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 (($val == 'desc')?-1:1) * (($a[$key] < $b[$key]) ? -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);
运行结果如下：
Array
(
[0] => Array
(
[gold] => 1
[silver] => 2
)
[3] => Array
(
[gold] => 2
[silver] => 1
)
[1] => Array
(
[gold] => 8
[silver] => 10
)
[2] => Array
(
[gold] => 8
[silver] => 8
)
)
