Modify the title given in hook_menu() from another module

Question

How can I change the title given to the /user/[uid] page from Your account to Welcome [user name] for logged-in user, where [user name] is the username for the currently logged-in user?

Answer 1

Use hook_menu_alter.

Alter the data being saved to the {menu_router} table after hook_menu is invoked.

Code sample:

function MYMODULE_menu_alter()
{
    global $user;
    if($user->uid != 0)
        $items['user']['title'] = 'Welcome ' . $user->name;
}
