一个选择排序算法

$arr = [0,4,8,3,2,5,6,1,9,7];

function select_sort($data){
    $sorted = [];
    $total = count($data);
    for($i = 0; $i<$total-1; $i++){
        for($j = $total-1; $j>$i; $j--){
            if ($data[$i] > $data[$j]){
                $tmp = $data[$i];
                $data[$i] = $data[$j];
                $data[$j] = $tmp;
            }
        }
    }
    return $data;
