我需要代码来搜索符合主题的电子邮件（确实如此），但只返回在两个日期之间到达的电子邮件。我目前使用的代码是搜索 SINCE，但即使这样也会返回早于 2013 年 1 月 20 日的电子邮件：
$emailSearch = "SUBJECT \"PerformanceStatement ($orgSaboName)\" SINCE \"20-Jan-2013\"";
function downloadDataSearch($emailAddress, $reportUrl, $reportType, $emailSearch)
{
$result = "error";
// DOWNLOAD DATA
// the max time allows for the email to download
set_time_limit(30000);
// connect to gmail with your credentials
$hostname = '{imap.gmail.com:993/imap/ssl}INBOX';
$username = $emailAddress; # e.g somebody@gmail.com
$password = '*************';
// try to connect
$inbox = imap_open($hostname,$username,$password) or die('Cannot download information: ' . imap_last_error());
$max_emails = 1;
/* get all new emails. If set to 'ALL' instead
* of 'NEW' retrieves all the emails, but can be
* resource intensive, so the following variable,
* $max_emails, puts the limit on the number of emails downloaded.
*
*/
$emails = imap_search($inbox, "$emailSearch");
// if any emails found, iterate through each email
if($emails > 0)
{
$count = 1;
// put the newest emails on top
//rsort($emails);
// for every email...
foreach($emails as $email_number)
{
// get information specific to this email
$overview = imap_fetch_overview($inbox,$email_number,0);
// get mail structure
$structure = imap_fetchstructure($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, $i+1);
// 4 = QUOTED-PRINTABLE encoding
if($structure->parts[$i]->encoding == 3)
{
$attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
}
// 3 = BASE64 encoding
elseif($structure->parts[$i]->encoding == 4)
{
$attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
}
//imap_delete($inbox,$email_number);
//imap_mail_move($inbox, $email_number,'[Gmail]/Bin');
}
}
}
// iterate through each attachment and save it
foreach($attachments as $attachment)
{
if($attachment['is_attachment'] == 1)
{
// SCAN REPORT SET OUTSIDE OF FUNCTION
$filename = $reportUrl;
if(empty($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.
*/
$fp = fopen($filename, "w+");
fwrite($fp, $attachment['attachment']);
fclose($fp);
$result = "success";
}
}
// Only include if you have set $max_emails above //
// if($count++ >= $max_emails) break;
}
}
// close the connection
imap_close($inbox,CL_EXPUNGE);
return $result;
}
任何想法我做错了什么让它返回自特定日期以来的第一封电子邮件或在两个日期之间搜索的方式？
编辑 在没有任何建议的情况下，我决定将生成的电子邮件从最旧到最新排序，然后当我浏览每封邮件时，我从 1 开始对它们进行编号。从中我得到 x 最近或最旧等。它没有回答这个问题，但它适用于我需要的东西。
