我试图让我的程序下载所有文件附件，但出于某种原因，它不会下载所有文件附件只下载某个文件附件。这是代码：
<?php
set_time_limit(3000);
$hostname = '{someoutlookemail.outlook.com:993/imap/ssl}INBOX';
$username = 'someoutlookemail@outlook.com';
$password = 'apass';
/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error());
/* grab emails */
$emails = imap_search($inbox,'ALL');
$max_emails = 16;
/* if emails are returned, cycle through each... */
if($emails) {
$count = 1;
/* begin output var */
$output = '';
/* put the newest emails on top */
rsort($emails);
/* for every email... */
foreach($emails as $email_number) {
/* get information specific to this email */
$overview = imap_fetch_overview($inbox,$email_number,0);
$message = imap_fetchbody($inbox,$email_number,1.1);
$structure = imap_fetchstructure($inbox,$email_number);
$attachments = array();
/* if any attachments found... */
if(isset($structure->parts) && count($structure->parts))
{
for($i = 0; $i < count($structure->parts); $i++)
{
$attachments[$i] = array(
'is_attachment' => false,
'filename' => '',
'name' => '',
'attachment' => ''
);
if($structure->parts[$i]->ifdparameters)
{
foreach($structure->parts[$i]->dparameters as $object)
{
if(strtolower($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']);
}
}
}
}
/* iterate through each attachment and save it */
foreach($attachments as $attachment)
{
if($attachment['is_attachment'] == 1)
{
$filename = $attachment['name'];
if(empty($filename)) $filename = $attachment['filename'];
if(empty($filename)) $filename = time() . ".dat";
/* prefix the email number to the filename in case two emails
* have the attachment with the same file name.
*/
$fp = fopen("./" . $email_number . "-" . $filename, "w+");
fwrite($fp, $attachment['attachment']);
fclose($fp);
}
}
if($count++ >= $max_emails) break;
/* output the email header information */
$output.= '<p><div class="toggler '.($overview[0]->seen ? 'read' : 'unread').'">';
$output.= '<p>Subject: <span class="subject">'.$overview[0]->subject.'</span> ';
$output.= '<p>From: <span class="from">'.$overview[0]->from.'</span>';
$output.= '<p>Date: <span class="date">on '.$overview[0]->date.'</span>';
$output.= '</div>';
/* output the email body */
$output.= '<p>Message:<div class="body">'.$message.'';
$output.= '<p>attachment:'.$filename.'';
$output.= '<table><tr><hr size="1" width="100%%" noshade color="black" ></tr></table>';
}
echo $output;
}
/* close the connection */
imap_close($inbox);
?>
怎么了？我试图检查我的所有代码，我不明白为什么它只下载一些，我现在下载相同类型的文件（.xml），其中一个下载，另一个没有，下载的人有1mb大小，另一个600kb，请帮助，我到处搜索，我找不到解决方案。

你的脚本对我来说很好，所有文件都在下载。唯一的问题是没有正确显示，当你回显输出时，你应该迭代附件。像这样的东西
<?php
set_time_limit(3000);
/* try to connect */
/* if emails are returned, cycle through each... */
if($emails) {
$count = 1;
/* begin output var */
$output = '';
/* put the newest emails on top */
rsort($emails);
/* for every email... */
foreach($emails as $email_number) {
/* get information specific to this email */
$overview = imap_fetch_overview($inbox,$email_number,0);
$message = imap_fetchbody($inbox,$email_number,1.1);
$structure = imap_fetchstructure($inbox,$email_number);
$attachments = array();
/* if any attachments found... */
if(isset($structure->parts) && count($structure->parts))
{
for($i = 0; $i < count($structure->parts); $i++)
{
$attachments[$i] = array(
'is_attachment' => false,
'filename' => '',
'name' => '',
'attachment' => ''
);
if($structure->parts[$i]->ifdparameters)
{
foreach($structure->parts[$i]->dparameters as $object)
{
if(strtolower($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']);
}
}
}
}
/* iterate through each attachment and save it */
foreach($attachments as $key=>$attachment)
{
if($attachment['is_attachment'] == 1)
{
$filename = $attachment['name'];
if(empty($filename)) $filename = $attachment['filename'];
if(empty($filename)) $filename = time() . ".dat";

*/

}
}
if($count++ >= $max_emails) break;
/* output the email header information */
