示例1: cas
/**
* Performs a "check and set" to store data.
*
* The set will be successful only if the no other request has updated the value since it was fetched since
* this request.
*
* @link http://www.php.net/manual/en/memcached.cas.php
*
* @param float $cas_token Unique value associated with the existing item. Generated by memcached.
* @param string $key The key under which to store the value.
* @param mixed $value The value to store.
* @param string $group The group value appended to the $key.
* @param int $expiration The expiration time, defaults to 0.
* @param string $server_key The key identifying the server to store the value on.
* @param bool $byKey True to store in internal cache by key; false to not store by key
* @return bool Returns TRUE on success or FALSE on failure.
