PHP学习：PHP基于IMAP收取邮件的方法示例

//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();
  $headArr = array(
    'from',
    'to',
    'date',
    'subject'
  );
  foreach ($headArr as $key){
    if(preg_match('/'.$key.':(.*?)[\n\r]/is', $str,$m)){
      $match = trim($m[1]);
      $headList[$key] = $key=='date'?date('Y-m-d H:i:s',strtotime($match)):$match;
    }
  }
  return $headList;
}
