PHP version: 5.2.4RC1
PHP Bug Type: Class/Object related
Bug description: PHP4 backwards-compatibility slightly broken
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)
