WordPress 在存储在数据库中时序列化数组和 objext。
您需要取消序列化 的值。例如：options
unserialize($array['options']);
WordPress 还包括一个执行相同工作的maybe_unserialize函数，但它包含一个仅取消序列化已序列化数据的条件。
maybe_unserialize($array['options']);
取消序列化后，它将返回以下数组：options

感谢您的重播，实际上我正在尝试从数据库中获取数据。当我尝试使用您的代码时，我遇到了错误，请解决我的查询 $retrieve_data = $wpdb->get_results（ “SELECT * FROM $table_name” ）;foreach （$retrieve_data as $key => $myvalue） { $properties = get_object_vars（$myvalue）; print_r（$properties）; }

请您更新您的问题。是 print_r（$properties）;从您的问题中返回数组？
