How to redirect to the same page in PHP
提问by user710502
How can I redirect to the same page using PHP?
如何使用 PHP 重定向到同一页面？
For example, locally my web address is:
例如，本地我的网址是：
http://localhost/myweb/index.php
How can I redirect within my website to another page, say:
如何在我的网站内重定向到另一个页面，例如：
header("Location: clients.php");
I know this might be wrong, but do I really need to put the whole thing? What if later it is not http://localhost/?
我知道这可能是错误的，但我真的需要把整个事情都放在一起吗？如果以后不是http://localhost/呢？
Is there a way to do something like this? Also, I have a lot of code and then at the end after it is done processing some code... I am attempting to redirect using that. Is that OK?
有没有办法做这样的事情？另外，我有很多代码，然后在处理完一些代码后最后......我正在尝试使用它进行重定向。这可以吗？

There are a number of different $_SERVER(docs) properties that return information about the current page, but my preferred method is to use $_SERVER['HTTP_HOST']:
有许多不同的$_SERVER( docs) 属性可以返回有关当前页面的信息，但我的首选方法是使用$_SERVER['HTTP_HOST']：
header("Location: " . "http://" . $_SERVER['HTTP_HOST'] . $location);
where $locationis the path after the domain, starting with /.
$location域之后的路径在哪里，以/.

My preferred method for reloading the same page is $_SERVER['PHP_SELF']
我首选的重新加载同一页面的方法是 $_SERVER['PHP_SELF']
header('Location: '.$_SERVER['PHP_SELF']);
die;
Don't forget to die or exit after your header();
不要忘记在你的 header(); 之后死亡或退出；

If the query string is also necessary, use
如果还需要查询字符串，请使用
header('Location:'.$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING']);
die;

When htaccess url manipulation is in play the value of $_SERVER['PHP_SELF'] may take you to the wrong place. In that case the correct url data will be in $_SERVER['REQUEST_URI']for your redirect, which can look like Nabil's answer below:
当 htaccess url 操作起作用时， $_SERVER['PHP_SELF'] 的值可能会把你带到错误的地方。在这种情况下，正确的 url 数据将$_SERVER['REQUEST_URI']用于您的重定向，这可能类似于下面 Nabil 的回答：
header("Location: http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
exit;
You can also use $_SERVER[REQUEST_URI] to assign the correct value to $_SERVER['PHP_SELF']if desired. This can help if you use a redirect function heavily and you don't want to change it. Just set the correct vale in your request handler like this:
如果需要，您还可以使用 $_SERVER[REQUEST_URI] 分配正确的值$_SERVER['PHP_SELF']。如果您大量使用重定向功能并且不想更改它，这会有所帮助。只需在您的请求处理程序中设置正确的值，如下所示：
$_SERVER['PHP_SELF'] = 'https://sample.com/controller/etc';

Another elegant one is
另一个优雅的是
header("Location: http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
exit;

To really be universal, I'm using this:
为了真正通用，我正在使用这个：
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off'
|| $_SERVER['SERVER_PORT'] == 443) ? 'https://' : 'http://';
header('Location: '.$protocol.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
exit;
I like $_SERVER['REQUEST_URI']because it respects mod_rewrite and/or any GET variables.
我喜欢，$_SERVER['REQUEST_URI']因为它尊重 mod_rewrite 和/或任何 GET 变量。

A quick easy approach if you are not concerned about query params:
如果您不关心查询参数，一个快速简单的方法：

I just tried using header("Location: ");(without any value) and it redirected to the current page.
我只是尝试使用header("Location: ");（没有任何值）并将其重定向到当前页面。

Simple line below works just fine:

I use correctly in localhost:
我在本地主机中正确使用：
