有关php, mysql从数据库提取并保存到一个PHP文件中
打个比方
以论坛来说,各讨论版块表应该有2个基本数值
1. fid
2. name
但如果人流多次,我不想每次看到fid都向数量库差查 fid=1 是什么name fid2 又是什么name
能不能做成每次改了 这张表之后,或者做了某个动作后
就会从数据库查询一次,然后保存到一个php文件中(当作缓存),保存为一个数组
每次用户浏览时,模板中预到fid 都是去找那个缓存的php文件,去该数组中找相关资料
这样该如何做到?
------解决方案--------------------
程序文件是文件,表也是文件
反正都是在文件里查,何必多次一举
------解决方案--------------------
如果不需要運算,而是直接讀取的,查數據庫比查文件快。
------解决方案--------------------
如果内存足够大,可以放内存中。
------解决方案--------------------
用memcache缓存
