iControl + PhP ... Big IP LTM: Viprion

I am using bigip Viprion devices

• Yes bigip is reachable as I can connect to web based config utility
• iControl allowed, how to make sure ? I have downloaded icontrol SDK and put the web server (WAMP)
• Yes, I have changed appropriate IP, U/S name , PWD
• Ofcourse, I have taken whole code block

This error seems, some problem with SOAP requirements - I have uncommented the php_SOAP in php.init

I suspect on version of iControl SDK and SOAP that I have put in the server, Could you please provide the appropriete correct links to download.
