We needed to be able to set the application name in a mssql connection string, but php doesn't current toy support it. This can be very helpful while debugging/profiling php-mssql from the SQL server side of things. Without this patch all mssql connections have a hard coded application name of 'PHP 5'. https://bugs.php.net/bug.php?id=60124 Please let me know if you have any problems applying the patch or comments on how we can make it better/get it added to the main codebase. Thanks, -Dan
