php - Remove specific segment from a URL -

i using codeigniter 2.xx, , view code:

<a  href="users/user_info/<?=$row->user_name;?>/<?php echo $row->user_id;?>"></a> 

and controller code:

function user_info($name, $id) {        $info['info']       =   $this->user_model->user_info($id);     $data['content']    =   $this->load->view('home',$info,true);     $this->load->view('template',$data); } 

when click on link url: http://localhost/users/user_info/name/id

i want remove last id segment url becomes: http://localhost/users/user_info/name. how can this? read uri segment doesn't solve question.

if you're trying current url , remove /id it, simply:

$url = $_server["request_uri"];  $paths = explode('/', trim(parse_url($url, php_url_path), '/'));  unset($paths[count($paths)-1]);  $new_url = '/' . implode('/', $paths);  echo $new_url; 

which removes last url segment, outputting /users/user_info/name if visiting page /users/user_info/name/id

alternatively, change $url string in href="...", again couldn't remove code directly href?
