I'm pretty sure you have to add () on the end of those function names to get PHP to actually *call* the function, so you need: $helpme->SET(); $helpme->RETREIVE(); Without the parentheses, PHP evaluates the name of the function (returning its "handle"), but then doesn't know what to do with it so just throws it away on seeing the terminating semicolon. As far as PHP is concerned, you could quite legitimately want to do something entirely different with the handle, such as assigning it to a variable -- PHP won't assume you want to call it as a function just because it happens to be a function name. For instance, the following should work (I think! - although I haven't tested it): $method = $helpme->SET; $method(); In fact, you can ask PHP to try and call anything as a function by appending parentheses, so this should work too: $method = "SET"; $helpme->$method(); Cheers!
