Method for removing statement at end of new url on logout

[PineSmokes]

Trying to figure out how, when I press my logout button, do I get my page to go back to it's original page without the ?variable=something at the end:

header('Location: '.$_SERVER['PHP_SELF'].'?activationsent=1');

Main issue is I'm using this header page to display my login and signup with code and all so I had to change the header("Location lines from permanent to self, when they were permanent that was how I was going back to the "main" page (wiping the statement variable away).  Since my new method to make it universal directs to self it always keeps those variables I used to drop which in turn leaves up messages I wish weren't there sometimes.

I didn't think I had explained it properly the first time,  hopefully there is enough information to find any sort of solution, thanks.

Does it seem like a good idea at all to place a variable on every page with the link to itself that way in the header I can use the variable I set on the page that loaded the header, I could make it a session variable even $_SESSION['url'] then call it like:

header('Location: '.$_SESSION['url'].'?activationsent=1');

Seems to be working fine, guess I solved this one by myself today
