Christian Weiske has posted a review of the Packt Publishing book "Mastering phpMyAdmin 3.1" that was offered by the publisher.
"Mastering phpMyAdmin 3.1 for Effective MySQL Management" is a book about - phpMyAdmin. phpMyAdmin is a tool that most web developers use on a daily basis and know in and out. The existing knowledge about PMA is the hurdle that will make most devs refrain from buying the book; 75% of the information presented in the book was already in my head, having used PMA for over half a dozen years now.
He mentions a few things (like the multi-table query generator and split-file exports) that he didn't know the tool even had. He recommends the book overall, though and notes that he learned quite a bit about the tool despite having worked with it for years already.
You can find more information on the book on the Packt website.
