PHP Bug Type: Documentation problem
Bug description: Typehinting support null value but the docs hide the facts!
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')?).
