login / register snippet help

Good day,
I'd like to implement the php snippet in the Internet_services theme into my own theme but unsure how to do it can you please assist me?

I tried placing the code from the search-theme-form.tpl.php into the page tpl directly but it didn't work.

here is your code:

  global $user;

  if (!$user->uid) {
    $message .= '<div>' . t('Please <a href="@login">Login</a> or <a href="@register">Register</a>', array('@login' => url('user/login'), '@register' => url('user/register'))) . '</div>';
    $message .= '<div>' . t('<a href="@password">Request New Password</a>', array('@password' => url('user/password'))) . '</div>';
  } 
  else {
    $message .= '<div>' . t('Welcome @user', array('@user' => $user->name)) . '</div>';
    $message .= '<div>' . t('<a href="@view">View</a> | <a href="@edit">Edit</a> | <a href="@logout">Logout</a>', array('@view' => url('user/' . $user->uid), '@edit' => url('user/' . $user->uid . '/edit'), '@logout' => url('logout'))) . '</div>';
  }

function phptemplate_search_theme_form($form) {
  return _phptemplate_callback('search-theme-form', array('form' => $form));
}

function internet_services_primary($items = array()) {
  $menu = menu_get_item(variable_get('menu_primary_menu', 0));
  $output = '<div class="title">' . $menu['title'] . '</div>';
  $output .= theme('links', $items);
  return $output;
}
