在php中獲取X-Mailer屬性imap

Question

如何在php imap lib中獲得X-Mailer屬性？

我找不到任何屬性取功能http://php.net/manual/en/function.imap-fetchheader.php

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

    $header = imap_fetchheader($inbox, 1); 
    var_dump($header); 


/* close the connection */ 
imap_close($inbox); 

輸出我得到的是

string(405) "MIME-Version: 1.0

方法：

• 獲取與imap_fetchheader頭（）
從集流管10
• 提取物X-梅勒場從場
• 提取值

實施例：

$inbox = imap_open($hostname,$username,$password); 
if (!$inbox) { 
    echo('Cannot connect to Gmail: ' . imap_last_error()); 
    exit; 
} 
$header_string = imap_fetchheader($inbox, 1); 
preg_match_all('/([^: ]+): (.+?(?:\r\n\s(?:.+?))*)\r\n/m', 
     $header_string, $matches); 
$headers = array_combine($matches[1], $matches[2]); 
$xmailer = $headers['X-Mailer']; 
imap_close($inbox);
