Question

大家好我有一个在codeigniter中开发的网站。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。但是请回答这个错误：

致命错误：不允许带有“序列化'SimpleXMLElement'消息的未捕获异常'异常'

我的vps上的PHP版本是： PHP版本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);      
 }

Answer 1

可能会尝试在添加之前将其更改为字符串，例如：

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);      
 }

'不允许序列化'SimpleXMLElement'错误插入会话xml值
