PunBB currently supports MySQL, PostgreSQL and SQLite. If your database of choice is missing from the drop-down menu below, it means this PHP environment does not have support for that particular database. More information regarding support for particular versions of each database can be found in the FAQ.
PunBB has detected that your PHP environment supports two different ways of communicating with MySQL. The two options are called standard and improved. If you are uncertain which one to use, start by trying improved and if that fails, try standard.
