Apache rewrite - get original URL in PHP

Question

I have a rewrite in nginx or Apache for this address:

http://domain.com/hello

to a script like

http://domain.com/test.php&a         


        

Answer 1

In Nginx conf, we need to add user header with request_uri:

proxy_set_header request_uri $request_uri;

And read it in php:

echo $_SERVER['HTTP_REQUEST_URI'];

upd

for some reason nginx don't like symbol '_' in header name, don't know how it worked before, maybe something changed after nginx update. Now i'm using

proxy_set_header rewriteduri $request_uri;

and in php

$_SERVER['HTTP_REWRITEDURI']
