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);
?>
