PHP curl模拟登录带验证码的网站

需求是这样的，需要登录带验证码的网站，获取数据，但是不可能人为一直去记录数据，想通过自动采集的方式进行，如下是试验出来的结果代码！有需要的可以参考下！

<?php

  }

    foreach($this->cookiename as $key => $name)
    {
      $this->cookiepathfile[] = root_path . $this->cookiepath . $this->cookiename[$key] . '_xxx.txt';
    }
  }

登录以后，就可以使用带cookie的访问其他页面了！
