我有一个适用于 Linux 但不适用于 Windows 的 PHP 脚本。 我可以接受我的 PHP 编码不是很好，我是新手。 我有一个表格，我将数据发布到它。现在它在 Windows 服务器上，我得到:
Notice: Undefined index: nmr in C:\Apache24\htdocs\index.php on line 31 ...
等等。
我尝试将所有变量声明为 0，并使用 isset，但它似乎不起作用。 也许我错误地使用了 isset。有人能帮我吗？

最佳答案
if(isset($_POST['nmr'], $_POST['UName'], ...) {
$reg_wvar=$_POST['nmr'];
$reg_UName=$_POST['UName'];
...
}
