[FX.php List] Sorting multidimensional array

[Gjermund Gusland Thorsen]

I tend to rebuild the array... if it's only for display it might be a
clumsy solution, however if you would like to change more stuff around
or use the found set for washing data you would probably benefit from
constructing your own array based on the the current returned data
set.
