## mset, msetnx ##### *Description* Sets multiple key-value pairs in one atomic command. MSETNX only returns TRUE if all the keys were set (see SETNX). 批量设置多个KEY-VALUE。如果所有的KEYS都被设置成功，如果这些KEY-VALUE都SET成功,使用msetnx将仅仅返回一个TURE，而如果有一个是已经存在的KEY，则所有的操作都不被执行。 ##### *Parameters* *Pairs*: array(key => value, ...) ##### *Return value* *Bool*`<span class="calibre12">TRUE</span>` in case of success, `<span class="calibre12">FALSE</span>` in case of failure. ##### *Example* ``` <pre class="calibre9">$redis->mset(array('key0' => 'value0', 'key1' => 'value1')); var_dump($redis->get('key0')); var_dump($redis->get('key1')); ``` Output: ``` <pre class="calibre9">string(6) "value0" string(6) "value1" ```
