What I would like to do is from URLs B, C, D, etc. conect to a MySQL database on URL A and retrieve data and have it displayed on URLs B, C, D, etc. Is this possible? If so can you please point me in the right direction.
Could you clarify this question? But, perhaps you are trying to pass information via the url?:
http://www.url.com/?a=this&b=that&c=12
You can substitue "localhost" in mySQL to "remote_mysql_server_name_or_ip:3366" (or whatever port it's running on if not standard) -- you will need to have your calling site have "remote access" granted to it though. This is simple enough if your host uses cPanel or something similar ....
