Opis

Web programming is about more than creating and formatting webpages and websites, though that is often a starting point for many. Using scripting languages such as JavaScript, Perl and PH, it becomes possible to add a lot more functionality to a site. This book teaches the essentials of working with the most important web technologies. From client development using HTML and Javascript, through to full server side applications written in ASP and Perl, the complete web system is shown. Concentrating on immediately useful code rather than theory, this is a how-to book for practical and project based courses. The broad scope covered by this book begins by creating reasonably simple webpages with HTML, then working through related document and content tagging systems such as dynamic HTML and eventually XML.

O autorze

Chris Bates has been teaching a web programming course for several years to a large and diverse group of students during which he has created and refined the examples and exercises used in the book.

Blurb

This book is about implementing websites on servers and on browsers. Rather than concentrate in fine detail upon specific technologies, Chris Bates has provided a comprehensive and accessible introduction to the essentials of web development, covering an ever–expanding field in a single volume. Focusing on immediately useful code rather than theory, this is a how–to book for programmers who need quick answers.

Starting with client–side development using HTML and CSS, and moving on to more complex server–side applications written in open source languages such as Perl and PHP, the new edition of this successful textbook has been substantially revised and updated to include increased coverage of PHP and new sections on database design and configuration, Apache and MySQL. Based on years of successful teaching and taking an insightful, example–led approach, Web Programming is the complete all–in–one introduction to website programming and development, ideal for classroom use or self–study.
