phpmailer发送邮件及实现密码找回功能的代码

    您好!<br>  
    根据您于 [" . date('Y-m-d H:m:s') . "] 提交的请求，本邮件将引导您重新设置 [" . $account . "] 的帐号密码。  
    如果您确认本次“重新设置密码”的请求是您自己提交的，请点这里完成重设操作（本链接仅一周内、一次有效 ）。  
    如果上面的链接无法点击，您也可以复制以下链接，粘贴到您浏览器的地址栏内，然后按“回车”键打开重设机密问题页面设置新的机密问题和答案：  
    {$url}  
    如果您在以上时间点没有提交过“重新设置密码”的请求，则有可能是您机密问题的答案已经泄露，有恶意用户正在试图窃取您的帐号！";
