 New Comment:

The classes in mysqli either need to be final or they need to be made
extendable.

some of the internal classas cannot be extended and unfortunatley they
are not marked as 'final' right now. For you that means you need to
extend it by a proxy class that reimplements the original class
protocol and uses the original class as a property.

Description:
------------
Extending the built-in class 'mysqli' doesn't give the expected and
desired result. The extended class doesn't have the members the parent
class has and is unusable.

We found a related mailinglist entry from more than a year ago:
http://www.zend.com/lists/engine2/200302/msg00244.html

The possibility to extend built-in classes is a major feature in PHP5 -
at least for us ;).

The reproduce code below is a minimal testcase - other more complicated
tests failed as well.

Reproduce code:
---------------
class DB extends mysqli
{       
}

$DB1 = new DB('localhost', 'root', '', 'probase2');
$DB2 = new mysqli('localhost', 'root', '', 'probase2');

var_dump($DB1->thread_id);
var_dump($DB1->error);
var_dump($DB1->errno);

var_dump($DB2->thread_id);
var_dump($DB2->error);
var_dump($DB2->errno);

Expected result:
----------------
int(97)
string(0) ""
int(0)
int(98)
string(0) ""
int(0)

Actual result:
--------------
<br />
<b>Notice</b>:  Undefined property:  DB::$thread_id in
<b>d:\htdocs_php5\ProBase2\TRUNK\probase\libsys\test.php</b> on line
<b>10</b><br />
NULL
<br />
<b>Notice</b>:  Undefined property:  DB::$error in
<b>d:\htdocs_php5\ProBase2\TRUNK\probase\libsys\test.php</b> on line
<b>11</b><br />
NULL
<br />
<b>Notice</b>:  Undefined property:  DB::$errno in
<b>d:\htdocs_php5\ProBase2\TRUNK\probase\libsys\test.php</b> on line
<b>12</b><br />
NULL
int(97)
string(0) ""
int(0)
