Create DSN in PHP

[ow-phil]

After searching and searching I have not been able to figure this out. I need to create a DSN for PHP to be able to access the MS-Access Database via ODBC. I have got ODBC working, only now I need a DSN. How do I put a DSN in PHP. I have got a DSN for Chillisoft ASP, but that doesnt help any.

The dsn name I want is "testing" - username and password are blank and the DB Name is "testing.mdb". I am using UnixODBC on a Cobolt RAQ4 Server with PHP 4.1.2 and MySQL 3.23.54.

Thanks in advance,

Phil
