php 发送邮件，支持文本信息和附件

系统需要安装 sendmail,并启动 sendmail 服务

开启httpd发送邮件支持:

setsebool -P httpd_can_sendmail 1

代码如下：

&lt;?php

使用方法如下：

第1种情况，只发送消息

&lt;?php 
require_once('email.class.php');

//发件人
$from = 'support@aqwu.net';
//收件人
$to = 'zhangxj@aqwu.net';
//主題
$subject = "test1";


$message = "这是一条中文信息，this is a english message.";

$mailMsg = new CMailMessage($from,$to,$subject,$message);
$mailMsg-&gt;sendMessage();

?&gt;

<?php

require_once('email.class.php');

//发件人

$from = 'support@aqwu.net';

//收件人

$to = 'zhangxj@aqwu.net';

//主題

$subject = "test1";

$message = "这是一条中文信息，this is a english message.";

$mailMsg = new CMailMessage($from,$to,$subject,$message);

$mailMsg->sendMessage();

第2种情况，发送消息和文件，文件以附件形式来发送

&lt;?php 
require_once('email.class.php');

//发件人
$from = 'support@aqwu.net';
//收件人
$to = 'zhangxj@aqwu.net';
//主題
$subject = "test2";


$message = "这是一条中文信息，this is a english message.";
$sourcefile = 'test.exe';
$downfilename = "test.exe";
$mimetype = "application/octet-stream";

$mailMsg = new CMailMessage($from,$to,$subject,$message);
$mailMsg-&gt;attach_file($sourcefile,$downfilename,$mimetype);
$mailMsg-&gt;sendMessage();

?&gt;

<?php

require_once('email.class.php');

//发件人

$from = 'support@aqwu.net';

//收件人

$to = 'zhangxj@aqwu.net';

//主題

$subject = "test2";

$message = "这是一条中文信息，this is a english message.";

$sourcefile = 'test.exe';

$downfilename = "test.exe";

$mimetype = "application/octet-stream";

$mailMsg = new CMailMessage($from,$to,$subject,$message);

$mailMsg->attach_file($sourcefile,$downfilename,$mimetype);

$mailMsg->sendMessage();

第3种情况，发送消息和内容，内容以附件形式来发送

&lt;?php 
require_once('email.class.php');

//发件人
$from = 'support@aqwu.net';
//收件人
$to = 'zhangxj@aqwu.net';
//主題
$subject = "test3";


$message = "这是一条中文信息，this is a english message.";
$contents = 'this is a test file info';
$downfilename = "test.txt";
$mimetype = "application/octet-stream";

$mailMsg = new CMailMessage($from,$to,$subject,$message);
$mailMsg-&gt;attach_content($contents,$downfilename,$mimetype);
$mailMsg-&gt;sendMessage();

?&gt;

<?php

require_once('email.class.php');

//发件人

$from = 'support@aqwu.net';

//收件人

$to = 'zhangxj@aqwu.net';

//主題

$subject = "test3";

$message = "这是一条中文信息，this is a english message.";

$contents = 'this is a test file info';

$downfilename = "test.txt";

$mimetype = "application/octet-stream";

$mailMsg = new CMailMessage($from,$to,$subject,$message);

$mailMsg->attach_content($contents,$downfilename,$mimetype);

$mailMsg->sendMessage();

第4种情况，发送消息和多个文件和多个内容，文件和内容均以附件形式来发送

&lt;?php 
require_once('email.class.php');

//发件人
$from = 'support@aqwu.net';
//收件人
$to = 'zhangxj@aqwu.net';
//主題
$subject = "test4";


$message = "这是一条中文信息，this is a english message.";
$contents = 'this is a test file info';
$downfilename = "test.txt";
$mimetype = "application/octet-stream";

$mailMsg = new CMailMessage($from,$to,$subject,$message);
$mailMsg-&gt;attach_content($contents,$downfilename,$mimetype);

$sourcefile = 'test.exe';
$downfilename = "test.exe";
$mimetype = "application/octet-stream";
$mailMsg-&gt;attach_file($sourcefile,$downfilename,$mimetype);

$mailMsg-&gt;sendMessage();

?&gt;

<?php

require_once('email.class.php');

//发件人

$from = 'support@aqwu.net';

//收件人

$to = 'zhangxj@aqwu.net';

//主題

$subject = "test4";

$message = "这是一条中文信息，this is a english message.";

$contents = 'this is a test file info';

$downfilename = "test.txt";

$mimetype = "application/octet-stream";

$mailMsg = new CMailMessage($from,$to,$subject,$message);

$mailMsg->attach_content($contents,$downfilename,$mimetype);

$sourcefile = 'test.exe';

$downfilename = "test.exe";

$mimetype = "application/octet-stream";

$mailMsg->attach_file($sourcefile,$downfilename,$mimetype);

$mailMsg->sendMessage();
