导读：这篇文章主要介绍了PHP实现发送邮件的方法,基于简单邮件发送类实现该功能.给出了简单邮件发送类,并说明了具体使用方法,需要的朋友可以参考下

本文实例讲述了PHP实现发送邮件的方法。分享给大家供大家参考，具体如下：

邮件发送类

调用邮件发送类发送邮件

debug = TRUE;//是否显示发送的调试信息 if ($smtp->sendmail ( $flag,$smtpemailto,$smtpmailfrom,$mailsubject,$mailbody,$cc,$bcc,$additional_headers )) { echo ("发送成功"); } else { echo ("发送失败"); } } ?>

希望本文所述对大家php程序设计有所帮助。
