在PHP中使用IMAP()获取最近的未读电子邮件计数 [英] Using IMAP () in PHP to get recent unread emails count

问题描述

我试图得到拒绝.来自gmail帐户的最新未读邮件.为此，我在Ubuntu系统中安装了IMAP，并尝试了一些PHP iMAP函数. 这是我到目前为止尝试过的.

/* connect to gmail */
$hostname = '{imap.gmail.com:993/imap/ssl}INBOX';
$username = '[e-mail]';
$password = 'user_password';

/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' .    imap_last_error());

现在我要说明我的所有尝试. 注意:我已经尝试过通过将新邮件发送到测试电子邮件ID来尝试每次尝试

Attempt_1:使用imap_search()

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

现在Attempt_1的输出为"false return"；

Attempt_2:使用imap_mailboxmsginfo()

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

当我向该ID发送了2封新邮件时，输出为最近:0"

Attempt_3:使用imap_status()

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

//最近输出:0

Attempt_4:再次将imap_search()与参数NEW配合使用

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

输出-错误的返回

那我错在哪里? 如何获得最近的未读电子邮件计数?

解决方案

此功能似乎有效:

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;
}

用法:

$hostname = '{imap.gmail.com:993/imap/ssl}INBOX';
$username = '[e-mail]';
$password = 'user_password';

$count = CountUnreadMail($hostname, $username, $password);

我无法为此功能索取全部功劳.它是对 PHP显示未读邮件数的回答比较呆滞的略加修改的版本.他的版本假定使用POP邮件.此版本需要完整的$hostname.我用自己的gmail帐户进行了测试，并正确报告了收件箱中的未读邮件数量.

PHP显示未读邮件计数具有一些相当不错的阅读材料.签出来.

希望这会有所帮助.

更新

发件人: Gmail是否支持所有IMAP功能?

Gmail IMAP1是IMAP的相当完整的实现，但是 当前不支持以下功能:

\Recent flags on messages.

经过验证: Gmail的Buggy IMAP实现

Gmail不处理标准的IMAP标志，例如"\ Deleted"， "\ Answered"和"\ Recent".

另请参见: Jyoti Ranjan的答案(如下)，以寻求可能的解决方案.

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 = '[e-mail]';
$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: "   . $check->Recent  . "<br />\n" ;
else
    echo "imap_check() failed: " . imap_last_error() . "<br />\n";
imap_close($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      . "<br />\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?

解决方案

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 = '[e-mail]';
$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".
