我正在阅读来自php的邮件，邮件中有xls或xlsx文件，所以一旦我下载了它就会被下载，但是当我尝试读取xls或xlsx文件时就这样了
$email_number = $emails[count($emails)-$k];
/* get information specific to this email */
$overview = imap_fetch_overview($connection,$email_number,0);
$message = imap_fetchbody($connection,$email_number,2);
/* get mail structure */
$structure = imap_fetchstructure($connection, $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' => '',
'typeval' => $structure->parts[$i]->type
);
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($connection, $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 */
$j=0;
foreach($attachments as $attachment)
{
if($attachment['is_attachment'] == 1)
{
$filename='';
if(trim($attachment['filename'])!="")
$filename=trim($attachment['filename']);
elseif(trim($attachment['name'])!="")
$filename=trim($attachment['name']);
$ext = strtolower(substr(trim($filename), strrpos(trim($filename), '.') + 1));
//$filename = $attachment['filename'];
$filename = str_replace(" ","-",strtolower($companyArray[$excelSheet])).$j.$k.'.'.$ext;
if(empty($filename)) $filename = $attachment['filename'];
if(empty($filename)) $filename = time() . ".dat";
$folder = "download";
if(!is_dir($folder))
{
mkdir($folder);
}
$fp = fopen("./". $folder ."/". $filename, "w+");
$data = strtr($attachment['attachment'], array('-' => '+', '_' => '/'));
fwrite($fp, $data);
fclose($fp);
chmod("./". $folder ."/". $filename, 0644);
$j++;
}
}
请帮助我解决此问题。以下是我的代码
