something like this:

$sort=array();
foreach($array as $key=>$v){$sort[$key]=$v['points'];}
sort($sort);
$newArray=array();
$i=0; $points=0;
foreach($sort as $key=>$v){
    $i++;
    if($v['points']>$points){$i++; $points=$v['points'];
    $newArray[$key]=$array['key'];
    $newArray[$key]['rank']=$i;
}
$array=$newArray;
