Is it possible to run a php soap api operation in a web browser

In a开发者_高级运维xis2 on Java it's possible to run operations in the browser by the way you send the url

for example

localhost:8080/axis2/services/SimpleService?wsdl

could have operations implemented by writing urls like so

localhost:8080/axis2/services/SimpleService/hello?param0=xxx

My Question is can you do the same in PHP5 SoapServer where the url is as below?

localhost/soaptest/index.php?wsdl

I would use the poster extension for Firefox for this.
