http://www.otokaze.cn/post/535.html

PHP代码稍有修改几处
v2ex_sign.php

<?php
$loginUrl = 'https://www.v2ex.com/signin'; //登录入口 
$v2ex = new v2ex('username','password'); //你的账号密码，请符合v2ex的用户名规范 
if(!is_dir("cookie")){mkdir("cookie",0755);} //检查cookie目录是否存在 
if(!is_file($v2ex->CookiePath)){ //对已有登录状态cookie的账号，程序会自动跳过登陆 
file_put_contents($v2ex->CookiePath,''); 
$v2ex->getOnceAndSession($loginUrl); //获取初始状态的once值以及SESSIONID 
$v2ex->login(); 
} 
$v2ex->getOnce('https://www.v2ex.com',$v2ex->CookiePath); //获得最新Once值，用于签到 
$v2ex->sign('https://www.v2ex.com/mission/daily/redeem',$v2ex->CookiePath); //执行签到步骤 
$v2ex->update(); //更新过期cookie

function __autoload($className){  //自动引入类库
    include $className.'.class.php';
}
