int imap_uid ( resource imap_stream, int msg_number )

This function returns the UID for the given message sequence number. An UID is a unique identifier that will not change over time while a message sequence number may change whenever the content of the mailbox changes.

This function is the inverse of imap_msgno().

Список параметров

imap_stream: An IMAP stream returned by imap_open().

Please note that message_id in the header is NOT the UID - and its dangerous to use as many mail progs don't put a message id in

Another way to get the UID without using imap_uid that works with pop3:



$header = imap_headerinfo( $mbox, $msgno );

$UID = $header->message_id;

For those using a POP3 mailbox, this function, as noted, does not work.



One way around this is to use direct FTP communication with the mail server.  For example, the following function takes a mailbox/password and message sequence number, and from this returns the message UID.



function fetch_UID($account, $password, $message_number)

{

    $retval = 0;

    $fp = fsockopen($POPMAILSERVER, 110);

    if ($fp > 0)

    {

        $buf = fgets($fp, 1024);



        fputs($fp, "USER $account\r\n");

        $buf = fgets($fp, 1024);



        fputs($fp, "PASS $password\r\n");

        $buf = fgets($fp, 1024);



        fputs($fp, "UIDL $message_number\r\n");

        $retval=fgets($fp, 1024);



        fputs($fp, "QUIT\r\n");

        $buf = fgets($fp,1024);



        fclose($fp);

    }

    return substr($retval,6,30);

}



Note: 110 is the TCP port commonly associated with a POP3 mailbox.  Also the substr() function is used to trim the +OK and the message number from the beginning of the server's response.



I'm sure there are other (better) ways to do this.  But after a fruitless search of the internet, this is what I came up with, and it seems to work for me.
