ok, smiling one. ;^)
usually, one db error will cascade multiple errors in php since most db
functions rely on a resource provided by another db function. anyway...what
you've got is a failure to connect and yet you continue to try to use other
functions that rely on that connection which in turn throws errors number 2
and 3.
your literal problem is that access (shitty as it is) stores its data in a
file. when php tries to open that db/file, your pc tries to access it as
IUSR_<computer name here>...that is, if you're using IIS (incredibly
insecure server). you must allow read/write permissions for that user on the
directory in which your mdb resides.
btw, you do *NOT* need a dsn to connect to the db, as a standard odbc
connection string in the form of:
"Driver={Microsoft Access Driver
(*.mdb)};Dbq=C:\mydatabase.mdb;Uid=Admin;Pwd=;"
will work just fine.
(look at http://www.connectionstrings.com/ for most common connection
strings)
does that explain things to your satisfaction?
