一、使用PHP内置的mail()函数
二、使用封装SMTP协议的邮件类
具体可以参考这篇文章，希望对你有帮助
如何使用php中的mail函数发送html格式的信采用 phpmailer类，来做邮件发送，是很多PHP程序所采用的一个类发送
require(ROOT.'/class/phpMailer.class.php');//邮件发送类
/**
* 发送邮件
* @param string $to 接收人邮件地址
* @param string $title 邮件标题
* @param string $contents 邮件内容 支持HTML格式
* @param string $type 判断是否要加附件
* @param string $accessory 附件的名字
* @return 成功返回true,失败返回错误信息
*/
function sendEmail($to,$title,$contents,$type = '',$accessory =''){
$mail = new PhpMailer(true);
$mail->IsSMTP();
$mail->CharSet ="UTF-8";//编码
$mail->Debugoutput = 'html';// 支持HTML格式
$mail->Host = T_SMTP_SERVER;//HOST 地址
$mail->Port = 25;//端口
$mail->SMTPAuth = true;
$mail->Username = T_SMTP_LOGIN;//用户名
$mail->Password = T_SMTP_PASSWORD;//密码
$mail->SetFrom(T_SMTP_FROM,T_SMTP_FROM_NAME);//发件人地址, 发件人名称
$mail->AddAddress($to);//收信人地址
//$mail->Subject = "=?utf-8?B?" . base64_encode() . "?=";
if (!empty($type)) {
$mail->AddAttachment($type,$accessory); // 添加附件,并指定名称
}
$mail->Subject = $title;//邮件标题
$mail->MsgHTML($contents);
if ($mail->Send()){
return true;
}else{
return $mail->errorMessage();
}
}
如何使用php的mail函数发送邮件如果需要用php的mail()函数来发送邮件，是需要服务器安装sendmail组件才能支持的，这个在php的手册中mail()函数部分也有介绍到。在Ubuntu下安装sendmail的命令：sudo apt-get install sendmail安装好之后，启动sendmail服务：sudo service sendmail start有了sendmail的支持，就可以在php中用mail()函数发送邮件了。
PHP如何使用MAIL函数发邮件PHP mail 发送邮件
(PHP 4, PHP 5)
mail — 发送邮件
说明
bool mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )
发送一封电子邮件。
参数
to
电子邮件收件人，或收件人列表。
本字符串的格式必须符合 » RFC 2822。例如：
user@example.com
user@example.com, anotheruser@example.com
User <user@example.com>
User <user@example.com>, Another User <anotheruser@example.com>
subject
电子邮件的主题。
Caution
本项不能包含任何换行符，否则邮件可能无法正确发送。
message
所要发送的消息。
行之间必须以一个 LF（ ）分隔。每行不能超过 70 个字符。
Caution
（Windows 下）当 PHP 直接连接到 SMTP 服务器时，如果在一行开头发现一个句号，则会被删掉。要避免此问题，将单个句号替换成两个句号。 <?php
$text = str_replace(" .", " ..", $text);
?>
additional_headers（可选项）
String to be inserted at the end of the email header.
This is typically used to add extra headers (From, Cc, and Bcc). Multiple extra headers should be separated with a CRLF ( ).
如何使用php的mail函数可以，但是这要需要smtp.163.com的用户名与密码
我给你一个邮件发送类，你可以直接用
/*
名称：smtpsend.class.php
功能:邮件发送类,实现邮件发送功能 ,可以发送html邮件；可验证用户是否具有发送权限；可实现从任意服务器邮箱发送邮件，并非局限于本机。

PHP mail()的问题你的PHP是在WINDOWS上运行吧，那么需要在PHP.INI文件里面检查下面行的内容：
[mail function]
SMTP = localhost
smtp_port = 25
;sendmail_from = me@example.com
前面两行设置SMTP的服务器地址和端口，最后一行设置默认的发件人地址（不是必需设置的）。
发信的mail函数格式如下：
bool mail ( string to, string subject, string message [, string additional_headers [, string additional_parameters]] )
前面三个参数是对方地址、邮件标题、正文，例如：
<?php
// The message
$message = "Line 1\nLine 2\nLine 3";
// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap($message, 70);
// Send
mail('caffinated@example.com', 'My Subject', $message);
?>
后面的参数可以用来进行设置邮件的头部信息，例如指定发件人地址，例如：
<?php
$to = 'nobody@example.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: webmaster@example.com' . "\r\n" .
'Reply-To: webmaster@example.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
?>
