phpMyAdmin访问出错,session_write_close()出错

很久没有phpMyAdmin了，登陆时出现了以下的问题：

Warning: session_write_close() [function.session-write-close]: open(D:/PC_websever/phproot/session/sess_17064d421eed05a3386f958e07a06ab6, O_RDWR) failed: No such file or directory (2) in D:/PC_websever/phproot/phpmyadmin/index.php on line 44

Warning: session_write_close() [function.session-write-close]: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (D:/PC_websever/phproot/session) in D:/PC_websever/phproot/phpmyadmin/index.php on line 44

此问题是：php.ini 配置文件----->session.save_path = "D:/PC_websever/phproot/session"

解决方法：在相应的目录下找不到"session"文件夹，所以session_write_close()写才会错。
