}
$_SESSION['test'] = 'test';
?>
如果您尝试启动会话的第一行代码，它工作正常？仍然不工作。我认为我的问题是登录的_被初始化为false。然后我尝试在doLogin（）中将其设置为true，但在处理admin.php页面时，它又变回false
