Perl is one of the most popular scripting languages for adding powerful interactive features to Web pages. Perl lets you place forms on your site that collect and process user input such as comments and product orders; enables visitors to search for information; and can integrate a database into your site, among its many other capabilities. Perl and CGI for the World Wide Web, 2nd Edition: Visual QuickStart Guide fully revised and updated since its original 1998 release, gets users to the core of CGI scripting with Perl. Even first-time programmers will be able to create useful, workable scripts from scratch, or adapt and customize existing scripts to their own needs. Hundreds of screen shots and clear, easy-to-understand directions make this the perfect Perl book for beginners, as well as a handy reference for those with previous programming experience.
