如何通過 PHP IMAP 從 Gmail 服務器讀取電子郵件

Question

我正在嘗試使用 PHP IMAP 讀取來自 Gmail 服務器的所有電子郵件。

我有以下配置：

$hostname = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX';
$username = 'email';
$password = 'pass';

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

var_dump($inbox);exit;

我收到 PHP 警告和通知：

imap_open(): 無法打開流 {imap.gmail.com:995/imap/ssl/novalidate-cert}INBOX

未知：無法連接到 imap.gmail.com，993：在第 0 行的未知中超時（errflg=2）

請幫忙

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

// search and get unseen emails, function will return email ids
$emails = imap_search($inbox,'UNSEEN');

$output = '';

foreach($emails as $mail) {

    $headerInfo = imap_headerinfo($inbox,$mail);

    $output .= $headerInfo->subject.'<br/>';
    $output .= $headerInfo->toaddress.'<br/>';
    $output .= $headerInfo->date.'<br/>';
    $output .= $headerInfo->fromaddress.'<br/>';
    $output .= $headerInfo->reply_toaddress.'<br/>';

    $emailStructure = imap_fetchstructure($inbox,$mail);

    if(!isset($emailStructure->parts)) {
         $output .= imap_body($inbox, $mail, FT_PEEK); 
    } else {
        //    
    }
   echo $output;
   $output = '';
}

// colse the connection
imap_expunge($inbox);
imap_close($inbox);

要使用它，您需要安裝並啟用php5-imap

您可以使用以下命令安裝 PHP5 IMAP 模塊：

apt-get install php5-imap

但是默認情況下它沒有啟用所以啟用它：

php5enmod imap

要查看更改，請重新啟動 Apache

service apache2 restart

對於帶有 Xampp7 及更高版本的 Windows，

轉到php.ini ，去掉分號，

;extension=imap
