Topics include: Perl basics and language tutorial; Perl Scripts; Variables; Arrays; Associative arrays; Flow control; File I/O with Perl; Pattern matching and regular expressions; Perl for formatted text database reports; Overview of Perl modules and CPAN; CGI and Web development tutorial with Perl (including using HTML forms); Perl and XML; Perl/Tk.
The only one-stop resource for Web developers and programmers. This book is an indispensable resource for Web developers and programmers who program CGI applications in Perl. It is designed to function as both a comprehensive reference to the fundamentals and a hands-on tutorial with detailed examples on creating and customizing CGI applications for the Web. Readers learn how to set up a server for integrating CGI scripts, how to work with HTTP variables, and other important CGI basics. They get a complete review of all the Perl syntax needed to create CGI programs and learn how to upload and test scripts and how to use libraries effectively. The book begins with an overview of CGI fundamentals and shows you how to set up a server for integrating CGI scripts. Hanegan then offers detailed coverage of Perl, including all the syntax for CGI programs. He also shows you how to upload and test perl scripts.

In addition, you'll find coverage of perl modules, functions, regular expressions, CGI programming and programming the SQL database interface via the DBI perl module. Perl Weekend Crash Course shows you how to embed Perl within an Apache server and it includes a CD-ROM that provides you with all the code and auxiliary files, pre- and post-assessment software to evaluate the user's progress, and other value-added software. Topics include: Getting and Installing Perl; An Overview of the Perl Language; The Very Basics of Perl; Using Text Editors; Basics of Perl Programming Style; Scalar Data; List and Hash Data; Statements and Expressions; Operators; Basic Input and Output; Control Structures; Perl Native Functions; Advanced Input and Output: File Manipulation; Directory Manipulation.
It's more than a little bit intimidating to take on the task of writing an intermediate-to-advanced-level book on the subject of World Wide Web programming. The current level of innovation and the rate at which new ideas and techniques are being implemented on the Web is nothing less than exponential. Each new idea or new technique has the potential for adding to or enhancing the vast structure that already is the Web, or refining that structure, making it potentially less cumbersome and easier to understand. Some ideas are adopted as standards, and others fizzle and die lonely little deaths, for lack of use or interest. Keeping up with this process and attempting to deliver a book that will give you, the reader, a feel for which of these ideas and techniques seems to be the most usable, safe, and powerful, is what this book is all about. Topics: A Perl5 Overview and Tutorial; Security on the Web; HTML Forms; Client-Side Perl; Advanced CGI.
A guide to writing CGI applications with Perl, showing how to accomplish everyday tasks necessary for online operations. Includes line-by-line code explanations, examples, and skill-stretching exercises. Also covers working with HTML, web forms, obtaining user input, cookies, tracking clicks, and access countries, using the mod_perl Apache module, connecting to a POP3 server for e-mail, Perl DBI and databases on the Web, tying a hash to a database, embedding Perl in HTML with HTML::Mason, remote file management via the Web, creating dynamic images, XML and its derivatives: RSS and RDF. Two longtime Perl programmers show how the CGI scripting language can accomplish the tasks needed for many online applications. Each chapter covers a specific Web-based application and explains the code line by line (or block by block). Includes an introductory overview for users new to CGI or Perl and numerous appendicies include handy references.
