The content of this article is to share with you how to sort a certain field in one-dimensional array in PHP two-dimensional array. It has certain reference value. Friends in need can refer to it
The data in the database obtained here
public function hot_sort(){
$type = input('type');
$list = $this->get_hot_sort($type);
$res = $list->data;
$re = $this->object_array($res);
foreach ($re as $k=>$v){
$data= Db::name('merchants')->field('share_num')->where(['gl_merchants_id'=>$v['user_id']])->find();
$re[$k]['share_num'] = $data['share_num'];
}
$result = $this->quick_sort($re);
//这里调用方法根据某个字段进行排序 success($result);
}====================================== =====================================
方法进行排序 /**
* @param $arrUsers
* @return mixed
*二维数组某个字段进行排序
*/
function quick_sort($arrUsers)
{
$sort = array(
'direction' => 'SORT_DESC', //排序顺序标志 SORT_DESC 降序；SORT_ASC 升序
'field' => 'share_num', //排序字段
);
$arrSort = array();
foreach($arrUsers AS $k => $v){
foreach($v AS $key=>$value){
$arrSort[$key][$k] = $value;
}
}
if($sort['direction']){
array_multisort($arrSort[$sort['field']], constant($sort['direction']), $arrUsers);
}
return $arrUsers;
}
