Preparing to use SOAP?

[chiprivers]

I have an apache server set up with PHP and MySQL but I am currently trying to get my head around XML and SOAP and would like to set up my server to work with this. 

 

I am sure on one of the earlier tutorials I found told me how to set up / enable SOAP and I think it involved downloading something but I can not find that tutorial again.  Can anybody help me with some step by step instructions on how to prepare my server to use SOAP?

 

If it helps or makes any difference to the procedure, I am hoping to be able to integrate the services offered by BetFair API http://bdp.betfair.com/freeapi.php#01.  Maybe somebody has worked with BetFair before!?

I think I have got step one!

 

I have downloaded NuSoap from http://sourceforge.net/project/showfiles.php?group_id=57663.  I have extracted the downloaded files and placed the folder in my root directory so that I can call the nusoap.php file from my php scripts.

 

Not sure if there is anything else to do to enable the use of SOAP within my scripts, trying to get my head around its use so that I can test it out!

I think I have all the jigsaw pieces but I just dont know how to put them together, does anybody have the picture on the box!!??

 

I have NuSOAP on my php server and I have gained a basic understanding of how soap works by creating an 'envelope' XML request and sends it to the soap server, this sending back an XML response.  The thing I can get my head around is how I use the NuSOAP and PHP to send this request!

 

I have found a couple of tutorials that offer direction but none of them seem to make use of the WSDL that is available from the web service that I am using, and supposedly simplifies the procedure.
