Code

function statistics_advanced_user_access($string, $account = NULL) {

  // If user.module is loaded, use that function call since it most likely has
  // the permissions already cached.
  if (function_exists('user_access')) {
    return user_access($string, $account);
  }
  static $perm = array();
  if (!isset($account)) {
    global $user;
    $account = $user;
  }

  // User #1 has all privileges:
  if ($account->uid == 1) {
    return TRUE;
  }

  // To reduce the number of SQL queries, we cache the user's permissions
  // in a static variable.
  if (!isset($perm[$account->uid])) {
    $result = db_query("SELECT p.perm FROM {role} r INNER JOIN {permission} p ON p.rid = r.rid WHERE r.rid IN (" . db_placeholders($account->roles) . ")", array_keys($account->roles));
    $perms = array();
    while ($row = db_fetch_object($result)) {
      $perms += array_flip(explode(', ', $row->perm));
    }
    $perm[$account->uid] = $perms;
