复制代码 代码示例:

<?php
/**
* php socket smtp发送邮件
* edit: www.jbxue.com
*/

//define("SOL", "\n");
define("EOL", "\r\n");
define("SMTP_HOST", "smtp.163.com");//SMTP服务器
define("SMTP_PORT", "25");//SMTP服务器端口
define("SMTP_USER", "");//SMTP服务器的用户帐号
define("SMTP_PASS", "");//SMTP服务器的用户密码

$from = "";//SMTP服务器的用户邮箱
$to = "";//发送给谁 可用逗号隔开多个邮箱
$cc = "";
$bcc = "";

$subject="这是一个由PHP发送的带附件的邮件";//邮件主题 很多客户端会有乱码,所以转一下码
$body = "这个是一个带附件的邮件发送程序<hr>看到没,这里显示了HTM标签哦;<a href='http://www.jbxue.com/'>请点开链接</a><input type='button' id='aaa' name=\"aaa\"> ".date('Y-m-d H:i:s');//邮件内容
$smtp = new smtp(SMTP_HOST,SMTP_PORT,SMTP_USER,SMTP_PASS, true);//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.
