Question

我能够使用序列化数据正确更新数据库，但我无法正确检索它。当我尝试从数据库中反序列化并从数据库中检索它时，它只回显Array。

以下是我使用序列化进行更新的方法：

$query ="Update dashboard_widget_users set dashboard_widget_users.configuration='".serialize($tmp)."' where dashboard_widget_users.dsnr_yw_user =12 and dashboard_widget_users.dsnr_dashboard_widget=1";

结果：

a:4:{i:0;s:30:""Anzahl_Fahrzeuge_ohne_Bilder"";i:1;s:22:""Fahrzeuge_ohne_Preis"";i:2;s:23:""Fahrzeuge_mit_Fehlern"";i:3;s:19:""Herausforderungen"";}

这就是我尝试unserialize()并从数据库中检索它但我没有正确输出的方法：

$config= unserialize($row['configuration']);
echo $config['configuration'];

这是我的代码：

if($param['aktion'] == 'save-widget-vehicle')
{
    $page['register-fahrzeuge'] = array(
        1   => array( 'Fahrzeug','aktiv',$page['script'],''),
        0   => array( 'Edit-Fahrzeug','enabled',$page['script'],'',''), 
    );

        $opts = !empty($param['filterOpts']) ? $param['filterOpts'] : array();

      $tmp = array();
      foreach ($opts as $opt) {
            $tmp[] = '"'.$opt.'"';
      }
      $data = array();

     $query ="UPDATE dashboard_widget_users w SET w.configuration=\"".mysql_real_escape_string(serialize($tmp))."\" WHERE w.dsnr_yw_user =12 AND w.dsnr_dashboard_widget=1";            
     $result = mysql_query($query, $myConnection);

        $html = '<table width="538" cellspacing="0" cellpadding="0" border="0">
                <tr>
                    <td>
                        <div>'.CreateRegister($page['register-news']).'</div>
                        '.CreateMessage().'

Answer 1

你总是根据去的位置转义字符串，所以在将放入数据库之前对值使用mysqli_real_escape_string（） - 而不是在检索它时来自数据库：

 $row=mysqli_fetch_assoc($result);
 $config=unserialize($row['config']);

您已使用jsonserializer对此进行了标记 - 但您在此处使用的是PHP序列化。

Answer 2

只需要将所有内容反序列化。为什么mysql_escape_string？

如果

，

$dbresult = 'a:4:{i:0;s:30:""Anzahl_Fahrzeuge_ohne_Bilder"";i:1;s:22:""Fahrzeuge_ohne_Preis"";i:2;s:23:""Fahrzeuge_mit_Fehlern"";i:3;s:19:""Herausforderungen"";}';
$data = unserialize($dbresult);
print_r($data);

$query ="UPDATE dashboard_widget_users w SET w.configuration=\"".mysql_real_escape_string(serialize($tmp))."\" WHERE w.dsnr_yw_user =12 AND w.dsnr_dashboard_widget=1";
