PHP的类--功能齐全的发送邮件类

PHP的类--功能齐全的发送邮件类 前面我们已经介绍过了一个用于群发邮件的类,那个类的功能只能发文本格式的邮件,下面这个类的功能则很强大,不但能发html格式的邮件,还可以发附件 <?php;; class Email;;{;;;//---设置全局变量;;var $mailTo = ""// 收件人;;;var $mailCC = ""// 抄送;;var $mailBCC = ""// 秘密抄送;;var $mailFrom = ""// 发件人;;;var $mailSubject = ""// 主题;;;var $mailText = ""// 文本格式的信件主体;;;var $mailHTML = ""// html格式的信件主体 var $mailAttachments = ""// 附件 /* 函数setTo($inAddress);;:用于处理邮件的地址 参数 $inAddress;;为包涵一个或多个字串,email地址变量,使用逗号来分割多个邮件地址;;默认返回值为true **********************************************************/;;;function setTo($inAddress){;;;//--用explode()函数根据”,”对邮件地址进行分割;;;$addressArray = explode( ",",$inAddress);;;;//--通过循环对邮件地址的合法性进行检查;;;for($i=0;$i<count($addressArray);$i++){;;if($this->checkEmail($addressArray[$i])==false) return false;;;};;
