简单得像这样

echo $this->input->get('my_id');

加载URL帮助程序获取当前URL

$currentURL = current_url(); //http://myhost/main

$params   = $_SERVER['QUERY_STRING']; //my_id=1,3

$fullURL = $currentURL . '?' . $params; 

echo $fullURL;   //http://myhost/main?my_id=1,3

注意：请确保查询字符串不为空，然后连接。

在CodeIgniter中使用get请求获取当前url简单方法！
