实战中redis怎么用
我们现在网站用到了redis数据库,我虽然也明白那些get set操作,可是最终没有时间过,实战中怎么配合mysql数据库用的尼?
------解决思路----------------------
把查询的结果集压缩之后保存 

<br />if ($redis->get('key')){<br />$result = $redis->get('key');<br />$result = unserialize($result);<br />}else{<br />//查询数据库<br />$result = mysql_query($sql);<br />while($row = mysql_fetch_array()){<br />    $arr[] = $row;<br />}<br />$arr = serialize($arr);<br />$redis->set('key',$arr);<br />}<br />
Copy after login
Copy after login

------解决思路----------------------
不是说 redis 优于 memcache 吗?
那么 memcache 可以直接存储 php 的数组和对象,为何 redis 不可以呢?

------解决思路----------------------
redis里包括String、List、Set、Zset、Hash数据类型,看你的数据在应用场景了,mc与redis都可以做为缓存来应用,从mysql取出数据后,就看mc或redis的应用了
