If you are a regular user of phpMyAdmin like me, then you’ll have more than once had the problem of returning to your phpMyAdmin tab after a while and being prompted to login again, because you’ve been idle for 1440 seconds (=24 minutes). This is particularly annoying if you were in the middle of debugging something, e.g. with elaborate querys, but were interrupted by something or someone and now you have to start all over again!
Fixing this is actually quite easy and has been explained in detail by Brian Chang.
Be aware though, that you probably should not implement this “fix” on any servers that are accessible from the outside. Doing this on your dev machine, like the one from my tutorial, is a good idea though and something I’ll definitely add in its next iteration!
