How to restrict a menu in Drupal 7

Sometimes, we need to restrict a user from accessing a certain page.

You can do it through: hook_menu_alter()

So, if your module name is hello_world, the function should be:

function hello_world_menu_alter(&$items) {

 $items['user/%/edit']['access callback'] = FALSE;

}

Here, we have restricted user from editing profile.
