sort associative array on values

[Jan Hanselaer]

Hi,

It is easy to output a associative array sorted on his keys but does anyone 
know how to do it with the values sorted?

I use associative arrays for frequency tables (for char[] en char) and I 
would like to output those sorted by value, and if that would be possible, 
also by key for equal values. Anyone ever tried this of has any ideas?

Thanks in advance!
Jan
