You have to load the helper. The function site_url()is provided by the urlhelper, as described here.
您必须加载助手。该功能site_url()由url帮助程序提供，如此处所述。
$this->load->helper('url');

You can try this:
你可以试试这个：
First Load the URL Helper with:
$this->load->helper('url');or set the following value inapplication/config/autoload.php$autoload['helper'] = array('url');
- Then you can show the site url with:
base_url()(result: http://example.com/) orsite_url()(result: http://example.com/index.php/)
首先加载 URL Helper：
$this->load->helper('url');或设置以下值application/config/autoload.php$autoload['helper'] = array('url');
- 然后您可以使用以下内容显示网站网址：
base_url()（结果：http: //example.com/）或site_url()（结果：http: //example.com/index.php/）
Note: Results depends on values stored in application/config/config.php
注意：结果取决于存储在 application/config/config.php
