The APIlity PHP Library provides an object-oriented way to easily access and manage the Google AdWords API from within PHP. This comes along with an abstraction from the SOAP and WSDL details.
PROJECT MOVED to https://github.com/f00b4r/nusoap
NuSOAP is a rewrite of SOAPx4, provided by NuSphere and Dietrich Ayala. It is a set of PHP classes - no PHP extensions required - that allow developers to create and consume web services based on SOAP 1.1, WSDL 1.1 and HTTP 1.0/1.1.
This project is a PHP-based SOAP server which provides mainly MySQL data to a SOAP client. It exposes all available DB objects (views and tables) to any SOAP client based on NuSOAP's SOAP server.
PHP2WSDL is a WSDL generator for PHP Web Service support, namely the built-in SOAP API. The definition (WSDL) are derived from the PHP object class, its method functions, the input arguments, output parameter, etc.
JSoapTest provides a simple web interface for testing SOAP Servers. It parses the WSDL, builds a form for entering the SOAP Request parameters, calls the SOAP Server, and displays the result.
SOAP-SQL generates a web service WSDL based on user-defined SQL statements with only a few lines of code. It relies on NuSOAP and PEAR MDB2 (DB abstraction layer), so it works with most any database. No PHP extensions required.
phpXMLP aims to be a XML Protocol implementation for PHP. It should provide support for SOAP 1.2 and WSDL 1.0. It follows very closely the design proposed by the XML Protocol Abstract Model Working Draft published on the 9th of July, 2001 by the W3C.
