Problems in a function - Probably an easy answer!

I am using this example to start up a SOAP server and run a few functions. http://www.phppatterns.com/index.php/article/articleview/41/1/2/ It seems like when I do my own little function inside the Test1 class, like 'function serverTimestamp() or function hello()' in the example, it won't do any advanced operations. I can do simple math, like a+b, and spit out a value, but as soon as I do a SQL query or anything like that, it returns the SOAP fault object, with a timed out read. Can anyone help me? ....Dustin
