目录已创建，但在本地服务器上不存在-PHP

Question

I'm using PHP 5 and Codeigniter 3 on Ubuntu Linux.

I need to upload and store user files on the server, but before upload I need to create directory for user where files will be stored. Directory name is based on userdata hashed with md5.

Also Im checking if directory is already created/exists on server, otherwise should be created.

   public function uploadImage(){

        $id = $this->session->userdata('id');

        $dir_name = md5($id); // create hashed dir name 

        $user_dir = base_url() . 'uploads/user' . '/' . $dir_name;

       // print_r($user_dir);

        if(!file_exists($user_dir)){
            mkdir($user_dir, 0777);
            print_r("created");
        }else{
            print_r("directory exists");
        }
 }

When I run code, it says created, but I cant see directory. It does not exist in uploads/users folder. Please help me, where Im wrong. Many thanks

USE FCPATH

public function uploadImage(){

   $id = $this->session->userdata('id');

   $dir_name = md5($id); // create hashed dir name 

   /*
       You may need / after FCPATH 

       $user_dir = FCPATH . '/uploads/user/' . $dir_name;
   */

   $user_dir = FCPATH . 'uploads/user/' . $dir_name;

   // print_r($user_dir);

    if(!file_exists($user_dir)){

        mkdir($user_dir, 0777);

        // @mkdir($user_dir, 0777, true);

        print_r("created");

    } else {

        print_r("directory exists");
    }
}
