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.
