: uplaod a database like a a regular file and access it through a webpage (on the same server/website)?
: eg. uplaod an access file and access it with php (for example)
: or something similar??
That depends on the remote server. Is it Windows based? Then you should definitely be able to access an .mdb file using PHP's odbc_* functions.
If it's Linux based, it's a little more iffy. It's possible to access an .mdb file under Linux using ODBC as well, but ODBC support isn't standard in Linux. If you control the remote server, check out http://www.unixodbc.org/.
If not, you'll have to talk to the admin.
