The Cookie 輔助函數 file contains functions that assist in working with cookies.
載入輔助函數
輔助函數使用下列方式載入：
$this->load->helper('cookie');
可用函數如下所示：
set_cookie()
This helper function gives you view file friendly syntax to set browser cookies. Refer to the Input class for a description of use, as this function is an alias to $this->input->set_cookie().
get_cookie()
This helper function gives you view file friendly syntax to get browser cookies. Refer to the Input class for a description of use, as this function is an alias to $this->input->cookie().
delete_cookie()
Lets you delete a cookie. Unless you've set a custom path or other values, only the name of the cookie is needed:
delete_cookie("name");
This function is otherwise identical to set_cookie(), except that it does not have the value and expiration parameters. You can submit an array of values in the first parameter or you can set discrete parameters.
delete_cookie($name, $domain, $path, $prefix)
