Global vars in URL

[Anon]

I have a little problem:
15,000 lines of PHP code with URLs like
echo "<a href=/blah.php?x=$x(...)";
and other normal hrefs outside of PHP area.
we made a co-branding deal and the other side requests that the variable stating that a page is co-branded or not must be in the URL and not in a cookie. I hate to edit all the code. Is there any other fix for that?
Thanks,
Tomek

If I were in Windows would use and editor like HomeSite 4.5 and use regular expressions to do a sitewide find-and-replace.

Otherwise grep.
