Just because we're very busy putting the finishing touches on the SQL Server 2008 documentation, doesn't mean that we stop releasing other things too! In fact, we just released the next Community Technology Preview (CTP) release of the SQL Server Driver for PHP. Documentation for this release is included in the package which you can download from the Microsoft Download Center. Or, you can also read the documentation online in the MSDN Library. To find out the latest updates and changes from the February CTP release, be sure to check out the What's New topic.
