Detailed explanation of examples of receiving emails using IMAP with PHP

This article mainly introduces the method of receiving emails based on PHP based on IMAP. It analyzes the related settings and usage skills of PHP based on IMAP receiving emails based on examples. It also comes with descriptions of IMAP related functions. Friends who need it can refer to it. I hope it can help. Everyone

needs to deal with the problem of bounced emails in the company's corporate mailbox: the initial idea is to capture the emails through simulated login. (This kind of thing has been done to me many times, and I am familiar with it. ), but the mailbox is still a bit complicated.

Later I remembered that smtp is used to send emails when sending emails. Remember that you can also receive emails. Use Tencent Enterprise Mailbox Helphttp://service.exmail. qq.com/cgi-bin/help?subtype=1&&id=28&&no=1000584

I saw that both IMAP and POP can receive emails, and then I found that PHP has a built-in IMOP function, so I wrote an example:

//以腾讯企业邮箱做了测试
$mailServer="imap.exmail.qq.com"; //IMAP主机
$mailLink="{{$mailServer}:143}INBOX" ; //imagp连接地址：不同主机地址不同
$mailUser = '***'; //邮箱用户名
$mailPass = '***'; //邮箱密码
$mbox = imap_open($mailLink,$mailUser,$mailPass); //开启信箱imap_open
$totalrows = imap_num_msg($mbox); //取得信件数
for ($i=1;$i<$totalrows;$i++){
  $headers = imap_fetchheader($mbox, $i); //获取信件标头
  $headArr = matchMailHead($headers); //匹配信件标头
  $mailBody = imap_fetchbody($mbox, $i, 1); //获取信件正文
}
/**
 *
 * 匹配提取信件头部信息
 * @param String $str
 */
function matchMailHead($str){
  $headList = array();
  $headArr = array(
    &#39;from&#39;,
    &#39;to&#39;,
    &#39;date&#39;,
    &#39;subject&#39;
  );
  foreach ($headArr as $key){
    if(preg_match(&#39;/&#39;.$key.&#39;:(.*?)[\n\r]/is&#39;, $str,$m)){
      $match = trim($m[1]);
      $headList[$key] = $key==&#39;date&#39;?date(&#39;Y-m-d H:i:s&#39;,strtotime($match)):$match;
    }
  }
  return $headList;
}
