[RESOLVED] reciprocal sorting of arrays

[sssphp]

I have 2 arrays that I want to keep sequentially in sync after one has been re-sorted. E.G.:

$array1 = array(1, 2, 3, 4, 5);
$array2 = array(a, b, c, d, e);

[code acts on $array1 so that it becomes]:

$array1 = array(3, 1, 5, 4, 2);

I need code that gives this result:

$array2(c, a, e, d, b);

This is probably pretty simple using the keys for each, but the code that re-sorts $array1 is SQL (i.e. it is a field of data values that re-sorts via 'ORDER BY').
I'm not sure then how I would retain the original keys in $array1 so I could apply them to $array2.

Could you use a multi-dimension array?

$data = array(array(1, 'a'),
              array(2, 'b'),
              array(3, 'c'),
              array(4, 'd'),
              array(5, 'e'));

Then you could sort $data based on the values of $data[n][0], and $data[n][1] would then stay with its associated value.

I don't think so...the two arrays get acted on independently. Maybe there's a way, but I don't know it.

You could combine the two arrays, so that the values of the first are used as keys of the combined array, and the values of the second are the values of the combined array. Then use [man]ksort[/man] or [man]uksort[/man] to sort the arrays while maintaining key association; finally using [man]array_keys[/man] and [man]array_values[/man] to seperate the result back into two arrays.

In short, there's bound to be a solution among the array functions.

Thanks all -- I found a solution for this.
