楼主问的太没水准，故上面的不给注释
下面是参数设定

// SMTP服务器地址
$smtpserver = "smtp.qq.com";
// SMTP服务器端口
$smtpserverport = 25;
// SMTP服务器的用户邮箱
$smtpusermail = "[email protected]";
// SMTP发送给谁
$smtpemailto = '[email protected]';
// SMTP服务器的用户帐号
$smtpuser = "username";
// SMTP服务器的用户密码
$smtppass = "password";
// SMTP邮件主题
$mailtitle = 'title';

// 邮件发信类
class Mail {
var $mailer;

function __construct() {
global $smtpserver;
global $smtpserverport;
global $smtpuser;
global $smtppass;

$this->mailer = new Smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass);
}

function send() {
global $view;
global $smtpemailto;
global $smtpusermail;
global $mailtitle;

$mailcontent = $view->localList() . $view->upyunList();
$mailtitle .= ' - ' . date('Ymd');
$status = $this->mailer->sendmail($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, 'HTML');

if ($status == "") {
echo 'failed';
exit();
}
echo 'succeed';
}
}

还一个方法，直接写一个JavaScript方法控制图片大小就好

我一般都这么理解的，如果html5+css3不能实现或我还没学会的东西，我就直接用JavaScript搞定…

不用<img>，用background

background-size: cover;
background-position: center;

奥巴马左手右手都会写字

自己写一个chrome扩展用content scripts搞定，十分钟就搞定了

@582033 谢谢，看来我还是用原生的OpenWrt的好，小米乱七八糟的东西太多，很多事情都在我的掌控之外令我很是苦恼

真的假的，只要会用HTML+CSS+JavaScript基础支持+jQuery就能10K？

实习生水平就能10K，不可思议。

这门槛也太低了吧，我不信，如果哪里有这种公司，请联系我，我初中的时候就已经会了。

去年又拍云送了我一张4999的TechCrunch门票，包午餐那种，我就一直在使用又拍云了

@chengzhoukun 是的！

补充一下，做题就是考你的解决问题的能力，是否被剃掉也要看这一波来面试的人的质量如何

以前看书见过一道题是要你编程控制CPU占用率呈现正弦曲线形态

你估摸估摸
