[wp-testers] update_option() not always working in WP 3.0 beta 2

[Dion Hulse (dd32)]

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.
