PHP中索引數組如何給對象賦值？

現有對象定義如下：

class User{    public $name;    public $age;    public $sex;    public $info;    public $school;    public $salary;}

現有索引數組如下:

$user = [    'name' => 'zhangsan',    'age' => 18,    'sex' => 1,    'school' => 'sysu',];

問題是，如何用這個數組給對象賦值，能不能用foreach進行賦值啊？現在我只會下面的實現，但是被說這個方法不好，應該用foreach，但是不知道怎麼用？

$user1 = new User();if(isset($user['name'])) $user1->name = $user['name'];if(isset($user['age'])) $user1->age = $user['age'];if(isset($user['sex'])) $user1->sex = $user['sex'];if(isset($user['info'])) $user1->info = $user['info'];if(isset($user['school'])) $user1->school = $user['school'];if(isset($user['salary'])) $user1->salary = $user['salary'];

foreach($user as $prop => $val) {    $user1->{$prop} = $val;}

    $userObj = new User();    foreach($user as $key => $value){        if(property_exists($userObj,$key)){            $userObj->$key = $value        }    }

$user = [    'name' => 'zhangsan',    'age' => 18,    'sex' => 1,    'school' => 'sysu',];$userobj = (object)$user
