usually it means you have a wrong path in session.save_pathparameter in Apache config or php.ini

通常这意味着您session.save_path在 Apache 配置或 php.ini中的参数路径错误

try to set

尝试设置

ini_set("session.save_path", "/path/to/tmp");

in the beginning of your file. If it helps, edit your php.ini file, otherwise try to find it somewhere, maybe in VirtualHost section

在文件的开头。如果有帮助，请编辑您的 php.ini 文件，否则尝试在某处找到它，也许在 VirtualHost 部分

ok i have found the solution

好的，我找到了解决方案

 libraries/session.inc.php at line 79  // session.save_handler 
 ini_set('session.save_handler', 'files');

Commenting out this line, everything works fine.

注释掉这一行，一切正常。

You just need to give permission to access this directory.

您只需要授予访问此目录的权限。

On Windows, just open the directory and the system will ask you to change permission to it.

在 Windows 上，只需打开目录，系统就会要求您更改其权限。

Please check code around:

请检查周围的代码：

// optionally set session_save_path
$path = $GLOBALS['PMA_Config']->get('SessionSavePath');
if (!empty($path)) {
    session_save_path($path);
}

You may try commenting it out and test one more time (implementation of session_save_path() is not posted here and I suspect that the issue is there).

您可以尝试将其注释掉并再测试一次（此处未发布 session_save_path() 的实现，我怀疑问题出在那里）。
