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);

?>
