Question

I am using php imap class.
In my box I have a lot of mail, but with this script I would retrieve only the unreaded mail.
How can I do it?

if ($mbox=imap_open( "{" . $mailserver . ":" . $port . "}INBOX", $user, $pass )) 
{
  echo "Connected\n"; 
} else { exit ("Can't connect: " . imap_last_error() ."\n");  echo "FAIL!\n";  }; 

if ($hdr = imap_check($mbox)) {
  $msgCount = $hdr->Nmsgs;
  echo "Ci sono ".$msgCount." mail";
} else {
  echo "Failed to get mail";
}

If I do

$overview=imap_fetch_overview($mbox,"1:$msgCount",0);

the script load to an infinity time.

The imap_search UNSEEN solution is not good because pop3 don’t use this flag.
So how can I do??????
Thanks a lot.

Answer 1

There is two way you can follow:

1. Looping through the messages

$count = imap_num_msg($connection);
for($msgno = 1; $msgno <= $count; $msgno++) {

    $headers = imap_headerinfo($connection, $msgno);
    if($headers->Unseen == 'U') {
       ... do something ... 
    }

}

2. Using imap_search

There’s a flag called UNSEEN which you can use to search for the unread emails. You would call the imap_search function with the UNSEEN flag like so:

$result = imap_search($connection, 'UNSEEN');

If you need to combine this with more search flags, for example searching for messages from [e-mail], you could do this:

$result = imap_search($connection, 'UNSEEN FROM "[e-mail]"');

For a complete list of the available flags, refer to the criteria section of the imap_search manual page on the PHP website (www.php.net/imap_search)
