web系统获取邮箱邮件，获取qq邮件内容时内容区图片获取不到/解析不出来，163邮箱的内容区图片可以正常获取到，但163邮箱的附件名称乱码（汉字变为数字+字母）

获取代码：
public function GetAttach($mid,$path) // Get Atteced File from Mail
{
if(!$this->marubox)
return false;
$struckture = imap_fetchstructure($this->marubox,$mid);
$files=array();
if($struckture->parts)
{
foreach($struckture->parts as $key => $value)
{
$enc=$struckture->parts[$key]->encoding;
//取邮件附件
if($struckture->parts[$key]->ifdparameters)
{
//命名附件,转码
$name=$this->decode_mime($struckture->parts[$key]->dparameters[0]->value);
$extend =explode("." , $name);
$file['extension'] = $extend[count($extend)-1];
$file['pathname'] = $this->setPathName($key, $file['extension']);
$file['title'] = !empty($name) ? htmlspecialchars($name) : str_replace('.' . $file['extension'], '', $name);
$file['size'] = $struckture->parts[$key]->dparameters[1]->value;
// $file['tmpname'] = $struckture->parts[$key]->dparameters[0]->value;
if(@$struckture->parts[$key]->disposition=="ATTACHMENT")
{
$file['type'] = 1;
}
else
{
$file['type'] = 0;
}
