用php curl模拟登陆discuz论坛

PHP支持的由Daniel Stenberg创建的libcurl库允许你与各种的服务器使用各种类型的协议进行连接和通讯。libcurl目前支持http、https、ftp、 gopher、telnet、dict、file和ldap协议。libcurl同时也支持HTTPS认证、HTTP POST、HTTP PUT、 FTP 上传(这个也能通过PHP的FTP扩展完成)、HTTP 基于表单的上传、代理、cookies和用户名+密码的认证。

php的curl真的是相当好用，网上一搜索相关文章都是关于curl模拟登陆的，很少人提供模拟discuz发贴的源码。
