Hi,

The module CGI has to be used for cgi like

 
           use strict;
           use CGI;

           # You have to get the zip filename from the form elements o
+f an HTML page using the cgi->param method

           my $cgi = new CGI;
           my $zipName = $cgi->param('Zipfilenm');

           # the Archive::Zip methods can be used here with the $zipNa
+me as the parameter and I guess the global parameter ($opt_h) is for 
+the option of the command line processing of the file , hence can be 
+avoided and need not  like use Getopts::Std and avoid error processin
+g with ARGV , but choose to process errors in the form where you get 
+the zipName and stuff , then   you should be all set
