PHP cache_helper::record_cache_set方法代码示例

 /**
  * Sends several key => value pairs to the cache.
  *
  * Using this function comes with potential performance implications.
  * Not all cache stores will support get_many/set_many operations and in order to replicate this functionality will call
  * the equivalent singular method for each item provided.
  * This should not deter you from using this function as there is a performance benefit in situations where the cache store
  * does support it, but you should be aware of this fact.
  *
  * <code>
  * // This code will add four entries to the cache, one for each url.
  * $cache->set_many(array(
  *     'main' => 'http://moodle.org',
  *     'docs' => 'http://docs.moodle.org',
  *     'tracker' => 'http://tracker.moodle.org',
  *     'qa' => ''http://qa.moodle.net'
  * ));
  * </code>
  *
  * @param array $keyvaluearray An array of key => value pairs to send to the cache.
  * @return int The number of items successfully set. It is up to the developer to check this matches the number of items.
  *      ... if they care that is.
