好久冒寫點東西了.....最近生活壓抑的很....為生活而勞累，整理下郵件發送的執行個體了，網上也有很多，我這個也是提取整理好的，測試Ok，首頁郵件類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.‘發送不成功‘;
}

return 1;
}
}

function send_win32_mail($to,$subject,$message,$from,$from_name,$host,$port,$mailformat=1)
{
ini_set(‘SMTP‘, $host);
ini_set(‘smtp_port‘, $port);
ini_set(‘sendmail_from‘, $from);

$headers = ‘From: ‘.$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";

foreach(explode(‘,‘, $to) as $touser)
{
$touser = trim($touser);
if($touser)
{
[email protected]($touser, $subject, $message, $headers);
if(!$mail_return)
{
return $touser.‘發送不成功‘;
}
}
}
return 1;
}

//通過sock發送e_mail，不支援附件，
//-------------------------------------------------------------------------------------------------------
function email_sock($host,$port,$errno,$errstr,$timeout,$auth,$user,$pass,$from)//建構函式
{
$this->host = $host;
$this->port = $port;
$this->errno = $errno;
$this->errstr = $errstr;
$this->timeout = $timeout;
$this->auth = $auth;
$this->user = $user;
$this->pass = $pass;
$this->from = $from;
}

function send_mail_sock($subject,$message,$to,$from_name,$mailformat=0)//郵件標題,郵件內容,收件地址,郵件格式1=text|0=html,預設為0
{
$host = $this->host;
$port = $this->port;

$from = $this->from;

/*
1.建立sock，並開啟串連
2.設定為阻塞模式
3.測試smtp應答碼是否為220，220代表郵件服務就緒
4.發送使用者身分識別驗證，由使用者佈建
1=EHLO Host Domain \r\n
0=HELO Host Domain \r\n
?.讀取伺服器端發送給用戶端的返回資料
smtp.163.com 發送的資料為：
250-PIPELINING//流水命令，告訴用戶端可以一次發送多個命令來提高速度，在這裡PHP
並沒有使用，因為PHP單個檔案的運行還是單線程的
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250 8BITMIME//得到這一行也就是smtp伺服器發送結束了，等待用戶端發送命令
5.發送AUTH LOGIN命令
6.發送使用者名稱
7.發送密碼
?.身分識別驗證過成功後後，
8.向伺服器添加from
9.向伺服器添加to
10.發送DATA命令,開始輸入email資料,以"."號結束
11.書寫郵件內容
12.將郵件內容發送到smtp伺服器
13.發送QUIT命令，結束會話

使用方法，建立send.php,源碼如下
<?php
//*
include(‘smtp_email_class.php‘);
//定義參數------------------------------------------------------
$host = ‘smtp.163.com‘;//smtp伺服器位址，我這裡又能夠的是163的，視情況而定
$from = ‘[email protected]‘;//自己的郵件地址
$port = 25;//連接埠
$errno = 0;//錯誤返回號
$errstr = ‘‘;//錯誤返回內容
$timeout = 10;//系統運行逾時
$auth = 1;//是否需要 AUTH LOGIN 驗證, 1=是, 0=否
$user = ‘你的郵件使用者名‘;//smtp伺服器使用者名稱
$pass = ‘你的郵件密碼‘;//smtp伺服器密碼
$from_name=‘你的大名‘;//連絡人名稱
//---------------------------------------------------------------
$send_mode=2;
$em=new email();//使用類
if($send_mode==1){
//使用PHP自己支援的mail函數發送郵件，發送郵件需要smtp服務支援
if($em->send_mail(‘發送給某人（張三）的郵件地址‘,‘標題‘,"內容",‘[email protected]‘,‘自己的名稱/連絡人名稱‘,0)){
echo("郵件發送成功....");
}
}elseif($send_mode==2){
$em->email_sock($host,$port,$errno,$errstr,$timeout,$auth,$user,$pass,$from);
if($em->send_mail_sock(‘標題‘,‘歡迎和諧‘,‘發送給某人（張三）的郵件地址‘,‘你的大名‘,0)){
//$em->send_mail_sock(‘標題‘,‘內容‘,‘[email protected]‘,‘連絡人名稱‘,0)
echo("郵件發送成功Ok....");
}
}

?>
