ASP to PHP (Secure MS Access connection)..

I'm trying to convert an ASP site to PHP, and my problem is this: I've set up the the DSN on my machine to utilize the built-in odbc functions as I would any Access DB. Because this is a "secure" db, i'm supposed to reference the MDW file as opposed to the MDB... Well I can't seem to get it to work. Here is the connection string thats used in ASP: Application("WCSChamber_ConnectionString") = "DSN=WCSChamber;DBQ=D:\Clients\WCS\wcsdat.mdb;DriverId=281;FIL=MS Access;MaxBufferSize=2048;PageTimeout=5;SystemDB=D:\Clients\WCS\wcs.MDW;" Does anyone have any idea how i can connect to this with PHP? Any tips would be appreciated.. thanks.
