Reindl's (funny) comments aside. Why still use phpMyAdmin in this day and age. Nearly every maria/percona/mysql client supports ssh tunneling. SequelPro on Mac, Heidi (or others) on Windows, and any windows client running through wine if your desktop/laptop is linux. Also developers can just use intellij or similar IDE's that have a database pane.
Trusting administration to an exposed phpMyAdmin in this day and age frightens me greatly. Also if you had an HIDS server running to track bad phpMyAdmin logins i bet there would be a ton of alerts. I've blocked all such attempts in my IPS even though i don't have phpMyAdmin.
I realize this does not answer your question, but if this fits into your architecture i'd say good by to that web interface.
