php发邮件代码

‘壹’ 如何通过一个php程序给不同的邮箱发送不同的邮件

1.需要一个用来发送电子邮件的文件的程序，也就是一个php文件，流行的phpmail有很多，今天以smtp.php为例演示。
2.将其复制到你的项目文件内，具体路径根据自己的实际情况，这里建了一个test文件，用来设置邮件参数，大家也可以自定义邮件参数文件。（PS：一般都是通过表单接受的）
3.smtp.php文件引入。
4.设置邮件参数，具体代码如下：
//引入发送邮件类
require("smtp.php");
$smtpserver = "smtp.163.com";
$smtpserverport = 25;
//你的163服务器邮箱账号
$smtpusermail = "@163.com";
//收件人邮箱
$smtpemailto = "@qq.com";
//你的邮箱账号(去掉@163.com)
$smtpuser = "";//SMTP服务器的用户帐号
//你的邮箱密码
$smtppass = ""; //SMTP服务器的用户密码
5.设置邮件内容，代码如下：
//邮件主题
$mailsubject = "测试邮件发送";
//邮件内容
$mailbody = "PHP+Mysql";
//邮件格式（HTML/TXT）,TXT为文本邮件
$mailtype = "TXT";
//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.
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);
//是否显示发送的调试信息
$smtp->debug = TRUE;
//发送邮件
$smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
刷新页面后邮件发送，参数不出错的话1分钟左右即可发送成功。
至于发几个人，如何发自己定义下就行

‘肆’ php发送邮件的问题：php怎么才能发送邮件呢使用自带的函数，应该怎样设置相应的邮件服务器

首先，我不想给phpmailer这个东西做广告，但是我确实使用的这个东西，很费解。

1. 下载一个phpmailer类，里面主要的是三个文件class.phpmailer.phpclass.pop3.phpclass.smtp.php

2. 将这三个文件放到同一个文件夹.eg:papmailer

3. 申请一个网络邮件服务器(我用的是163服务器)

4. 编写发送邮件代码如下
   

5. /**
   *发送邮件
   *@paramunknown_type$sendto_email接收人Email
   *@paramunknown_type$subject邮件主题
   *@paramunknown_type$body邮件内容
   *@paramunknown_type$user_name接受人姓名
   */
   functionsend_email($sendto_email,$subject,$body,$user_name){
   require_once"phpmailer/class.phpmailer.php";
   $mail=newPHPMailer();//创建类对象
   $mail->IsSMTP();
   $mail->Host="smtp.163.com";//SMTPservers使用163服务器，邮件smtp服务器
   $mail->SMTPAuth=true;//turnonSMTPauthentication
   $mail->Username="你申请的163邮箱帐号";//SMTPusername注意：普通邮件认证不需要加@域名
   $mail->Password="163邮箱密码";//SMTPpassword
   $mail->From="发件人邮箱，可以使用上面163邮箱";//发件人邮箱
   $mail->FromName="发件人名称，自己随意命名";//发件人
   
   $mail->CharSet="utf8";//这里指定字符集！
   $mail->Encoding="base64";
   $mail->AddAddress($sendto_email,$user_name);//收件人邮箱和姓名
   $mail->IsHTML(true);//sendasHTML
   //邮件主题
   $mail->Subject=$subject;
   //邮件内容
   $mail->Body=$body;
   
   $mail->AltBody="text/html";
   if(!$mail->Send()){
   return$mail->ErrorInfo;
   }else{
   returntrue;
   }
   }

‘伍’ PHP中发送邮件的代码!

从代码来看，想必楼主是想把表单提交的内容发送至指定邮箱，而这个邮箱地址也是在表单中填写的，$sendTo变量的值被赋为表单项“toMail”传过来的值。
如此，你可以在填写表单的时候在toMail表单项里填入“[email protected]”，或者直接$sendTo="[email protected]"。

接下来就要考虑是否能发送出去了：

1、如果楼主配置的服务器安装了sendmail组件，就可以直接使用你写的这段代码来完成任务。

2、如果没有安装sendmail组件，就要接用smtp服务器来发送了。这样相对较复杂，要引用一个PHP类。具体代码如下：

SMTP.PHP：

‘陆’ 怎么利用php发送邮件求详细教程

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
<span style="font-size:14px"><?php

$to = "[email protected]";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "[email protected]";
$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
<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
<?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 = "[email protected]"; // SMTP server username
$mail->Password = "000000000000"; // SMTP server password

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

$mail->AddReplyTo("[email protected]","han qing");

$mail->From = "[email protected]";
$mail->FromName = "han qing";

//$to = "[email protected]";

$mail->AddAddress($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();
}
?>

‘柒’ PHP邮件发送

可以的，PHP直接连接SMTP服务器，进行登录和发送邮件。不过不可能简单哦，相当于编写一个OUTLOOK的功能，不可能很简单，可以参见这篇文章：http://www.chinaz.com/Program/PHP/041050242007.html

‘捌’ 求php 发送邮件的代码

php里面有mail函数用于发送邮件，具体你可以查一下手册，如果遇到问题再回来问。
以前来网络提问，很奇怪为什么老是有人去搜索一些网页文章来帖给我，这几天有闲心作答，才很诧异地发现，原来真的有很多人提了问题出来，等人去搜索答案回来贴。
这是你和你们同学约好的刷分办法吗？

这个类文件对邮件发送操作进行了封装，使用时不需要做任何更改。只需要在需要发送邮件的程序中包含即可。下面是一个使用的例子：

example.php
代码如下:

<?php
/******************************************
* PhpMailer类使用方法演示程序
******************************************/
require_once('PhpMailer.php');
$test =new PhpMailer("smtp.xxx.com","[email protected]","yourpassword");
$send =$test->send("[email protected]","一起PHP","邮件标题","邮件内容(支持HTML)");

if($send){
echo "发送成功。";
}else{
echo "发送失败。错误信息：".$test->errMsg;
}
?>

注释:

$test = new PhpMailer(参数1,参数2,参数3)

创建类对象。三个参数为必填。分别表示 SMTP服务器地址、用户名、密码（用户名为完整的邮件地址格式）。
如使用163的SMTP： smtp.163.split.netease.com 用户名[email protected] 密码 123456。

$send = $test->send(参数1,参数2,参数3,参数4)

调用 send()方法发送邮件，四个参数为必填。分别表示收信人地址、发信人姓名、邮件标题、邮件正文。
$send接收返回结果。发送成功返回true，失败返回false。并将失败原因存放在errMsg变量中。
