Develop webservice in PHP
The document discusses how to develop a simple web service in PHP using the nusoap library in just 5 minutes; it covers the basics of SOAP and implementing a web service that returns city names based on pincodes, handling errors through SOAP faults. The presentation also addresses considerations for SOAP transactions, authentication, and provides additional resources for learning more about SOAP and web services.
