About this tutorial

This tutorial shows how to build Web services in PHP using the PHP Development Tools (PDT) plug-in. The PDT project was released in its 1.0 release version in September 2007 and was followed by a V1.0.2 release in January 2008. The PDT project gives you first-class abilities to edit, debug, and deploy PHP applications in the Eclipse IDE.

Objectives

This tutorial has three main objectives. The first is to become familiar with the PDT project and learn how to create and deploy useful PHP projects. The second is to learn about the philosophy behind contract-first development. Third, this tutorial serves as an informative overview of the basic parts that make up a Web Services Description Language (WSDL) file.

Prerequisites

You should have experience with PHP development.

System requirements

To get the most out of this tutorial, you need to install Eclipse and the PDT plug-in. You must also install the Eclipse Web Standard Tools (WST) subproject.

Note: If you installed the Java™ 2 Platform, Enterprise Edition (J2EE) bundle of Eclipse, you already have WST.

To follow the examples, you need Eclipse and one of the operating systems that Eclipse supports — Mac OS X, Microsoft® Windows®, or Linux®. You also need a Java Runtime Environment (JRE) — at least JRE for Java 5 is recommended.
