问题描述

我正在使用 header()将var user 从一页传递给另一页，如下所示:

I'm using header() to pass var user from one page to another as:

header( "Location: temp.php? user = $user" );

该变量被传递，并显示在另一页的url上.

the variable is getting passed and is shown on the url of another page.

但是我不知道如何在该页面中使用这些var user .请帮忙.

But i dont know how to use these var user in that page. Please help.

推荐答案

如果其他页面"在PHP中，则只需要:

if the 'other page' is in PHP, you only need to:

$user=$_GET['user'];

如果不确定是否会收到用户"，并且希望避免出现错误消息，则应该执行以下操作:

If you are not sure if you will receive 'user' and want to avoid error messages you should do:

if(isset($_GET['user'])){
    $user=$_GET['user'];
}else{
    //user was not passed, so print a error or just exit(0);
}
