GET variables

[edmon]

Hi,
can i change GET variable in HTTP_GET_VAS.
i can\'t explain well. here is example what i want :
i have page with several checkbox, radio buttons ... and i use them to generate
SQL query.
I want on result page to have link wich change only one of the HTTP_GET_VARS.
like this :
first i have:
http://www.asel.com/asyrsi.php?z3=3&z4=4&r=&grad=&hme=&pe=0&b.x=46&b.y=7

and i want to generate links on result page with URL like this:

1.http://www.asel.com/asyrsi.php?z3=3&z4=4&r=&grad=&hme=&pe=1&b.x=46&b.y=7
2.http://www.asel.com/asyrsi.php?z3=3&z4=4&r=&grad=&hme=&pe=2&b.x=46&b.y=7

i.e. to change value only for \'pe\' and to keep other values the same.

Is this possible?

Thanks
