passing parameters to perl cgi called from within PHP

is it possible to pass a parameter to a perl cgi from within PHP eg exec("/home/sites/site6/web/cgi-bin/test.cgi?p1=fred&p2=joe",$alloutput,$ret urnval); I seem to be having some problems with this - maybe it's on the perl end - just want to make sure I am calling it right first though I believe that $alloutput will be an array containing each line of Print output from the cgi so that I can pass info back to the php script that way i can successfully use the exec but not with the parameters regards Jim Carey
