sort_array() - sort an array

Synopsis

mixed *sort_array( mixed *arr, string fun, object ob );
.EI
Description
.SP 5 5
Returns an array with the same elements as `arr', but quicksorted in
descending order according to the rules in `ob->fun()'. `ob->fun()' will
be passed two arguments for each call. It should return -1, 0, or 1,
depending on the relationship of the two arguments (lesser, equal to,
greater than).
Here are two common forms for the compare function to take:
int compare(string one, two)
{
return strcmp(one, two);
}
int compare(int one, two)
{
return (one - two);
}
