Sounds like you've run into either:
a. a Bug with PHP
b. a Bug in a Caching layer you've got enabled
This exact code works for me:
$option_name = 'test';
$value = (object) array('test' => true);
$value->var1 = 1;
update_option ($option_name, $value);
$value->var2 = 2;
update_option ($option_name, $value);
$value->var3 = 3;
update_option ($option_name, $value);
var_dump(get_option($option_name));
delete_option($option_name);
Resulting in:
object(stdClass)#278 (4) { ["test"]=> bool(true) ["var1"]=> int(1)
["var2"]=> int(2) ["var3"]=> int(3) }
Thats running the latest SVN edition, and PHP 5.3.1
Checking http://www.php.net/manual/en/language.oop5.object-comparison.php
confirms that the existing code should work as expected.

Hi all,
In a plugin I store an object in an option, and the typical flow is as
follows:
$value = get_option ($option_name);
$value->var1 = $new_var1;
update_option ($option_name, $value);
$value->var2 = $new_var2;
update_option ($option_name, $value);
$value->var3 = $new_var3;
update_option ($option_name, $value);
and so on. That used to work fine with WP 2.9.2, both with PHP4 and PHP5.
With WP 3.0 beta 2 and PHP4, no problem.
With WP 3.0 beta 2 and PHP5, apparently only the first update_option()
call is
honored, and following calls are not honored because update_option()
finds that
$newvalue === $oldvalue (lines 503-504 in wp-includes/functions.php)
and does not update the database. If I remove those two lines, the
plugin works
again. If in my code I replace
update_option ($option_name, $value);
with
update_option ($option_name, 0);
update_option ($option_name, $value);
the plugin works as well.
According to a user report I received, the problem was first noted in
WordPress 3.0 alpha (svn13807 – 2010.03.23 @ 20.03).
Is this issue already known? Or am I missing something? If interested,
the
plugin that stopped working in WP 3.0 is Menubar 4.7.
Thank you all
Andrea
