Handling ties when ranking from the highest to the lowest

Question

I am trying to make a ranking manager for a small project.The totals are stored in the database.I can easily get the max and min using mysql and also arrange the records descend

Answer 1

$data = array(
  'A'=>19,'B'=>18,'C'=>17,'D'=>17,'E'=>16,'F'=>15
);

$rank = 0;
$lastScore = PHP_INT_MAX;
foreach( $data as $name=>$score ) {
  if ( $lastScore !== $score ) {
    $lastScore = $score;
    $rank += 1;
  }
  printf("%s %d (%d)\n", $name, $score, $rank);
}

prints

A 19 (1)
B 18 (2)
C 17 (3)
D 17 (3)
E 16 (4)
F 15 (5)
