Question

I have the following array that I need to have sorted from highest score to lowest.

Array
(
    [0] => Array
        (
            [team id] => 5
            [score] => 52
            [fouls] => 0
        )

    [1] => Array
        (
            [team id] => 4
            [score] => 47
            [fouls] => 0
        )

    [2] => Array
        (
            [team id] => 8
            [score] => 46
            [fouls] => 6
        )

    [3] => Array
        (
            [team id] => 1
            [score] => 46
            [fouls] => 5
        )

    [4] => Array
        (
            [team id] => 9
            [score] => 46
            [fouls] => 3
        )

)

The array above has been sorted already with this function:

function sortByOrder($a, $b){
    $Return = $b['score'] - $a['score'];
    return $Return;
}

usort($Array, 'sortByOrder');

Which seems to work fine since the array with the highest score goes up the list.

However, some teams have equal scores but have committed some fouls. How can I adjust the function to also take the fouls into account when a score equals another score? The team with the least fouls should be placed higher.

Looking forward for creative solutions!

Thanks in advance.

Answer 1

You just have to update your function sortByOrder().

Basically:

function sortByOrder($a, $b){
  if ($b['score'] == $a['score'])
    return $a['fouls'] - $b['fouls'];
  else
    return $b['score'] - $a['score'];
}
