How to logout a specific user programatically?

Question

I need to logout a specific user programmatically whose uid is known to me.

I think I need to destroy the session. Is there any table in drupal store that value?

Answer 1

Use drupal_session_destroy_uid function.

Ends a specific user's session(s).

Example:

drupal_session_destroy_uid($uid_to_logout);

Answer 2

I used

\Drupal::service('session_manager')->delete($uid);

for D8

Answer 3

You can condition in this code to logout user

// Programmatically logs out the current user
global $user;
$tmp = NULL;
session_destroy();
user_module_invoke('logout', $tmp, $user);
$user = drupal_anonymous_user(); //or any user you get from database
