美好的一天，我在本地主机wamp服务器上构建的登录脚本在本地主机上运行良好，但是自从将其上传到服务器以来，它一直无法正常运行。它会读取用户名和密码，如果正确，则不执行任何操作，但如果输入错误，则会警告我这是错误的。如果正确，应该将我重定向到主页。自从在服务器上以来，我一直在为此奋斗。请任何将提供帮助的人将不胜感激。我的注册页面也做同样的事情。它注册但不提供任何反馈，也不会重定向到登录页面，但是在localhost上一切正常 登录脚本

答案 0 :(得分：-1)
更改服务器中的PHP版本。它必须类似于本地服务器中的PHP版本
答案 1 :(得分：-1)
我没有任何评论的声誉，所以我将尝试给出答案。
检查您的connection.php文件，并验证主机名等是否正确。
由于未正确设置数据库，很可能无法连接到数据库，因此它将检查您告诉脚本的错误，但不会执行数据库部分（查询）。
答案 2 :(得分：-1)
检查是否已按照与localhost文件夹中相同的方式将文件存储在服务器上。
编辑：
if(isset($_SESSION['use']))
{
header("Location:home.php");
}
这里的变量“ use”是什么？看起来您已经复制了代码，却忘记了更改变量名，这就是为什么它没有重定向到正确的页面。
