Development $HTTP_REFERRER / URLs with GET variables

Can anyone tell me if it's possible to get $HTTP_REFFERER to ignore anything after the ? in a url?

i.e. /page.php?ID=1 would become /page.php?

TIA.

EDIT: Sorted now with

PHP:

$from = substr($_SERVER['HTTP_REFERER'], 0, 45);

I should read php.net more often .

 

Yeah you should, but that's probably the wrongest way to do it that I can think of.

May I suggest parse_url()?

 

I also need to learn/remember how to spell referer! Thanks for the tip Linear, I'll stick that in place of my bodged code tomorrow.
