You need to set a private variable inside the containing class e.g. private link and then set it inside your page function like $this->link = $data['link'] and then use $this->link to reference it in employee. — iSZ, Dec 07 '17 at 01:03
I've added an example below. Is your code inside a CI class, something like below? — iSZ, Dec 07 '17 at 01:53

Update your method like the following

private function page() {
$page_id = $this->uri->segment(3);
$page_details = $this->m_module->submenu($page_id)->row_array();

return [
    'title' => $page_details['sub_title'];
    'menu' => $page_details['title'];
    'submenu' => $page_details['sub_title'];
    'link'=> $page_details['sub_target'];
    'page_id' => $page_id;
];

}

private function employee() {
  $data = $this->page();
  $data['employee']= $this->m_module->employee()->result_array();
 $this->template->display($data['link'],$data);
}

The reason you were not getting was because your method was not returning as value.

You can set a class variable to pass the value of link between functions

<?php
    class MyController extends CI_Controller {
        private $link;

        public function page($data){
            $this->link = $data['link'];
        }

        public function page(){
            echo $this->link;
        }

    }
?>
