Getting the full URL page in PHP

[Shovel]

Quickie:

I have a link generated at the bottom of my webpages that links directly into the XHTML validator. However, since my entire website is served up by index.php, I need to include the page variables for my URL in that URL.

Is there a dead easy way to grab the URL, query string intract, and output it like I want.

E.g. If it were this messageboard: I want to generate: "https://forums.freddyshouse.com/newthread.php?do=newthread&f=5" not "https://forums.freddyshouse.com/newthread.php".

Thanks

$PHP_SELF, this is a global variable that should work as long as safe mode is not enabled...

failing that you can just reconstruct the URL that linked to the page with the variables
