SOAP and WSDL

PHP-SOAP

Simple SOAP

• Using SOAP without WSDL

• Hard to do, requires good knowledge of SOAP library
• WSDL parsing is still being developed, hand coding can be more interoperable

• SOAP libraries that use WSDL

• Very easy to use, but most SOAP libraries do not handle WSDL well enough yet
• Slow, library must parse WSDL on every instance

• Generating Proxies for robust Web Services

• Tools can take their time analyzing WSDL to generate robust proxy classes that increase interoperability.
