PHP发送电子邮件

1、导入文件，如本案例把Stmp.class.php放到Common\Common目录下，代码很多，直接复制就行!

2、设置配置文件 Commom\Conf 目录下的 config.php

 // 配置邮件发送服务器
         'THINK_EMAIL' => array(
                              'SMTP_HOST'   => 'smtp.163.com', //SMTP服务器
                              'SMTP_PORT'   => '25', //SMTP服务器端口
                              'SMTP_USER'   => '*******@163.com', //SMTP服务器用户名,你的邮箱名
                              'SMTP_PASS'   => '*******', //SMTP服务器密码，邮箱密码
                              'FROM_EMAIL'  => '********@163.com', //发件人EMAIL
                              'FROM_NAME'   => '********', //发件人名称
                              'REPLY_EMAIL' => '', //回复EMAIL（留空则为发件人EMAIL）
                              'REPLY_NAME'  => '', //回复名称（留空则为发件人名称）
         ),

3、具体使用

/*
     * 【执行发送邮箱验证码】
     *
     * @access private
     * @param string $smtpemailto     收件人邮箱
     * @param string $mailsubject     邮件主题
     * @param string $mailbody        邮件内容
     * @param string $mailtype         邮件格式
     * @return boolean
     *
     **/
    private function executeSendEmailCode($smtpemailto, $mailsubject, $mailbody, $mailtype = "HTML"){
        $config_mail = C('THINK_EMAIL');//获取配置信息
        $smtpserver     =     $config_mail['SMTP_HOST'];//SMTP服务器
        $smtpserverport =    $config_mail['SMTP_PORT'];//SMTP服务器端口
        $smtpusermail     =     $config_mail['FROM_EMAIL'];//SMTP服务器的用户邮箱
        $smtpuser         =     $config_mail['SMTP_USER'];//SMTP服务器的用户帐号
        $smtppass         =     $config_mail['SMTP_PASS'];//SMTP服务器的用户密码

        $mailtime        =    date("Y-m-d H:i:s");

        $utfmailbody    =    iconv("UTF-8","GB2312",$mailbody);//转换邮件编码
//         $mailtype         =     "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件

        $smtp = new Smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//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->debug = FALSE;//是否显示发送的调试信息 FALSE or TRUE

        $ret = $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $utfmailbody, $mailtype);

        return  $ret;
    }
