Not true, actually.  $function() is considerably faster than call_user_func() 
or call_user_func_array().  call_user_func_array(), however, lets you pass in 
an arbitrary number of parameters while the other two do not.

"If nature has made any one thing less susceptible than all others of 
exclusive property, it is the action of the thinking power called an idea, 
which an individual may exclusively possess as long as he keeps it to 
himself; but the moment it is divulged, it forces itself into the possession 
of every one, and the receiver cannot dispossess himself of it."  -- Thomas
