Hi gang: Here's the problem. Let's say you have a collection of arrays, such as: $a = array(); $b = array(); $c = array(); $d = array(); And then you populate the arrays like so: while(...)

    {
    $a[] = ...
    $b[] = ...
    $c[] = ...
    $d[] = ...
    }

Now, let's say you want to sort the $d array, but you also want the arrays $a, $b, and $c to be arranged in the same resultant order as

$d.

For example, please follow this: Before sort of $d: $a = [apple, banana, grape, orange] $b = [100, 2111, 198, 150] $c = [red, yellow, purple, orange] $d = [100, 300, 11, 50] After sort of $d: $a = [grape, orange, apple, banana] $b = [198, 150, 100, 2111] $c = [purple, orange, red, yellow] $d = [11, 50, 100, 300]

array_multisort($d, $a, $b, $c) should do what you want

That's even slicker than tedd_sort(). Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP
