well gee thanks for explaining on how you figured it out...
problem is you dont have the soap etention with your php.
Look up the following inside your script file
If you can't find Soap Client set to enabled
Do the following:
Locate php.ini in your apache bin folder, I.e Apache/bin/php.ini
Remove the ; from the beginning of extension=php_soap.dll
Restart your Apache server
Look up your phpinfo(); again and check if you see a similar picture to the one above
If you do, problem solved!
