Actually you would be better off with:

function setPart($part = NULL, $val = NULL, $append = FALSE) {
   if (isset($part) && isset($val) && @isset($this->{'_'.$part})) {
     if ($append) {
       $this->{'_'.$part} .= $val;
     } else {
       $this->{'_'.$part} = $val;
     }
     return TRUE;
   }
   return FALSE;
}

There is no need to go through the added overhead of calling 
get_class_vars and get_class, unless you want to disallow setting any 
vars not defined in the class definition.

Using the @isset(..) method you could define an addPart and delPart 
function if required, which you can not do with Phil's solution.
