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

Exposing a PHP/Oracle Application as a Web Service Using PHP SOAP Extension


PHP's SOAP extension is an implementation of the SOAP protocol for PHP. Written in C, it provides a performance advantage over the PEAR::SOAP implementation, which is written in PHP.

In the following sections, you will learn how to expose a PHP/Oracle application as a web service with the help of PHP's SOAP extension.

Communicating Using SOAP

As mentioned, SOAP is a messaging protocol. What this means is that SOAP clients and SOAP servers interact by sending SOAP messages to each other.

Note

A SOAP message is a SOAP-formatted XML document used to transport information between SOAP-based interfaces. For more information on SOAP, you can refer to the W3C SOAP Recommendation documents. Links to the latest versions of these documents can be found at http://www.w3.org/TR/soap/.

The following figure illustrates the general structure of a SOAP message.

As you can see in the figure, an XML document representing a SOAP message...
