篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了怎么利用php发送邮件求详细教程相关的知识，希望对你有一定的参考价值。

参考技术A php虽然提供了mail()函数，但并不好用，而PHPMailer是一个不错的邮件发送工具，接下来将详细介绍，需要了解的朋友可以参考下：

本人使用wamp集成开发环境，Apache2.4.4, mysql5.6.12 , php5.4.12.开始的时候使用mail()发送邮件，更改配置始终无法成功，了解到mail()函数使用需要sendmail程序。又下载了sendmail程序扩展包。按照网上的说法也改好了php.ini和sendmail.ini。使用foxmail 7.1创建了自己的qq邮箱账户，开启了POP3/SMTP服务，更改发件服务器为POP3，使用和收件服务器相同的身份验证，结果还是报错：Warning: mail(): SMTP server response: 503 Error: need EHLO and AUTH first ! in F:\PHP\wamp\www\mail.php on line 8。以下是使用mail()函数发送邮件的php代码：

[php] view plain copy
<span style="font-size:14px"><?php

$to = "757006080@qq.com";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "757006080@qq.com";
$headers = "From: $from";
$send=mail($to,$subject,$message,$headers);
if($send)
echo "Mail Sent";
else
echo "Sorry,mail sent failed!"

?></span>
在CSDN论坛上发现phpmailer可以方便快捷的发送邮件，以下写出详细使用教程：
1.需要下载PHPMailer文件包，(点击打开链接)

2.确认你的服务器已经系统支持socket,通过phpinfo()查看是否支持socket；

3.把文件解压到你的WEB服务器目录下，就可以使用PHPMailer发送邮件了。

以下为前台表单php代码：

[php] view plain copy
<span style="font-size:14px"><html>
<body>
<h3>phpmailer Unit Test</h3>
请你输入<font color="#FF6666">收信</font>的邮箱地址:
<form name="phpmailer" action="testemail.php" method="post">
<input type="hidden" name="submitted" value="1"/>
邮箱地址: <input type="text" size="50" name="to" />
<br/>
<input type="submit" value="发送"/>
</form>
</body>
</html> </span>
以下为后台程序：

[php] view plain copy
<?php
/**
* Simple example script using PHPMailer with exceptions enabled
* @package phpmailer
* @version $Id$
*/

header("content-type:text/html;charset=utf-8");

ini_set("magic_quotes_runtime",0);

require('class.phpmailer.php');

try
$mail = new PHPMailer(true); //New instance, with exceptions enabled

//$body = file_get_contents('contents.html');
//$body = preg_replace('/\\\\/','', $body); //Strip backslashes
$to = $_POST['to'];
$mail->CharSet="GB2312";//设置邮件字符编码否则邮件会乱码
$mail->Encoding="base64";
$mail->IsSMTP(); // tell the class to use SMTP
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Port = 25; // set the SMTP server port
$mail->Host = "smtp.qq.com"; // SMTP server
$mail->Username = "757006080@qq.com"; // SMTP server username
$mail->Password = "000000000000"; // SMTP server password

//$mail->IsSendmail(); // tell the class to use Sendmail

$mail->AddReplyTo("757006080@qq.com","han qing");

$mail->From = "757006080@qq.com";
$mail->FromName = "han qing";

//$to = "hanqing757@gmail.com";

$mail->AddAddress($to);

$mail->Subject =$mail->Subject = "=?utf-8?B?" . base64_encode("First PHPMailer Message") . "?=";

$mail->Body = "<h1>phpmailer演示</h1> 这是用PHPMAILER发的第一份邮件,从QQ邮箱发到Google邮箱.";

$mail->AddAttachment("F:/myloe.jpg");

$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->WordWrap = 80; // set word wrap

//$mail->MsgHTML($body);

$mail->IsHTML(true); // send as HTML

$mail->Send();
echo 'Message has been sent.';
catch (phpmailerException $e)
echo $e->errorMessage();

?> 参考技术B 这个还是百度吧，很简单的东西。我写过java版的。追问

你会php的么？

追答

不会，你搜到改改就行了。就是些基础的写法，没什么的.

参考技术C 亲测管用，参考下面的地址

夹缝中求生存-在一无所有的php虚拟主机环境下利用smtp发送邮件

夹缝中求生存

利用php虚拟主机向指定QQ邮箱账户发送一份电子邮件，以163邮箱为例。

前言：在阿里云虚拟主机php的苛刻环境下，php函数库少的可怜，各种不支持，想要发送一份不被收件邮箱屏蔽的邮件，顿时感觉整个世界都黑暗了，不过还好，在夹缝中求生存，踩过了各种坑，最后还是有解决之道的。

首先得注册163个人邮箱账号，配置SMTP并设置授权密码（此部分不再赘述，如有疑问请自行百度）。
几点提醒：
- 邮件发送成功却未收到邮件提醒：发送的邮件可能被放到了垃圾箱，尤其是注意账户为QQ邮箱的收件人。
- 邮件内容不要太多，否则很有可能会被当成垃圾邮件处理（亲测发送整段html代码邮件会被QQ收件邮箱会屏蔽拒收邮件，而163收件邮箱会正常接收邮件），尤其是注意账户为QQ邮箱的收件人。
- 以下是以163邮箱配置smpt，亲测代码可用，其他邮箱配置smpt未作尝试。
- 已解决自定义发件人，代码中已写明。
- 已解决当收件邮箱为QQ邮箱时，邮件会被QQ邮箱当作垃圾邮件处理的问题。
以下是php代码：

test.php

 1 <?php
 2 header("Content-Type: text/html; charset=utf-8");
 3 
 4 //引入发送邮件类
 5 require("smtp.php");
 6 //使用163邮箱服务器
 7 $smtpserver = "smtp.163.com";
 8 //163邮箱服务器端口
 9 $smtpserverport = 25;
10 //你的163服务器邮箱账号
11 $smtpusermail = "****@163.com";//
12 //收件人邮箱，***@163.com/***@qq.com
13 $smtpemailto = "[email protected]";
14 //发送人，可随意显示发件人
15 $sender = "邮件发送方";
16 //你的邮箱账号(去掉@163.com)
17 $smtpuser = "****";//你的163邮箱去掉后面的163.com
18 //你的邮箱密码
19 $smtppass = "*****"; //你的163邮箱SMTP的授权码，千万不要填密码！！！
20 
21 //邮件主题
22 $mailsubject = "邮件提醒";
23 //邮件内容
24 $mailbody = "
25 详细信息：</br>
26 <h1>这是一封测试邮件</h1>
27 ";
28 //邮件格式（HTML/TXT）,TXT为文本邮件
29 $mailtype = "HTML";
30 //这里面的一个true是表示使用身份验证,否则不使用身份验证.
31 $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);
32 //是否显示发送的调试信息
33 $smtp->debug = TRUE;
34 //发送邮件
35 $smtp->sendmail($smtpemailto, $smtpusermail, $sender ,$mailsubject, $mailbody, $mailtype);
