Logs and displays access statistics for a site.

Code

function statistics_exit() {
  global $user;

  // When serving cached pages with the 'page_cache_without_database'
  // configuration, system variables need to be loaded. This is a major
  // performance decrease for non-database page caches, but with Statistics
  // module, it is likely to also have 'statistics_enable_access_log' enabled,
  // in which case we need to bootstrap to the session phase anyway.
  drupal_bootstrap(DRUPAL_BOOTSTRAP_VARIABLES);
