## dump ##### Description Dump a key out of a redis database, the value of which can later be passed into redis using the RESTORE command. The data that comes out of DUMP is a binary representation of the key as Redis stores it. 把一個KEY從REIDS中銷毀(但是這個銷毀不是物理意義上銷毀),這個被銷毀的VALUE，可以使用RESTORE函數恢復出來。使用DUMP銷毀的VALUE，函數將返回這個數據在REIDS中的二進制內存地址。 ##### Parameters *key* string ##### Return value The Redis encoded value of the key, or FALSE if the key doesn't exist ##### Examples ``` <pre class="calibre16">$redis->set('foo', 'bar'); $val = $redis->dump('foo'); // $val will be the Redis encoded key value ``` ##
