如何在PHP中重定向到同一页面

Question

How can I redirect to the same page using PHP?

For example, locally my web address is:

http://localhost/myweb/index.php

How can I redirect within my website to another page, say:

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/?

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?

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']:

header("Location: " . "http://" . $_SERVER['HTTP_HOST'] . $location);

where $location is the path after the domain, starting with /.
