• How can I set a default sort for tables in PHPMyAdmin (i.e. always "Primary key - Descending")

  - by jeremyclarke

  Even though its obnoxious in a lot of ways I use PHPMyAdmin all the time to debug database issues while writing PHP. By default it sorts tables by primary key ascending. 99% of the time I would rather have the newest data (my test data) shown at the top by default rather than the useless first few records ever saved. Is there a way to configure PHPMyAdmin to show the newest records by default? To alter similar behavior?

• a good resource or book for architecting object-oriented software

  - by Ygam

  I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

• mysql_connect VS mysql_pconnect

  - by rogeriopvl

  I have this doubt, I've searched the web and the answers seem to be diversified. Is it better to use mysql_pconnect over mysql_connect when connecting to a database via PHP? I read that pconnect scales much better, but on the other hand, being a persistent connection... having 10 000 connections at the same time, all persistent, doesn't seem scalable to me. Thanks in advance.
