将以上代码保存为email.class.php

页面调用示例:

require_once ('email.class.php');

			$smtpserver = "smtp.126.com";//SMTP服务器 
			$smtpserverport =25;//SMTP服务器端口 
			$smtpusermail = "xxx@126.com";//SMTP服务器的用户邮箱 
			$smtpemailto = "yyy@126.com";//发送给谁 
			$smtpuser = "xxx";//SMTP服务器的用户帐号 
			$smtppass = "xxxx";//SMTP服务器的用户密码 
			$mailsubject = "密码找回";//邮件主题 
			$mailbody = "亲爱的用户:
请点击链接进行找回密码操作:$url 请不要将链接告诉他人,本链接24小时内有效,请尽快修改您的密码!";//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 = false;//是否显示发送的调试信息 
			$smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
