 New Comment:

expected behavior, b inherits a's constuctor and a::__construct
obviously does not exist

Description:
------------
In php's OOP implementation, the "class-name method" fallback used when
a __construct() method fails seems to have strange effects. Non-existant
methods seems to be callable. It only happens if no constructor is
defined in class b.

This can be reproduced in php4.4, 5.1, 5.2-cvs, 6-cvs :



Reproduce code:
---------------
class a { function a($arg='') { echo $arg; } } 
class b extends a {} 

$b = new b; 
$b->b('foo');
$b->__construct('foo');

Expected result:
----------------
Fatal error: Call to undefined method b::b() in ...
Fatal error: Call to undefined method b::__construct() in ...

Actual result:
--------------
foo
Fatal error: Call to undefined method b::__construct()
