示例1: replace
/**
* Replaces a value in cache.
*
* This method is similar to "add"; however, is does not successfully set a value if
* the object's key is not already set in cache.
*
* @link http://www.php.net/manual/en/memcached.replace.php
*
* @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.
