PHP redirect user through .htaccess and pass requested URL to php?

Question

Say I'm trying to access:

mysite.com/foo/bar/

I want too:

RewriteEngine On
RewriteCond %{REQUEST_URI} !=/index.php
RewriteRule .* /index.php

Then:

$url = $_SERVER['PHP_SELF'];
echo $url;

To show:

foo/bar/

Currently getting:

index.php

(Obviously I have no idea, but you get the point for what I'm trying to achieve)

Answer 1

Use $_SERVER['REQUEST_URI']
