If I were you I would avoid remote database access at all costs for two reasons: - Security: opening a door for remote database access via the Internet is asking for trouble. Anybody with knowledge could compromise your database server in serious ways. - Performance: exhcanging remote database request data via the Internet is not very fast, not to mention the chances of having the connection go down due to temporary routing failures. Your data exchange should be reduced to a minimum and should be done over a reliable medium. What I suggest that you do is to use some HTTP based RPC (Remote Procedure Call) method to request just the remote data or execute the operations you need. One of most promissing solutions is to use SOAP protocol over HTTP. SOAP is a protocol for making RPC using XML formatted messages. You may want to try this PHP class that is a base for developing arbitrary SOAP servers in PHP without much knowledge of SOAP. http://phpclasses.UpperDesign.com/browse.html/package/251 Here you may find an real example one of a SOAP server via HTTP. It is used to make remote requests to a mailing list manager (ezmlm in this case), such as like subscribing and subscribing users, verifying if a user is already subscribed and return a count of how many subscribers there are in a given mailing list. http://phpclasses.UpperDesign.com/browse.html/package/177 Manuel Lemos
