Silly question; I've been wanting to use Doctrine with CodeIgniter on a personal portfolio site, but Doctrine indicates that it needs PHP 5.2.3 or greater. I submitted a ticket to my hosting provider asking when they would be upgrading PHP (they were running 5.2.1). I just got a message saying they've updated to 5.2.12, which is greater than 5.2.3.
Is this true? I've looked at the php.net downloads page but it's hard to tell which is more recent. I think I may be misinterpreting 5.2.12 as 184.108.40.206 - obviously 12 is higher than 3, but is that how the versions are numbered?
