我该如何从这封电子邮件中获取附加的文件？
这封电子邮件是从苹果电脑发送的，并且电子邮件结构不像其他电子邮件（惊喜）……在这里，具有位置的部分比其他部分深一个维度。
脚本可以处理其中文件部分在第一维度上的所有其他电子邮件，但不能处理此类邮件。
$part->dparameters[0]->value 返回文件名，但是strlen($data)返回0
imap流
$structure = imap_fetchstructure($this->stream, $this->msgno);
if(isset($structure->parts)){
print_r($structure->parts);
$this->parse_parts($structure->parts);
}
function parse_parts($parts){
foreach($parts as $section => $part){
if(isset($part->parts)){
// some mails have one extra dimension
$this->parse_parts($part->parts);
}
elseif(isset($part->disposition)){
if(in_array(strtolower($part->disposition), array('attachment','inline'))){
$data = imap_fetchbody($this->stream, $this->msgno, $section+1);
echo $part->dparameters[0]->value.' '.strlen($data)."\n";
}
}
}
}
print_r
