PHP CURL 模拟登录 SINA 微博

最近工作上有一个需求, 需要获取 http://weibo.com/at/weibo 的数据, 就是 @我自己 的数据, 没有接口, 只能通过抓页面. 下面贴下部分代码  来自:  http://summerbluet.com/704

// 通用时间戳
define('TIMESTAMP', time());

// 出现问题的时候可以开启, 调试用的, 会在当前文件夹下面创建 LOG 文件
define('DEBUG', false);

/** 用来做模拟登录的新浪帐号 */
$username = "";
$password = "";

/* Fire Up */
$weiboLogin = new weiboLogin( $username, $password );
