Beginning Perl, 3/e (Paperback)

This is a book for those of us who believed that we didn’t need to learn Perl, and now we know it is more ubiquitous than ever. Perl is extremely flexible and powerful, and it isn’t afraid of Web 2.0 or the cloud. Originally touted as the duct tape of the Internet, Perl has since evolved into a multipurpose, multiplatform language present absolutely everywhere: heavy-duty web applications, the cloud, systems administration, natural language processing, and financial engineering. Beginning Perl, Third Edition provides valuable insight into Perl’s role regarding all of these tasks and more.

Commencing with a comprehensive overview of language basics, you’ll learn all about important concepts such as Perl’s data types and control flow constructs. This material sets the stage for a discussion of more complex topics, such as writing custom functions, using regular expressions, and file input and output. Next, the book moves on to the advanced topics of object-oriented programming, modules, web programming, and database administration with Perl’s powerful database interface module, DBI. The examples and code provided offer you all of the information you need to start writing your own powerful scripts to solve the problems listed above, and many more.

Whether you are a complete novice or an experienced programmer, Beginning Perl, Third Edition offers an ideal guide to learning Perl.

What you’ll learn

• How to use the power of Perl
• How to handle Perl data structures
• How to build database applications regardless of the underlying database
• How to parse complex data
• How to write industrial-strength object-oriented Perl
• How to start web programming in Perl

這是一本針對那些曾經認為不需要學習Perl的人的書籍，現在我們知道Perl比以往更加普及。Perl非常靈活和強大，並且不害怕Web 2.0或雲端。最初被譽為互聯網的「膠帶」，Perl已經演變成一種多用途、多平台的語言，無處不在：重型網絡應用、雲端、系統管理、自然語言處理和金融工程。《Beginning Perl, Third Edition》提供了有關Perl在所有這些任務中的角色的寶貴見解。

從全面概述語言基礎開始，您將學習有關Perl的重要概念，如數據類型和控制流程結構。這些材料為更複雜的主題討論鋪平了道路，例如編寫自定義函數、使用正則表達式和文件輸入輸出。接下來，本書介紹了面向對象編程、模塊、Web編程以及使用Perl強大的數據庫接口模塊DBI進行數據庫管理的高級主題。提供的示例和代碼將為您提供開始編寫自己的強大腳本來解決上述問題以及更多問題所需的所有信息。

無論您是完全新手還是有經驗的程序員，《Beginning Perl, Third Edition》都是學習Perl的理想指南。

您將學到什麼：
- 如何使用Perl的強大功能
- 如何處理Perl數據結構
- 如何構建與底層數據庫無關的數據庫應用程序
- 如何解析複雜數據
- 如何編寫工業級的面向對象Perl代碼
- 如何開始使用Perl進行Web編程
