Comprehensive review and examples, Juil 6 2004
Serving up dynamic content with scripting applications is all the rage now in the website development world. These scripting applications can provide customized information pages, shopping carts and content-management systems, and user-influenced web experiences. While "old-fashioned" static sites and pages still have their place, dynamic content sites are becoming more and more prevalent, primarily due to their obvious advantages, but also to their modest costs. The reason for these low costs is because the software applications are generally free, thanks to the open-source movement. Apache is an open-source web server application widely used. The most prevalent and preferred scripting application is PHP; MySQL is the predominant database management program. These three drive the great increase in dynamic content web development. While essentially free, their installation, configuration, and use requires some technical and programming skills and knowledge, but small and medium-size database-driven web sites can be managed by those not expert in programming or database management. While there is a lot of material available on the Internet about this software and database-driven sites, and a number of books available on these topics, none is as thorough and complete as "Web Database Applications with PHP and MySQL", by Hugh E. Williams and David Lane. This volume is in its 2nd edition and is a 2004 publication of O'Reilly Media Inc. The book presents an overview of dynamic web sites using open-source software and relates the principles behind generating dynamic content with database applications. The focus is on PHP, the scripting language, and MySQL, the database management software. As befits a couple of university-associated authors, the book reads much like a college textbook. The twenty chapters include an introduction to PHP, SQL (Structured Query Language), and my SQL, covering PHP v.5, the very latest version and MySQL 4.1. The PHP chapters describe the components of the language and its syntax, variables, conditions, loops, arrays, functions, types, and more. The SQL and mySQL chapters cover database basics, tables, queries, and functions. All this material is presented systemically and thoroughly. The thrust of the earlier chapters is to prepare for the comprehensive web example of "Hugh and Dave's Online Wines" site. That site is constructed from the component materials covered individually in the prior chapters - how to manage customers, creating a shopping cart, dealing with orders and shipping, searching the inventory, and authentication of buyers. There is a lot to developing a medium-sized site like this, but everything one needs to know is described and explained as the book progresses. Extra materials are included as well, including information on PEAR, which is the repository of PHP extensions - script additions which are additional functionings to PHP, or are pre-made containers of code to be used modularly with your existing code; an introduction to object-oriented programming in PHP 5; a chapter on error handling and reporting , including customized reporting; a chapter on the mixed usage of Javascript and PHP; and an important chapter on security of scripts and databases. All this includes access to the code snips at a website maintained at O'Reilly for downloading. For intermediate level developers, this is a worthwhile resource.
