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

/**
* 邮件发送类
* 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
* 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
