Very SIMPLE question about VARIABLES !!!

[marconi8]

ok, my variables i check so

if(isset($REQUEST['start_reg'])){$start_reg=$REQUEST['start_reg'];}

but i have more than for instance 50 variables, i don't want to create for each variable new string like

if(isset($REQUEST['var2'])){$var2=$REQUEST['var2'];}
if(isset($REQUEST['var3'])){$var3=$REQUEST['var3'];}

how can i check all my 50 variables in one string ???🙂))

thanks,
