PHP处理postfix邮件内容的方法

本文实例讲述了PHP处理postfix邮件内容的方法。分享给大家供大家参考。具体如下：

    <?php
    //从输入读取到所有的邮件内容
    $email = "";
    $fd = fopen("php://stdin", "r");
    while (!feof($fd)) {
     $email .= fread($fd, 1024);
    }
    fclose($fd);
    //记录所有的内容，测试
    file_put_contents("/tmp/mail/".time(), $email);
    //处理邮件
    $lines = explode("\n", $email);
    // empty vars
    $from = "";
    $date = "";
    $subject = "";
    $message = "";
    $splittingheaders = true;
    for ($i=0; $i<count($lines); $i++) {
     if ($splittingheaders) {
      // look out for special headers
      if (preg_match("/^Subject: (.*)/", $lines[$i], $matches)) {
       $subject = $matches[1];
      }
      if (preg_match("/^From: (.*)/", $lines[$i], $matches)) {
       if(strpos($lines[$i],"<")){
        //the name exist too in from header
        $data = explode('<',$lines[$i]);
        $from = substr(trim($data[1]),0,-1);
       }else{
        //only the mail
        $from = $matches[1];
       }
      }
      if (preg_match("/^Date: (.*)/", $lines[$i], $matches)) {
       $date = $matches[1];
      }
     } else {
      // not a header, but message
      $message .= $lines[$i]."\n";
     }
     if (trim($lines[$i])=="") {
      // empty line, header section has ended
      $splittingheaders = false;
     }
    }
    $when = date("Y-m-d G:i:s");
    $data = explode('@',$from);
    $username = $data[0];
    //记录到数据库
    $sql = "insert into mails ( `username`, `from`, `subject`, `date`, `message`) values ( '$username', '$from', '$subject', '$when', '$message')";
    //测试
    file_put_contents("/tmp/mail2.log", $sql);
    ?>
