Using IMAP () in PHP to get recent unread emails count

问题:

I am trying to get no. of recent unread mails from a gmail account.For this I have installed IMAP in my Ubuntu system and tried some PHP iMAP functions. Here are what i have tried till now.

/* connect to gmail */ $hostname = '{imap.gmail.com:993/imap/ssl}INBOX'; $username = 'user@gmail.com'; $password = 'user_password';  /* try to connect */ $inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' .    imap_last_error());

Now I am stating all my attempts. NB - I have tried each attempt by sending new mails to the testing email id

Attempt_1: Using imap_search()

$recent_emails = imap_search($inbox,'RECENT'); if ($recent_emails)    echo count($recent_emails); else    echo "false return"; imap_close($inbox);

Now Output of Attempt_1 is "false return";

Attempt_2: Using imap_mailboxmsginfo()

$check = imap_mailboxmsginfo($inbox); if ($check)     echo "Recent: "   . $check->Recent  . "
\n" ; else     echo "imap_check() failed: " . imap_last_error() . "
\n"; imap_close($inbox);

Here the output is Recent:0 while I have sent 2 new mails to this id

Attempt_3: using imap_status()

$status = imap_status($inbox, $hostname, SA_ALL); if ($status)   echo "Recent:     " . $status->recent      . "
\n"; else   echo "imap_status failed: " . imap_last_error() . "\n";

//Output Recent:0

Attempt_4: Using Using imap_search() Again with parameter NEW

$recent_emails = imap_search($inbox,'NEW'); if ($recent_emails)    echo count($recent_emails); else    echo "false return"; imap_close($inbox);

Output - false return

So Where Am I WRONG? How can I get the recent unread emails count?

This function seems to work:

function CountUnreadMail($host, $login, $passwd) {     $mbox = imap_open($host, $login, $passwd);     $count = 0;     if (!$mbox) {         echo "Error";     } else {         $headers = imap_headers($mbox);         foreach ($headers as $mail) {             $flags = substr($mail, 0, 4);             $isunr = (strpos($flags, "U") !== false);             if ($isunr)             $count++;         }     }      imap_close($mbox);     return $count; }

Usage:

$hostname = '{imap.gmail.com:993/imap/ssl}INBOX'; $username = 'user@gmail.com'; $password = 'user_password';  $count = CountUnreadMail($hostname, $username, $password);

I can’t claim full credit for this function. It’s a slightly edited version of sdolgy’s answer to PHP Displaying unread mail count. His version assumed POP mail. This version requires the full $hostname. I tested it with my own gmail account and it correctly reported the number of unread messages I had in my inbox.

PHP Displaying unread mail count has some pretty good reading material. Check it out.

Hope this helps.

UPDATE

From: Does Gmail support all IMAP features?

Gmail IMAP1 is a fairly complete implementation of IMAP, but the following features are currently unsupported:

\Recent flags on messages.

Verfied at: Gmail's Buggy IMAP Implementation

Gmail doesn't handle standard IMAP flags, such as "\Deleted", "\Answered", and "\Recent".

I have solved it using database,This is how I have done it.

1.I made a column in users table, for ex- 'email_max_uid' INT(11) NOT NULL default 0

2.When a user loads this page first, using my sql query I retrieved the value of 'email_max_uid' of that particular users 3.connect to his gmail account automatically and got the unread mails and total mails

$inbox = imap_open('{imap.gmail.com:993/imap/ssl}INBOX','user's email id','user's password') or die('Cannot connect to Gmail: ' . imap_last_error());         $unread_emails = imap_search($inbox,'UNSEEN');         $emails = imap_search($inbox
