Don't use ftp.pl. The first sentence in that file states:

This library is no longer being maintained, and is included for backward compatibility with Perl 4 programs which may require it.

Instead, check out Net::FTP or LWP.

Here is an example stolen from Net::FTP documentation: 

       use Net::FTP;
       $ftp = Net::FTP->new("some.host.name", Debug => 0);
       $ftp->login("anonymous",'-anonymous@');
       $ftp->cwd("/pub");
       $ftp->get("that.file");
       $ftp->quit;

As for your next question...

I need to put this into the web, how do I integrate the file into website or what CGI should I write to execute(trigger) this program
... you're going to need to be more specific in describing exactly what you want to do.

If all you want to do is show a file from an FTP site when a user clicks on a link, consider linking directly to the file on that FTP site. Browsers know how to do FTP. 

<a href="ftp://some.host.name/pub/that.file">click here</a>

If the FTP site requires a username and password and you don't mind letting the whole world know what they are, use: 

<a href="ftp://username:password@some.host.name/pub/that.file">click h
+ere</a>
