Cache

The cache component is a system node that is globally available. It has the purpose of collecting fresh data and serving cached data.

Cached Variable Data

  $cache_token = cache::token('nameofthiscache', $dependencies, $storage, $ttl);
  if (!$variable = cache::get($cache_token, $max_age)) {

      $variable = '...';

    cache::set($cache_token, $variable);
  }

Cached Output Recording

  $cache_token = cache::token('nameofthiscache', $dependencies, $storage, $ttl);
  if (cache::capture($cache_token, $max_age)) {

      echo 'Content that will be recorded';

    cache::end_capture($cache_token);
  }

Dependencies

The dependencies parameter are factors that should vary the cache. Examples: the session language, choice of currency, etc. The predefined list of dependencies can be found in includes/library/lib_cache.inc.php, but you can also set your own.

  $dependencies = ['language', 'currency']; // Preset example
  $dependencies = [language::$selected['code'], $my_own_variable]; // Custom example
