Bob,
call_user_func is not call_user_func_array

Not in any way. call_user_func accepts any expression for the function to
call.
$func() only accepts callables.
Example:
call_user_func(getCallback());
getCallback()(); // <-- syntax error.
You *could* solve it with variable foo:
${'_'.!$_=getCallback()}();
But I'd stick to call_user_func()...
