The constructor of the object initializes the id variable to be null
(which is needed in other cases).

Description:
------------
I'm using the mysql_fetch_object's ability to create a custom object.
The constructor of the object initializes the .
The scripts simply gets all the data from the a table and uses
mysql_fetch_object to create the objects. The id property however is not
set, it is null.
I think that the mysql_fetch_object function first creates an object
setting properties and than it turns this object into an object of the
specified type, calling the constructor in the proces.

looking at the php source for mysql_fetch_object shows me that a hash
is retrieved first: php_mysql_fetch_hash
After that the hash is converted into an object:
object_and_properties_init

I think an object should be created calling its constructor and than
after that is done, the properties should be set.

Reproduce code:
---------------
<?php
/*
   USE test;
   DROP TABLE IF EXISTS `tbl_content`;
   CREATE TABLE `tbl_content` (
   `id` int(11) NOT NULL auto_increment,
   `content` text,
   PRIMARY KEY  (`id`)
   ) ENGINE=MyISAM DEFAULT CHARSET=latin1;
   INSERT INTO `tbl_content` VALUES
(1,'asdf1'),(2,'asdf2'),(3,'asdf3');
 */
$link = mysql_connect('localhost', 'test', 'test');
mysql_select_db('test');
class tbl_content {
  var $id;
  var $content;
  function tbl_content() {
    $this->id = null;
  }
}
$result = mysql_query("SELECT * FROM tbl_content", $link);
if (!$result) {
  die(mysql_error());
}
while ($obj = mysql_fetch_object($result, 'tbl_content')) {
  var_dump($obj);
}
?>


Expected result:
----------------
object(tbl_content)#1 (2) {
  ["id"]=>
  string(1) "1"
  ["content"]=>
  string(5) "asdf1"
}
object(tbl_content)#2 (2) {
  ["id"]=>
  string(1) "2"
  ["content"]=>
  string(5) "asdf2"
}
object(tbl_content)#1 (2) {
  ["id"]=>
  string(1) "3"
  ["content"]=>
  string(5) "asdf3"
}


Actual result:
--------------
object(tbl_content)#1 (2) {
  ["id"]=>
  NULL
  ["content"]=>
  string(5) "asdf1"
}
object(tbl_content)#2 (2) {
  ["id"]=>
  NULL
  ["content"]=>
  string(5) "asdf2"
}
object(tbl_content)#1 (2) {
  ["id"]=>
  NULL
  ["content"]=>
  string(5) "asdf3"
}
