在意大利存在PEC邮件。 经典的PEC邮件具有以下结构

我们可以看到我们有三个嵌套部分。 从这个答案开始 https://stackoverflow.com/a/11546986/10850224
为此，我要构建一个递归函数
function getAttachment($structure,$livel){
global $attachments;
global $email_number;
global $inbox;
global $index;
if(isset($structure->parts) && count($structure->parts)) {
for($i = 0; $i < count($structure->parts); $i++) {
if(isset($structure->parts[$i]->parts)){
$livel++;
getAttachment($structure->parts[$i],$livel);
}
$attachments[$i] = array(
'is_attachment' => false,
'filename' => '',
'name' => '',
'attachment' => '',
'level'=>$livel);
if($structure->parts[$i]->ifdparameters) {
foreach($structure->parts[$i]->dparameters as $object) {
if(strtolower($object->attribute) == 'filename') {
echo $object->value;
$attachments[$i]['is_attachment'] = true;
$attachments[$i] ['attachment']= $object->value;
echo "INDEX".$index."<br>";
}
}
}
if($structure->parts[$i]->ifparameters) {
foreach($structure->parts[$i]->parameters as $object) {
if(strtolower($object->attribute) == 'name') {
$attachments[$i]['is_attachment'] = true;
$attachments[$i] ['attachment']= $object->value;
echo "INDEX".$index."<br>";
}
}
}
if($attachments[$i]['is_attachment']) {
$str="1.3";
$attachments[$i]['attachment'] = imap_fetchbody($inbox, $email_number, $str);
if($structure->parts[$i]->encoding == 3) { // 3 = BASE64
$attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
}
elseif($structure->parts[$i]->encoding == 4) { // 4 = QUOTED-PRINTABLE
$attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
}
}
}
}
}
但是此功能无法获取正确的正文
获得所有附件的正确身体是什么
