php update error

Hi,

I just updated php 5.3.3 to 5.3.28 in the interworx -> software updates.
My problem is the php is still remained on version 5.3.3, even if i tried to reinstall package with "yum reinstall php-iworx". The reinstall finished sucessfully but the php is still on 5.3.3.
Is anybody have an idea how can i fix this?

Thanks, Gabor.
