好久冒写点东西了.....最近生活压抑的很....为生活而劳累，整理下邮件发送的实例了，网上也有很多，我这个也是提取整理好的，测试Ok，首页邮件类smtp_email_class.php如下：
<?php
class email
{
function send_mail($to,$subject,$message,$from,$from_name,$mailformat=1)
{
if(function_exists(‘mail‘))
{
$headers = ‘From: ‘.$from_name.‘<‘.$from.‘>‘."\r\n";
$headers .= ‘TO: ‘.$to."\r\n";
if($mailformat)
{$headers .="Content-Type: text/html;\r\n";}
else
{$headers .="Content-Type: text/plain;\r\n";}
$headers .="charset=gb2312\r\n\r\n";
$message = str_replace("\r", ‘‘, $message);
[email protected]($to, str_replace("\n",‘ ‘,$subject), $message,$headers);
if(!$mail_return)
{
return $to.‘发送不成功‘;
}
return 1;
}
}
function send_win32_mail($to,$subject,$message,$from,$from_name,$host,$port,$mailformat=1)
{
ini_set(‘SMTP‘, $host);

else
{$headers .="Content-Type: text/plain;\r\n";}
$headers .="charset=gb2312\r\n\r\n";
foreach(explode(‘,‘, $to) as $touser)
{
$touser = trim($touser);
if($touser)
{
[email protected]($touser, $subject, $message, $headers);
if(!$mail_return)
{
return $touser.‘发送不成功‘;

return 1;

/*
1.创建sock，并打开连接
2.设置为阻塞模式
3.测试smtp应答码是否为220，220代表邮件服务就绪
4.发送用户身份验证，由用户设置
1=EHLO Host Domain \r\n
0=HELO Host Domain \r\n
?.读取服务器端发送给客户端的返回数据
smtp.163.com 发送的数据为：
250-PIPELINING//流水命令，告诉客户端可以一次发送多个命令来提高速度，在这里PHP
并没有使用，因为PHP单个文件的运行还是单线程的
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250 8BITMIME//得到这一行也就是smtp服务器发送结束了，等待客户端发送命令
5.发送AUTH LOGIN命令
6.发送用户名
7.发送密码
?.身份验证过成功后后，
8.向服务器添加from
9.向服务器添加to
10.发送DATA命令,开始输入email数据,以"."号结束
11.书写邮件内容
12.将邮件内容发送到smtp服务器
13.发送QUIT命令，结束会话

使用方法，新建send.php,源码如下
<?php
//*
include(‘smtp_email_class.php‘);
//定义参数------------------------------------------------------
$host = ‘smtp.163.com‘;//smtp服务器地址，我这里又能够的是163的，视情况而定
$from = ‘[email protected]‘;//自己的邮件地址
$port = 25;//端口
$errno = 0;//错误返回号
$errstr = ‘‘;//错误返回内容
$timeout = 10;//系统运行超时
$auth = 1;//是否需要 AUTH LOGIN 验证, 1=是, 0=否
$user = ‘你的邮件用户名‘;//smtp服务器用户名
$pass = ‘你的邮件密码‘;//smtp服务器密码
$from_name=‘你的大名‘;//联系人名称
//---------------------------------------------------------------
$send_mode=2;
$em=new email();//使用类
if($send_mode==1){
//使用PHP自己支持的mail函数发送邮件，发送邮件需要smtp服务支持
if($em->send_mail(‘发送给某人（张三）的邮件地址‘,‘标题‘,"内容",‘[email protected]‘,‘自己的名称/联系人名称‘,0)){
echo("邮件发送成功....");
}
}elseif($send_mode==2){
$em->email_sock($host,$port,$errno,$errstr,$timeout,$auth,$user,$pass,$from);
if($em->send_mail_sock(‘标题‘,‘欢迎和谐‘,‘发送给某人（张三）的邮件地址‘,‘你的大名‘,0)){
//$em->send_mail_sock(‘标题‘,‘内容‘,‘[email protected]‘,‘联系人名称‘,0)
echo("邮件发送成功Ok....");
}
}
?>
