Loads a user object.
Drupal has a global $user object, which represents the currently-logged-in user. So to avoid confusion and to avoid clobbering the global $user object, it is a good idea to assign the result of this function to a different local variable, generally $account. If you actually do want to act as the user you are loading, it is essential to call drupal_save_session(FALSE); first. See Safely impersonating another user for more information.
int $uid: Integer specifying the user ID to load.
bool $reset: TRUE to reset the internal cache and load from the database; FALSE (default) to load from the internal cache, if set.
object A fully-loaded user object upon successful user load, or FALSE if the user cannot be loaded.
function user_load($uid, $reset = FALSE) {
return entity_load('user', $uid, $reset);
}
