You need to use a order by query

$sql="select * from table order by rank desc";
$point =1;
$result = mysql_query($sql); 
$tableResult = array();
while($arrayresult =mysql_fetch_array($result))
{
    $tableResult[] = array('id'=>$arrayresult['id'],'rank'=>$arrayresult['rank'],'point'=>$point);
    $point= $point+1;
}
