I have a legacy PHP/MySQL app that calls mysql_connect(). Tons of existing downstream code makes mysql_query()
calls, either directly or through wrappers, using this connection.
For new code that I develop on the app, I would like to start using PDO.
If I make a PDO connection using the same host/user/pass/dbname credentials, might I be so lucky that under the hood, PHP will re-use the original connection? Or will PHP create two distinct connections to the server (undesirable, albeit totally understandable)?
Thanks!
