内容説明

Sams Teach Yourself CGI in 24 Hours teaches you the next step beyond simple HTML Web pages. This new edition covers implementing CGI with both C and Perl, and it discusses CGI's relative strengths and weaknesses in comparison with other Web programming technologies like JavaScript, Java, and PHP. The book takes you from the basics of CGI--learning, for example, how to implement and customize existing CGI programs that have been written by others--to the point where you can use CGI to create your own programs from scratch. The book also provides numerous real-life examples of CGI scripts, such as database search tools, survey forms, interactive games, order forms, guest books, and more.
