On NewsForge, an article with a look at phpMyAdmin has been posted, a "getting started" guide for those not familiar with the software.
So many open source projects depend on MySQL that it's almost impossible for administrators and other open source enthusiasts to avoid working with at least one MySQL database. MySQL's command line interface is easy enough to use, but if you don't feel like reaching for a five-pound MySQL reference book or Googling for proper SQL syntax, phpMyAdmin is a great alternative to learning MySQL commands by heart.
They take a brief look at how it's set up, though it's not an installation tutorial, more about configuration. They guide you through some of the interface before getting to the real functionality - inserts, selects, dumping/restoring data, working with users, and checking/repairing tables when things go awry.
