Class

APDQCache

A pretty darn quick cache implementation of Drupal's default cache backend.

Code

protected function prepareItem($cache) {
  if (!isset($cache->data)) {
    return FALSE;
  }

  // If the cached data is temporary and subject to a per-user minimum
  // lifetime, compare the cache entry timestamp with the user session
  // cache_expiration timestamp. If the cache entry is too old, ignore it.
  if ($cache->expire != CACHE_PERMANENT && variable_get('cache_lifetime', 0) && isset($_SESSION['cache_expiration'][$this->bin]) && $_SESSION['cache_expiration'][$this->bin] > $cache->created) {

    // Ignore cache data that is too old and thus not valid for this user.
    return FALSE;
  }

  // Inflate and unserialize data.
  apdqc_inflate_unserialize($cache);
  return $cache;
}
