Scripting PHP Web services with PEAR

PHP has various ways in which you can implement Web services, including NuSOAP, PHP-SOAP, and PEAR (PHP Extension and Application Repository). Some of these packages are more mature than others, but in essence they achieve the same goal, which is to deploy Web services in PHP. We will use PEAR, which is is not a standalone package for Web services but more of a framework for building PHP applications, and which includes a Web services module.
