Currently, I haven't figured out a way to use it with php. MySQL is doable with remoting, but you need either a java server or coldfusion to get it going. Coldfusion is the only one I've messed with. It's super easy to get connected to your database via remoting. Basically, you write some server-side script (main.asc) to make a remoting connection to a remoting server, and then return the data to a shared-object. Then the updates to that SO are sent to each subscribed client. There aren't many examples online yet, but hopefully there will be soon. Hope that helps at least get you looking in the right places!
