警告:session_destroy()？

Question

我试图修复我的登录脚本,在我的localhost它工作但上传到我的在线测试服务器,注销被破坏,我收到此错误:

Warning: session_destroy() [function.session-destroy]: Trying to destroy uninitialized session in htdocs/logout.php on line 17

Warning: Cannot modify header information - headers already sent by (output started at htdocs/logout.php:17) in htdocs/logout.php on line 18

Warning: Cannot modify header information - headers already sent by (output started at htdocs/logout.php:17) in www/htdocs/logout.php on line 34

不太确定是什么导致它,因为它正在我的本地主机上工作,任何想法？

Answer 1

session_start();
session_destroy(); /*or sesion_unset();*/

Answer 2

要使session_destroy工作,必须使用session_start启动会话.
