推荐答案

您好，您的查询从数据库中获取数据时，您需要先对数据进行反序列化，这是序列化的数据，当我们从数据库中获取它时，我们需要将其取消序列化.

Hello you need to unserealize the data first when your query get data from database, That is serealized data and when we get it from db we need to unserealize it.

 global $wpdb;
    $mylink = $wpdb->get_results("SELECT option_value FROM wp_options WHERE option_id=1223",ARRAY_A);

   $raw = stripslashes_deep($mylink);
  $data = $raw[0]['option_value'];
  $datas = unserialize($data);
  foreach ($datas as $key => $value) {
    print_r($value);
  }
