### 开始学习Ajax与PHP：从新手到专家 #### 标题解读 - **标题**：“Beginning Ajax with PHP”（开始学习Ajax与PHP）：这个标题明确了本书的主要内容是介绍如何利用PHP技术结合Ajax来开发交互式的Web应用程序。标题中的“Beginning”表明这是一本适合初学者入门的书籍。 #### 描述解析 - **描述**：“Beginning Ajax with PHP From Novice to Professional”（开始学习Ajax与PHP：从新手到专家）：这段描述进一步强调了本书的目标读者是从零基础的新手到希望成长为专业开发者的学习者。它承诺通过阅读本书，读者能够掌握利用PHP和Ajax构建强大互动网站应用的技术。 #### 知识点概述根据提供的部分信息，我们可以总结出以下核心知识点： 1. **Ajax简介** - **定义**：Ajax全称为Asynchronous JavaScript and XML（异步JavaScript与XML），是一种在无需重新加载整个网页的情况下，就能够更新部分网页的技术。 - **作用**：通过在后台与服务器进行少量数据交换，Ajax可以使网页实现异步更新。这对于改善用户体验非常有帮助，因为它可以避免用户在等待页面加载时所造成的不便。 2. **PHP与Ajax的结合** - **PHP简介**：PHP是一种广泛使用的开源脚本语言，特别适用于Web开发，并可嵌入HTML中。 - **PHP与Ajax的关系**：PHP通常用于处理服务器端的数据，而Ajax则负责客户端的交互逻辑。当用户在前端执行某些操作时，Ajax会向服务器发送请求，服务器上的PHP脚本处理这些请求并返回响应，然后Ajax将响应的数据展示给用户，而无需刷新整个页面。 3. **构建交互式Web应用** - **基础知识**：本书将从基本概念入手，详细介绍PHP和Ajax的基本原理，以及如何使用这两种技术来创建动态的、交互式的Web应用程序。 - **实战案例**：书中不仅包含理论知识，还会提供实际的操作步骤和代码示例，帮助读者理解如何在真实项目中应用这些技术。 4. **提高技能水平** - **进阶内容**：对于希望进一步提升自己能力的读者，本书还涵盖了更高级的主题，如优化性能、增强安全性等。 - **最佳实践**：书中提供了许多关于如何编写高质量、可维护的代码的最佳实践，这些都是作者多年经验的总结。 5. **版权与出版信息** - **作者**：Lee Babin - **出版社**：Apress - **版权年份**：2007年 - **ISBN**：ISBN-13 (pbk): 978-1-59059-667-8；ISBN-10 (pbk): 1-59059-667-6 6. **编辑团队介绍** - **主要编辑**：Jason Gilmore - **技术审稿人**：Quentin Zervaas - **编委会成员**：Steve Anglin、Ewan Buckingham、Gary Cornell、Jason Gilmore、Jonathan Gennick、Jonathan Hassell、James Huddleston、Chris Mills、Matthew Moodie、Dominic Shakeshaft、Jim Sumser、Keir Thomas、Matt Wade 7. **出版流程** - **项目管理**：Richard DalPorto - **校对编辑**：Damon Larson、Jennifer Whipple - **生产编辑**：Laura Esterman - **排版**：Dina Quan - **校对**：Lori Bring - **索引**：John Collin - **美术设计**：April Milne - **封面设计**：Kurt Krames 《开始学习Ajax与PHP：从新手到专家》是一本全面介绍了如何使用PHP和Ajax来开发交互式Web应用的指南书。无论你是刚刚接触Web开发的新手，还是想要进一步提升自己的技能的专业人士，这本书都能为你提供有价值的指导和支持。

Beginning Ajax with PHP: From

Novice to Professional

Dear Reader,

With the emergence of Ajax, gone are the days of clicking and waiting on the

Web. Users now have the luxury of accessing desktop-like applications from any

computer hosting a browser and an Internet connection. Likewise, developers

now have more reason than ever to migrate their applications to an environment

that has the potential for unlimited users.

Yet despite all that Ajax promises, many web developers readily admit being

intimidated by the need to learn JavaScript (a key Ajax technology). Not to

worry! I wrote this book to show PHP users how to incorporate Ajax into their

web applications without necessarily getting bogged down in confusing

JavaScript syntax. I’ve chosen to introduce the topic by way of practical examples

and real-world applications. After a rapid introduction to Ajax fundamentals,

you’ll learn how to effectively use Ajax and PHP together, followed by further

instruction regarding dynamically updating pages using data retrieved from a

MySQL database. From there, you’ll learn how to create practical Ajax-driven

features such as a dynamic file upload and thumbnail-generation tools, culmi-

nating in the creation of an Ajax-based photo gallery.

In later chapters, I focus on other timely topics, such as web services and

building spatially enabled web applications using the Google Maps API. The

book concludes with an overview of topics that will make you a more effective

Ajax developer, including a look at cross-browser issues, security, testing and

debugging, and finally, an introduction to the document object model (DOM).
