Question

我想在我的网站上为我的一些管理工具创建一个LDAP登录页面，但在使用我获得的一些模板后遇到了问题。我最终选择了一个我认为可以满足我的需求的模板/教程，制作了相应的文件并调整了变量，只是为了在发布后获得Parse error: syntax error, unexpected $end error。我正在寻找一些关于如何使这个项目成功的指导。

session_start();
session_destroy();

if(!isset($_POST['user'])){?>

当您不使用PHP短标签时，问题在http://3v4l.org/UaYh1上得到修复。你能在自己的服务器上试试吗？

使用短标签无论如何都不是一件好事。

解析错误：语法错误，LDAP登录表单上的意外$ end
