I'm pleased to announce that the May '08 CTP for the SQL Server 2005 Driver for PHP is now available for download here. Keep in mind that this is a technology preview and is not intended for production purposes. The documentation for the driver is available on our MSDN site. We look forward to your feedback on the new MSDN forum specifically for the driver.
Please stay tuned, as we will soon be blogging about some of the new functionality in the May '08 CTP.
