How to extract data from a link?

Question

PHP

You need to get the id parameter from the link: www.domen.ru/test.php#id=123
I know how this is done if GET, but how to be here?
I found only this: parse_url , but it's not clear how to pass a link to it.

Answer 1

javascript.ru/window-location

Answer 2

explode + parse_str
ps.
If getting from the link means getting the hash of the current open page, then this is not PHP.

Answer 3

Is there any information after '#' in $_SERVER{'REQUEST_URI'}?
Or where are you getting this link from.
