I'm sure there's probably a better way to do this, but uasort() sorts
an array using a callback provided callback function for item
comparisons -- which you can use to compare the specific key you want
to sort by. It seems like there should be a more generic way to do
this by providing the name of the key on which you want to sort.
$franchises['SCID1'] = SCNYC
$franchises['SCID1']['BusinessName'] = SuperCoups of NY City
$franchises['SCID1']['DistanceFromCustomer'] = 20
$franchises['SCID2'] = SCBUFF
$franchises['SCID2']['BusinessName'] = SuperCoups of Buffalo
$franchises['SCID2']['DistanceFromCustomer'] = 10
uasort($franchises, "cmp_distance");
function cmp_distance($a, $b) {
if($a['DistanceFromCustomer'] == $b['DistanceFromCustomer']) return 0;
return ($a['DistanceFromCustomer'] < $b['DistanceFromCustomer']) ? -1 :
1;
}

Hi All,
I have a multi-dimensional array such as:
$franchises['SCID1'] = SCNYC
$franchises['SCID1']['BusinessName'] = SuperCoups of NY
City
$franchises['SCID1']['DistanceFromCustomer'] = 20
$franchises['SCID2'] = SCBUFF
$franchises['SCID2']['BusinessName'] = SuperCoups
of Buffalo
$franchises['SCID2']['DistanceFromCustomer'] = 10
How can I sort this array so the businesses are sorted by the
DistanceFromCustomer key?
Thanks for the help in advance,
Tim
