我正在尝试使用 imap 从电子邮件中获取电子邮件附件，
该脚本适用于大多数电子邮件，但一个发件人附件似乎有问题，无法检索 pdf 附件。
我的代码在这里
$hostname = '{mail.testserver.com:993/tls}INBOX';
$username = 'test@testserver.nl';
$password = 's1M@F1225224';
/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Email Server: ' . imap_last_error());
/* grab emails */
$emails = imap_search($inbox,'FROM "info@test.com"');
count($emails);
/* if emails are returned, cycle through each... */
if($emails) {
/* begin output var */
$output = '';
$io=0;
/* put the newest emails on top */
rsort($emails);
/* for every email... */
foreach($emails as $email_number){
echo $io++;
echo '<br/>';
$int='';
/* get information specific to this email */
$overview = imap_fetch_overview($inbox,$email_number,0);
$message = imap_fetchbody($inbox,$email_number,1);
$headerx = imap_headerinfo($inbox,$email_number,0);
// get first mails header
$structure = imap_fetchstructure($inbox, $email_number);
//var_dump( $structure );
$attachments = array();
/* if any attachments found... */
if(isset($structure->parts) && count($structure->parts))
{
for($i = 0; $i < count($structure->parts); $i++)
{
echo 'dump of mail structure <pre>';
var_dump($structure->parts[$i]);
echo '<pre>';
$attachments[$i] = array(
'is_attachment' => false,
'filename' => '',
'name' => '',
'attachment' => ''
);
if($structure->parts[$i]->ifdparameters)
{
//dparameters
foreach($structure->parts[$i]->ifdparameters as $object)
{
echo $object->attribute;
if(strtolower($object->attribute) == 'filename')
{
$attachments[$i]['is_attachment'] = true;
$attachments[$i]['filename'] = $object->value;
}
}
}
if($structure->parts[$i]->ifparameters)
{
foreach($structure->parts[$i]->parameters as $object)
{
if(strtolower($object->attribute) == 'name')
{
$attachments[$i]['is_attachment'] = true;
$attachments[$i]['name'] = $object->value;
}
}
}
if($attachments[$i]['is_attachment'])
{
$attachments[$i]['attachment'] = imap_fetchbody($inbox, $email_number, $i+1);
/* 3 = BASE64 encoding */
if($structure->parts[$i]->encoding == 3)
{
$attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
}
/* 4 = QUOTED-PRINTABLE encoding */
elseif($structure->parts[$i]->encoding == 4)
{
$attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
}
}
}
}
echo '<pre>';
var_dump($attachments);
echo '<pre>';
break;
}
结构部分的var dump $structure->parts[$i]

有人知道这个邮件内容或脚本有什么问题吗，有没有办法获取附件，非常感谢
我认为附件对象结构与其他邮件不同，但我不确定如何获取它
最佳答案
检查您尝试附加的文件的pdf附件的大小，它可能超过了php.ini允许的限制
关于某些电子邮件无法访问 PHP IMAP 电子邮件附件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49205973/
