多维数组排序

Array
(
    [0] => Array
        (
            [h_id] => 59
        )

    [9] => Array
        (
            [h_id] => 56
        )

)

foreach($where as $key=>$value){
         $id[$key]=$value["id"];        
}
array_multisort($where,$ids);

运行结果：

Array
(
    [0] => Array
        (
            [h_id] => 56
        )

    [1] => Array
        (
            [h_id] => 59
        )

)

 

$data=array(
  array("id"=>1,"name"=>4),
  array("id"=>1,"name"=>2),
  array("id"=>2,"name"=>3)
);
foreach($data as $key=>$value){
 $ids[$key]=$value["id"];
 $names[$key]=$value["name"]
}
array_multisort($data,$ids,$names);
print_r($data);

运行结果：

array(
    array("id"=>1,"name"=>2),
    array("id"=>1,"name"=>4),
    array("id"=>2,"name"=>3)
 );
