Check out CGI's Dump method, already in there! 
      DUMPING OUT ALL THE NAME/VALUE PAIRS
  
       The Dump() method produces a string consisting of all the
       query's name/value pairs formatted nicely as a nested
       list.  This is useful for debugging purposes:
  
           print $query->Dump

       Produces something that looks like:

           <UL>
           <LI>name1
               <UL>
               <LI>value1
               <LI>value2
               </UL>
           <LI>name2
               <UL>
               <LI>value1
               </UL>
           </UL>

       As a shortcut, you can interpolate the entire CGI object
       into a string and it will be replaced with the a nice HTML
       dump shown above:

           $query=new CGI;
           print "<H2>Current Values</H2> $query\n";

Also, beware! You should HTML-entitize your output, or not use text/html, when you do this.
