in reply to Display the data passed from php
Are the contents of the perl script displayed in the browser, insted of its output? If that's the case, you have a problem with the configuration of your webserver, not with perl.
And a general hint: to ease debugging of CGI scripts, start them with
#!/usr/bin/perl use warnings; use strict; use CGI::Carp qw(fatalsToBrowser);
And print the header as soon as you can.
