Question

我需要代码来搜索符合主题的电子邮件（它确实如此），但只返回在两个日期之间到达的电子邮件。我目前正在使用的代码是搜索SINCE，但即使这样也会返回比2013年1月20日更早的电子邮件：

$emailSearch = "SUBJECT \"PerformanceStatement ($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)) 
                        {

                                    'is_attachment' => false,
                                    'filename' => '',

                                    $fp = fopen($filename, "w+");

                                    $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;
}

我有什么想法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？

修改的没有任何建议我决定订购从最旧到最新的电子邮件，然后当我浏览每个电子邮件时，我从1开始编号。从那里我得到x最近或最老，等等。它没有回答这个问题，但它适用于我需要的。
