PHP PDO encrypted / ssl data layer

After doing some research I heard only PHP 5.3.6+ supports PDO and SSL. I am not sure the validity of this, so I thought I would ask, and see if anyone has some suggestions for using PDO and transferring data between 2 mysql servers. It does not necess开发者_如何学Goarily have to be SSL. Any form of encryption using a manually set key could work, I am just not sure where to begin. Thanks!

You don't need PDO to have two MySQL servers talk to each other. Using replication and federated tables, you can do it directly without involving another layer. And that linkage can take place over an SSL connection as well.
