PHP - 将对象数组转换为可用对象

Question

我有一个包含状态对象的数组，这些状态对象包含一个类似对象的数组，还包含注释对象

我的问题是，现在我的数组中有对象，如何将它们拉出来？这样我以后可以将它们保存到数据库中。

感谢您的帮助

Array
(
    [0] => cStatus Object
        (
            [statusId:cStatus:private] => 123123123
            [message:cStatus:private] => powpowpow
            [updated_time:cStatus:private] => 2011-01-27T15:52:48+0000
            [likes:cStatus:private] => Array
                (

您可以使用foreach和各个对象的访问属性进行保存。我假设您使用的是getter和setter方法，因为您的所有属性都是私有的。使用foreach提供“as”关键字，以便在循环执行时为每个单独的对象实例创建别名。

<?foreach($obj as $status){
  $status_text = $status->getMessage();
  //save this to database using your favored method;
  $comments = $status->getComments();
  //nest the foreach for all the comments to save them as well, if you like
  foreach($comments as $comment){
   //Save $comment here as well
  }
}
?>

这对于像您这样的复杂嵌套对象尤其方便，因为单个迭代器可以访问公共方法和属性，以便于操作，例如保存到数据库。
