Bug Type: Documentation problem
PHP Version: Irrelevant
New Comment:
There is in fact something special with typehinted arguments, as only
few types of values are permitted:
function foo(Bar $b = 2) {} is not permitted, for example

Every parameter can have a default value. There's nothing special with
type-hinted parameters.

Description:
------------
The documentation is missing the fact that the following statement is
possible :
function o1(Foo $arg0 = null, $x) {}
function o2(Foo& $arg0 = null, $x) {}
The code above works on 5.2.3 (which is fine).
The fact that a typehinted parameter can have a default (enforced to
null) value should be explained at least in the type hinting part of the
doc [http://ch2.php.net/manual/en/language.oop5.typehinting], with the
version of php that support it (I can't remember it it was working on
5.1).
Note also that the syntax can be misleading: one can easily think that
$arg0 take a default value, and that o1('a') is possible (or
o1(,'a')?).
