codeigniter get parameter from url

In CodeIgniter, you can retrieve parameters from the URL using the following steps:

1. First, you need to load the URL helper by using the following code: php $this->load->helper('url');

2. Then, you can use the "uri" class to retrieve the parameters. For example, to get the first parameter from the URL, you can use: php $param = $this->uri->segment(1);

If you need to get the second, third, or subsequent segments, you can simply change the segment number accordingly: php $param2 = $this->uri->segment(2); $param3 = $this->uri->segment(3);

These steps will allow you to retrieve parameters from the URL in a CodeIgniter application.
