AFAIK, there's no one-liner answer here. the usort() family of functions
pass either the key or the value, but never both.
I think you'll have to write this up yourself... depending on your data, you
may find that ksort() will get it 95% in-place, and a quick custom bubble
sort will get you the rest of the way. Or you could just code up your own
quicksort.
Alternatively, if you tweaked your data so it was a numerically-ordered
array of arrays, eg
array(array('key','value'),array('key','value'),array('key','value'))
instead of
array('key'=>'value','key'=>'value','key'=>'value')
then usort() would become a useful solution.
BTW, what's the data source? If it's coming from a SQL query, you can sort
the data on the way in and solve the problem that way.
