Overview of this book

Oracle Database gets high marks for performance, reliability, and scalability. Building and deploying your PHP applications on Oracle Database enables you to combine the power and robustness of Oracle and the ease of use, short development time, and high performance of PHP. When used in a complementary way, PHP and Oracle allow you to build high-performance, scalable, and reliable data-driven Web applications with a minimum of effort.When building a PHP/Oracle application, you have two general options. The first is to use an Oracle database just to store data, performing all the operations on that data on the client side; the other is to use the database not only to store data, but also to process it, thus moving data processing to the data. While building the key business logic of a database-driven PHP application inside the database is always a good idea, you should bear in mind that not all of the databases available today allow you to do. The Oracle database, which offers record-breaking performance, scalability, and reliability, does. The partnership of Oracle and the open-source scripting language PHP is an excellent solution for building high-performance, scalable, and reliable data-driven web applications.This 100% practical book is crammed full of easy-to-follow examples. It provides all the tools a PHP/Oracle developer needs to take advantage of the winning combination. It addresses the needs of a wide spectrum of PHP/Oracle developers, placing the emphasis on the most up-to-date topics, such as new PHP and Oracle Database features, stored procedure programming, handling transactions, security, caching, web services, and Ajax.

Preface

Implementing Master/Detail Solutions with AJAX


The sample application discussed in the preceding sections is a basic example, of course. Nevertheless, it shows you how to use the XMLHttpRequest JavaScript class to make asynchronous calls to PHP/Oracle scripts.

In the following sections, you will build a more complex sample application showing how to make a PHP/Oracle application more responsive and dynamic with the help of AJAX.

Planning a Master/Detail Solution that uses AJAX

In the preceding sample, you use AJAX to automatically update a page displaying some rapidly changing data stored in the database, actually updating a few numbers on the page. Of course, you might use AJAX to solve more complicated tasks. For example, you might implement an AJAX-based solution that makes the database generate blocks of well‑formed HTML code and then dynamically insert those blocks in the browser's HTML tree, significantly updating the loaded page without actually performing a full reload. Fortunately...
