Now gettype is totally inconsistent:

Now
-------
$b = array();
 
function b() { ; }
 
print gettype($b);
-------

retruns "array" which is perfectly correct.

But
-------
class A { 
 var $a = array();
 function a() { ; }
}
 
$o = new A;
print gettype($o->a);
-------

returns "user function" which is not only false, but also
inconsistent to what gettype() returns in the upper case.
