Use usort (stealing from php docs): function cmp($a['score'], $b['score']) { if ($a['score'] == $b['score']) {

       return 0;

} return ($a['score'] < $b['score']) ? -1 : 1; } $data = array(...); usort($data, "cmp");

This won't work for me as I have 500+ records to sort based on the score key.. looking at jochem's class now. Thanks

which wont help much - assuming what you say is true (why wont it work? have you tried it). sort method from the class:

    function sort()
    {
       if(count($this->sortKeys)) {
           usort($this->dataArray, array($this,"_sortcmp"));
       }
    }

Thanks jochem, I had a second look at it and I figured it out. I had problem implementing it with a class but now I have figured how to use it.

cheers, Jeffery
