Given the nature of your project forget MysQL and phpAdmin. At most you may use sqlite. Sqlite data is stored in one file, locally, you can move it back it up easily. Sqlite doesn't need any server.
If you don't see How sqlite would benefit your mud, that would be strange, but then drop it and use pickled dictionaries if you're familiar with them.

Actually you mentioned a "player database" in your original post. Player with their stats are typically something that may ends up in a database, along with any object and its properties.
That's why people suggested to use a database. Databases provide then powerful tools to fetch, search and edit your data. Performances on disk access would be handled by sqlite itself, something you may care by yourself if you use dictionaries.

Or maybe your mud doesn't store anything on disk, every run start fresh, in that case just use dictionaries.
