    Your title is about 7, and question body about 8. Voting to close as unclear now.

  • $user = User::load($uid); $userName = $user->getUsername();

  • In Drupal 8 - $current_user = \Drupal::currentUser(); $user_name = $current_user->getAccountName();

You can use user_load or \Drupal\user\Entity\User::load to do this. Below code will provide the solution

 public function content() {
     $account = \Drupal\user\Entity\User::load('uid'); // pass your uid
     $name = $account->getUsername();
     drupal_set_message($name);
 }

$name gives the username of the user.

    link for user_load is depreciated, you should probably use Entity::load api.drupal.org/api/drupal/…

    Using $account->getDisplayName() will help ensure you get any altered value of the username.

    /Drupal/Core/Session/AccountInterface::getUsername() is deprecated in Drupal 8.0.0, will be removed before Drupal 9.0.0. Use /Drupal/Core/Session/AccountInterface::getAccountName() or /Drupal/user/UserInterface::getDisplayName() instead. See drupal.org/node/2572493

In D8, if you don't know the uid, you can do this:

function test_user_login(\Drupal\Core\Session\AccountInterface $account) {
   $account = \Drupal\user\Entity\User::load(\Drupal::currentUser()->id());
   $user = $account->get('name')->value;
   drupal_set_message($user, 'status'); }

There are several ways to get the user's name programmatically

$account = \Drupal\user\Entity\User::load(1); // pass your uid    
//1 
drupal_set_message($account->name->value);    
//2
drupal_set_message($account->get("name")->value);    
//3
drupal_set_message($account->getUsername());
//4
drupal_set_message($account->name->getValue()[0][value]);

    in drupal 9, getUsername() was changed to getAccountName();

You can use user_load($uid); This will return a fully loaded User object(in D7).

$user = user_load($uid);
print $user->name;

This should print the user name.
