Well, the only obvious way I can think of is to use a global variable to set the array index you want to sort by -- something like:
function cmp ($a, $b) {
global $field;
return strcmp($a[$field], $b[$field]);
}
$field = "divname";
usort($array, "cmp");
$field = "divid";
usort($array, "cmp");
I haven't tested this, but I think it should work...!
Cheers!
