We are investigating options to build a SOAP webservice in PHP. We have some requirements:
Authentication via SOAP Headers
HTTPS
Fine control over XML used in SOAP response
Good documentation and support community.
(Optional) WS Security support
There's the following tools providing such functionality:
Native PHP SoapServer
Zend_Soap
NuSoap
WSO2 WSF/PHP
PEAR::SOAP
Zend_Soap is actually a framework-compatible wrapper for the native PHP Soap-implementation. We have some simple tests running, but SOAP headers are not supported, and we don't have full control over the XML response. For instance, the response XML has a namespace on the root element, but not on it's child elements. Pretty annoying.NuSoap is not really maintained anymore and I have read it has some issues with PHP 5.3 naming conventions.WSO2 WSF/PHP uses a php extension which has to be compiled manually. There are some dependencies and the entire compile process is not clearly documented. The documentation is scattered around the website (sometimes outdated) and in the packaged downloads. A linux binary is mentioned, but nowhere provided for download (at least not in the last 5/6 releases).I don't really know a lot about PEAR::SOAP, but I have some experience with PEAR classes. Usually they are not well-documented and do not catch errors gracefully, leaving you googling every error message, with varying outcomes.Do you know of any other tools that can help me build a full-fledged SOAP server in PHP, considering our requirements?
