SAE里面有Memcache，可以较大幅度改善数据库的鸭梨~

之前一直想学习Memcache，却愁于不知如何下手，对这个名词完全没有概念，同时在SAE的文档里面，也很少对于Memcache的使用教程~

刚才在写一个作业，突然想起Memcache，就再次尝试，终于知道怎么用了~

上面是在SAE里面，用PHP脚本来使用Memcache的方法~

## 在自己的SAE项目里面，激活Memcache功能 ##

> 1.  进入你的新浪云平台，选择要设置的应用，进入管理页面
> 2.  选择服务管理下的Memcache这个链接，点击一下
> 3.  进入Memcache这个页面，选择“点此初始化MC”这个按钮，更具自己网站的需求设置缓存的容量，当你输入的时候会提示你该设置下要消耗多少云豆，建议大家认真设置，如果设置不合理，导致云豆的巨大浪费，或者没有发挥到Memcache的真正作用。

我设置了10M的Memcache，提示每天用1.9几的云豆~

## 部分代码解释 ##

第一个参数是数据的key，用来定位一个数据，第二个参数是需要保存的数据内容，这里是一个字符串，第三个参数是一个标记，一般设置为0或者MEMCACHE\_COMPRESSED就行了，第四个参数是数据的有效期，就是说数据在这个时间内是有效的，如果过去这个时间，那么会被Memcache服务器端清除掉这个数据，单位是秒，如果设置为0，则是永远有效。
