php發送email

1. 用php發送電子郵件的方法

<?

class smail {
//您的SMTP 伺服器供應商，可以是域名或IP地址
var $smtp = "";
//SMTP需要要身份驗證設值為 1 不需要身份驗證值為 0，現在大多數的SMTP服務商都要驗證，如不清楚請與你的smtp 服務商聯系。
var $check = 1;
//您的email帳號名稱
var $username = "";
//您的email密碼
var $password = "";
//此email 必需是發信伺服器上的email
var $s_from = "";

/*
* 功能：發信初始化設置
* $from 你的發信伺服器上的郵箱
* $password 你的郵箱密碼
* $smtp 您的SMTP 伺服器供應商，可以是域名或IP地址

$this->username = substr( $from, 0, strpos( $from , "@" ) );
$this->password = $password;
$this->smtp = $smtp ? $smtp : $this->smtp;
$this->check = $check;
$this->s_from = $from;
}
}

/*

if (!$fp ) return "聯接伺服器失敗".__LINE__;
set_socket_blocking($fp, true );

$lastmessage=fgets($fp,512);
if ( substr($lastmessage,0,3) != 220 ) return "錯誤信息1:$lastmessage".__LINE__;

//HELO
$yourname = "YOURNAME";
if($this->check == "1") $lastact="EHLO ".$yourname."\r\n";

}
}
/*發送示例
$sm = new smail( "用戶名@163.com", "密碼", "smtp.163.com" );
$end = $sm->send( "目標郵箱", "來源郵箱", "這是標題", "這是郵件內容" );
if( $end ) echo $end;
else echo "發送成功！";

2. PHP怎樣才能非同步發送郵件

<?php
$domain="domain";
$url="/system_mail.php";
$par="email=".implode(',',$emailarr)."&........";
$header="POST$urlHTTP/1.0
";
$header.="Content-Type:application/x-www-form-urlencoded
";
$header.="Content-Length:".strlen($par)."

";
$fp=@fsockopen($domain,80,$errno,$errstr,30);
fputs($fp,$header.$par);
fclose($fp);

echo''發送完畢';
?>

3. PHP到底怎麼發送郵件啊，PHP高手請指教!

很懷疑樓上的是不是都是抄的。宴鏈

以下是我幫別人寫的一段發送找回密碼的代碼，在windows,apache2,php5下正常運行，也沒有亂碼現象

需要windows的STMP支持，
STMP可以在控制面板的 添加/刪除軟體 裡面安裝

$to = $info['txtEmail'];
$subject = "找回密碼";
$subject = "=?UTF-8?B?".base64_encode('找回密碼')."?=";
$message = $txtUnionID.'，你好：
請點擊下面鏈接找回密碼：
<a href="http://'.$_SERVER['SERVER_NAME']" target="_blank">
http://'.$_SERVER['SERVER_NAME'].'/union/index.php?m=forgetPassword&id='.$md5.'</a>
(如果鏈接無法點擊，
請將它拷貝到瀏覽器的地址欄中。)
有效時間為三天
此郵件為系統自動發送慶祥跡，請勿回復'.
$_SERVER['SERVER_NAME'].
date('Y年m月d日');
$from = "webmaster@nbjoy.net";
//$headers = "From: $from";
$headers = 'MIME-Version: 1.0' . "譽並\r\n";
$headers .= "From: $from"."\r\n"."Reply-to:$from"."\r\n"."X-Mailer: PHP".phpversion()."\r\n";
$headers .= "Content-type: text/html; charset=utf-8\r\n";
$headers .= "Content-Transfer-Encoding: 8bit\r\n";
mail($to,$subject,$message,$headers);
