本文实例讲述了PHP二维数组排序简单实现方法。分享给大家供大家参考,具体如下:

function multi_compare($a, $b)
{
  $val_arr = array(
      'gold'=>'asc',
      'silver'=>'desc'//还可以增加额外的排序条件
  );
  foreach($val_arr as $key => $val){
    if($a[$key] == $b[$key]){
      continue;
    }
    return (($val == 'desc')&#63;-1:1) * (($a[$key] < $b[$key]) &#63; -1 : 1);
  }
  return 0;
}
$arr = array(
  array('gold'=>1, 'silver'=>2),
  array('gold'=>8, 'silver'=>10),
  array('gold'=>8, 'silver'=>8),
  array('gold'=>2, 'silver'=>1),
);
uasort($arr, 'multi_compare');
print_r($arr);

  [0] => Array
    (
      [gold] => 1
      [silver] => 2
    )
  [3] => Array
    (
      [gold] => 2
      [silver] => 1
    )
  [1] => Array
    (
      [gold] => 8
      [silver] => 10
    )
  [2] => Array
    (
      [gold] => 8
      [silver] => 8
    )
)
