标头(“位置:/")；重定向适用于本地主机，但不适用于远程服务器 [英] header("Location:/"); redirect works on localhost, but not on remote server

问题描述

if (condition)
{
#lol. Some code here
}
else
{       
header("Location:/");//i'm trying to redirect to the root
}

重定向在本地主机上完美运行，但不适用于远程服务器.使用 $_SERVER 可能更好吗?即使我选择与重定向文件位于同一目录中的文件，此重定向也不起作用.希望你能帮助我:)

Redirect works perfectly on localhost, but not on remote server. May be it's all better to use $_SERVER? This redirect wouldn't work even if i choose file in the same directory as file with redirect. Hope you help me :)

推荐答案

来自手册:

HTTP/1.1 需要一个绝对 URI 作为 » Location 的参数:包括方案、主机名和绝对路径，但一些客户端接受相对 URI.您通常可以使用 $_SERVER['HTTP_HOST']、$_SERVER['PHP_SELF'] 和 dirname() 从自己的亲戚:

HTTP/1.1 requires an absolute URI as argument to » Location: including the scheme, hostname and absolute path, but some clients accept relative URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a relative one yourself:

<?php
/* Redirect to a different page in the current directory that was requested */
$host  = $_SERVER['HTTP_HOST'];
$uri   = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');
$extra = 'mypage.php';
header("Location: http://$host$uri/$extra");
exit;
?>
