A simple method to realize php two-dimensional array sequencing _php skills

In this paper, we describe a simple method to realize php two-dimensional array sorting. Share to everyone for your reference, specific as follows:

function Multi_compare ($a, $b)
{
  $val _arr = Array (
      ' Gold ' => ' ASC ',
      ' silver ' => ' desc '// Additional sorting criteria can also be added
  );
  foreach ($val _arr as $key => $val) {
    if ($a [$key] = = $b [$key]) {
      continue;
    }
    Return (($val = = ' desc ') -1:1) * (($a [$key] < $b [$key]) -1:1);
  return 0;
}
$arr = Array (
  ' Gold ' =>1, ' Silver ' =>2),
  array (' Gold ' =>8, ' Silver ' =>10),
  Array (' Gold ' =>8, ' Silver ' =>8),
  array (' Gold ' =>2, ' Silver ' =>1),
);
Uasort ($arr, ' multi_compare ');
Print_r ($arr);

The results of the operation are as follows:

Array
(
  [0] => array
    (
      [gold] => 1
      [silver] => 2
    )
  [3] => array
    (
      [ Gold] => 2
      [silver] => 1
    )
  [1] => Array
    (
      [gold] => 8
      [silver] =>
    )
  [2] => Array
    (
      [Gold] => 8
      [silver] => 8
    )
)
