php带认证的发送email函数

基于网上资料，我在sendmail函数上增加了charset参数，用于邮件主题、内容的字符集处理，其他细节有码有真相，见代码

例子：

<?php /* 这是一个测试程序!!! 请按照说明设置好以下的参数,以下是以tom.com的用户为例设置好的. */ require("smtp.php"); ########################################## $smtpserver = "tom.com";//SMTP服务器 $smtpserverport =25;//SMTP服务器端口 $smtpusermail = "zhangsan@tom.com";//SMTP服务器的用户邮箱 $smtpemailto = "lisi@tom.com";//发送给谁 $smtpuser = "zhangsan";//SMTP服务器的用户帐号 $smtppass = "xxxxxxxx";//SMTP服务器的用户密码 $mailsubject = "这是中文标题";//邮件主题 $mailbody = "<h1>This is a test mail，用于测试中文</h1>";//邮件内容 $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 = TRUE;//是否显示发送的调试信息 $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);//这些中文内容都是gb2312，默认字符集 //如果用utf-8的字符集，那么$mailsubject,$mailbody需要做一下字符集转换 //例子： $mailsubject = iconv("gb2312","utf-8",$mailsubject); $mailbody = iconv("gb2312","utf-8",$mailbody); $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype,"utf-8");//这样发送的就是utf-8字符集的邮件 ?>
