Re: Sort two coupled arrays {my solution]

rsort(array_combine(array2, array1));

you should expect array(
'Personal Email' =3D> 75,
'USPS mail' =3D> 40,
'Personal Phone' =3D> 31,
'Web site' =3D> 31,
'Text Message' =3D> 31
)

logically, the items are your key but not the count of votes

Logically, combine_array() will work to combine the two arrays as you
said, as shown here:

http://www.webbytedd.com/bbbb/array-combine/

I've tried rsort(), but is does not solve the problem presented,
which was to sort the items depending upon their values.

Thus far, my solution is the only one that works.
