Now i understood how SOAP works, its very good example

Thank you very much so simple example. This is more than many words.

Helped me to. Thanks.

I am getting an an exception error on login as "Not Found"

The var_dump gave me the below info

object(SoapFault)#2 (9) { ["message":protected]=> string(9) "Not Found" ["string":"Exception":private]=> string(0) "" ["code":protected]=> int(0) ["file":protected]=> string(41) "C:\xampp\htdocs\soap-test\soap-client.php" ["line":protected]=> int(5) ["trace":"Exception":private]=> array(2) { [0]=> array(4) { ["function"]=> string(11) "__doRequest" ["class"]=> string(10) "SoapClient" ["type"]=> string(2) "->" ["args"]=> array(5) { [0]=> string(548) " test_usertest_password " [1]=> string(46) "http://localhost/api/wsdl/orgs/soap-server.php" [2]=> string(15) "urn:LoginAction" [3]=> int(1) [4]=> int(0) } } [1]=> array(6) { ["file"]=> string(41) "C:\xampp\htdocs\soap-test\soap-client.php" ["line"]=> int(5) ["function"]=> string(6) "__call" ["class"]=> string(10) "SoapClient" ["type"]=> string(2) "->" ["args"]=> array(2) { [0]=> string(5) "login" [1]=> array(2) { [0]=> string(9) "test_user" [1]=> string(13) "test_password" } } } } ["previous":"Exception":private]=> NULL ["faultstring"]=> string(9) "Not Found" ["faultcode"]=> string(4) "HTTP" }

Simple and best example for understand how a SOAP server works with wsdl. Thanks Umid.

any idea why i would be getting this error? "looks like we got no XML document"
what should the generated response look like?
