php二维数组排序
$ary=array(array("ID"=>13,"name"=>"kitty"),array("ID"=>22,"name"=>"sony"),array("ID"=>17,"name"=>"picker"));
我想对其按照ID升序调整一维数组的顺序，结果为
array(array("ID"=>13,"name"=>"kitty"),array("ID"=>17,"name"=>"picker")，array("ID"=>22,"name"=>"sony"));
应该怎么写？
------解决方案--------------------
前两天才有人问过...
PHP code
$ary=array(array("ID"=>13,"name"=>"kitty"),array("ID"=>22,"name"=>"sony"),array("ID"=>17,"name"=>"picker"));
foreach ($ary as $key => $value) {
$Id[$key] =$value['ID'];
$Name[$key] = $value['name'];
}
array_multisort($Id, SORT_ASC,$ary);
print_r($ary);
