23. SOAP SOAP is a simple XML-based protocol to let applications exchange information over HTTP. Or more simply: SOAP is a protocol for accessing a Web Service

24. SOAP An Envelope element that identifies the XML document as a SOAP message A Header element that contains header information A Body element that contains call and response information A Fault element containing errors and status information

25. SOAP

26. SOAP Example Plus-2.php 1.<?php 2. $client = new SoapClient("plus-local.wsdl",array( 3. "trace" => 1, "exceptions" => 0)); 4. print "plus result = ". $client- >plus(10,20 ). " "; 5. print "Request : ".htmlspecialchars ($client- >__getLastRequest() )." "; 6. print "Response: ".htmlspecialchars ($client- >__getLastResponse() )." "; 7.?>

27. SOAP Example Plus-2.php cont.-2 Request : 10 20 Response: 30

28. Configure you machine to support Web Services In php.ini Uncomment + reboot PC extension=php_soap.dll extension=php_xmlrpc.dll

29. Minimize WSDL caching time Php.ini

30. Localhost problem

31. Change localhost=>127.0.0.1 Localhost => 127.0.0.1 127.0.0.1 is a loop-back IP address for your machine.

32. Unable to connect to server solved
