Interesting ;) the documentation should also mention that the old PHP4
beahviuor is clearly the wrong thing.

Nuts, typo. Both the `Users` should start:
class Users extends users_base {

Oh, thought I'd add a workaround:
class Users {
function Users() {
parent::Users();
}
}
Unfortunately for me, there are one hell of a lot of classes that our
previous programmer built in this fashion, making the workaround
impractical.

Description:
------------
PHP4-style constructors do not function, in PHP5, in the same way as
they do in PHP4.
The issue lies in when parent constructors are called, or not as the
case may be.
Reproduce code:
---------------
class users_base {
function Users() {
echo "users_base::Users()\n";
}
}
class Users {
// Nothing here.
}
$base = new users_base();
$child = new Users();
Expected result:
----------------
Running the sample code in PHP4 will give the expected result:
users_base::Users()
users_base::Users()
Whereas PHP5 will not call the Users() function in the parent class:
users_base::Users()
I class this as a bug because of the expected PHP5 behaviour as well as
the evident PHP4 behaviour. If the users_base function is renamed to
__construct(), it will get called on BOTH instantiations, as PHP4 does
with its style.
Actual result:
--------------
users_base::Users()
(The child class does not call Users() on instantiation)
