Learning Perl, popularly known as "the Llama," is the book most programmers rely on to get started with Perl. The bestselling Perl tutorial since it was first published in 1993, this new fifth edition covers recent changes to the language up to Perl 5.10. This book reflects the combined experience of its authors, who have taught Perl at Stonehenge Consulting since 1991. Years of classroom testing and experience helped shape the book's pace and scope, and this edition is packed with exercises that let you practice the concepts while you follow the text. Topics include: * Perl data & variable types * Subroutines * File operations * Regular expressions * String manipulation * Lists & sorting * Process management * Smart matching * Using third party modules Perl is the language for people who want to get work done. Originally targeted to sysadmins for heavy-duty text processing, Perl is now a full-featured programming language suitable for almost any task on almost any platform-from short fixes on the command line to web applications, bioinformatics, finance, and much more. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.

Perl is a powerful programming language that has grown in popularity since it first appeared in 1988. The first edition of this book, "Programming Perl," hit the shelves in 1990, and was quickly adopted as the undisputed bible of the language. Since then, Perl has grown with the times, and so has this book. "Programming Perl" is not just a book about Perl. It is also a unique introduction to the language and its culture, as one might expect only from its authors. Larry Wall is the inventor of Perl, and provides a unique perspective on the evolution of Perl and its future direction. Tom Christiansen was one of the first champions of the language, and lives and breathes the complexities of Perl internals as few other mortals do. Jon Orwant is the editor of "The Perl Journal," which has brought together the Perl community as a common forum for new developments in Perl. Any Perl book can show the syntax of Perl's functions, but only this one is a comprehensive guide to all the nooks and crannies of the language. Any Perl book can explain typeglobs, pseudohashes, and closures, but only this one shows how they really work. Any Perl book can say that "my" is faster than "local," but only this one explains why. Any Perl book can have a title, but only this book is affectionately known by all Perl programmers as "The Camel." This third edition of "Programming Perl" has been expanded to cover version 5.6 of this maturing language. New topics include threading, the compiler, Unicode, and other new features that have been added since the previous edition.

"Learning Perl", better known as "the Llama book", starts the programmer on the way to mastery. Written by three prominent members of the Perl community who each have several years of experience teaching Perl around the world, this latest edition has been updated to account for all the recent changes to the language up to Perl 5.8. Perl is the language for people who want to get work done. It started as a tool for UNIX system administrators who needed something powerful for small tasks. Since then, Perl has blossomed into a full-featured programming language used for web programming, database manipulation, XML processing, and system administration - on practically all platforms - while remaining the favorite tool for the small daily tasks it was designed for. You might start using Perl because you need it, but you'll continue to use it because you love it. Informed by their years of success at teaching Perl as consultants, the authors have re-engineered the Llama to better match the pace and scope appropriate for readers getting started with Perl, while retaining the detailed discussion, thorough examples, and eclectic wit for which the Llama is famous. The book includes new exercises and solutions so you can practice what you've learned while it's still fresh in your mind. Here are just some of the topics covered: data structures, minimal matching, threading, data parsing, references, objects, modules, and package implementation. If you ask Perl programmers today what book they relied on most when they were learning Perl, you'll find that an overwhelming majority will point to the Llama. With good reason. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.

DBI是Perl数据库编程的主要接口。它与数据库产品无关，且为几乎所有的数据库产品提供了一致的子例程集。DBI将实际的数据库驱动程序与API分离，这样DBI程序可以处理任何数据库，甚至可以同时处理不同厂商的多个数据库。 对新手而言，本书解释了DBI的体系结构和如何编写基于DBI的程序；对专家而言，本书阐述了DBI的技术内幕和每个DBD的特性。
