PHP邮件发送类，添加发送附件

支持发送纯文本邮件和HTML格式的邮件，可以多收件人，多抄送，多秘密抄送，带附件的邮件。 欢迎提出意见。 发送带附件的邮件，每次会多出一个0B的txt文件，不知道为什么！ 上一篇地址：http://www.oschina.net/code/snippet_1182150_25162 这里提供两端代码，

发送带附件的邮件，每次会多出一个0B的txt文件，不知道为什么！

上一篇地址：http://www.oschina.net/code/snippet_1182150_25162

这里提供两端代码，第一段功能全，第二部分的只是可以发送纯文本和HTMl邮件，一般发送系统通知的邮件这种就够了！ PHP

* 需要的php扩展，sockets和Fileinfo。
* @example
* $mail = new MySendMail();
* $mail->setServer("XXXXX", "XXXXX@XXXXX", "XXXXX"); 设置smtp服务器
* $mail->setFrom("XXXXX"); 设置发件人
* $mail->setReceiver("XXXXX"); 设置收件人，多个收件人，调用多次
* $mail->setCc("XXXX"); 设置抄送，多个抄送，调用多次
* $mail->setBcc("XXXXX"); 设置秘密抄送，多个秘密抄送，调用多次
* $mail->setMailInfo("test", "<b>test</b>"); 设置邮件主题、内容
* $mail->sendMail(); 发送
