PHP 数组对象 按照某个字段进行排序

Posted 2021-02-12

function sort($oba, $obb){
        //如果是对象
        if($oba->grade < $obb->grade){
            return 1;
        }elseif ($oba->grade == $obb->grade){
            return ($oba->during <= $obb->during) ? 1 : -1;
        }

        //如果是数组
        //if($oba[\'grade\'] < $obb[\'grade\']){
        //   return 1;
        //}elseif ($oba[\'grade\'] == $obb[\'grade\']){
        //  return ($oba[\'during\'] <= $obb[\'during\']) ? 1 : -1;
        //}
    }
    usort($info,\'sort\');

如果是在框架中使用（使用匿名函数操作）

usort($datas,function($oba,$obb){
            if($oba[\'is_checkin\'] < $obb[\'is_checkin\']){
                return 1;
            }elseif ($oba[\'is_checkin\'] == $obb[\'is_checkin\']){
                return ($oba[\'is_checkin\'] <= $obb[\'is_checkin\']) ? 1 : -1;
            }
        });
