 "小明",

  ),
  array(
    'name' => "小华",
    'score' => 92,
  ),

var_dump($arr);
$score=array_column($arr, 'score');
var_dump($score);
?>

$score=array_column($arr, 'score');
var_dump($score);

$max=max($score);
echo "score列的最大值为 $max";

$score=array_column($arr, 'score');
var_dump($score);

$max=max($score);
echo "score列的最大值为 $max 
";

$min=min($score);
echo "score列的最小值为 $min";

array_column(array,column_key,index_key);

max(array_values);

or

max(value1,value2,...);

min(array_values);

or

min(value1,value2,...);
