'SimpleXMLElement' 的序列化不允许在会话 xml 值中插入错误 [英] 'Serialization of 'SimpleXMLElement' is not allowed Error insert in session xml value

问题描述

大家好，我有一个用 codeigniter 开发的网站.我正在解析从服务器检索的 xml，我想将返回值放入会话变量中.但是返回给我这个错误:

Hi all I have a site developed in codeigniter. I'm parsing an xml that I retrieve from a server and I want to put the return value into a session variable. But return me this error:

致命错误:未捕获的异常 'Exception' 带有消息 'SimpleXMLElement' 的序列化是不允许的

Fatal error: Uncaught exception 'Exception' with message 'Serialization of 'SimpleXMLElement' is not allowed

我的 vps 上的 PHP 版本是:PHP 版本 5.3.10-1ubuntu3.4

My PHP version on my vps is: PHP Version 5.3.10-1ubuntu3.4

这是我的代码:

$xml = new SimpleXMLElement(curl_exec($ch2));
$error2=curl_getinfo( $ch2, CURLINFO_HTTP_CODE );
curl_close($ch2);
foreach ($xml->DATA as $entry){
    $code_travco = $entry->attributes()->COUNTRY_CODE;
    $name_en =  $entry->COUNTRY_NAME;
    $newdata = array(
        'code'  => $code_travco,
        'name_en'     =>  $name_en
    );
    $this->session->set_userdata($code_travco.'_nation_en', $newdata);      
 } 

推荐答案

可以尝试在添加之前将其更改为字符串，例如:

may be try changing it to string before adding, like:

foreach ($xml->DATA as $entry){
    $code_travco = (string) $entry->attributes()->COUNTRY_CODE;
    $name_en =  (string) $entry->COUNTRY_NAME;
    $newdata = array(
        'code'  => $code_travco,
        'name_en'     =>  $name_en
    );
    $this->session->set_userdata($code_travco.'_nation_en', $newdata);      
 }
