怎样各个页面之间传递数值呢？解决办法
怎样各个页面之间传递数值呢？
1）比如以一个会员$member_no进来，怎样各个页面都得到这个值?
2)各个页面都要连同一个数据库的，怎样简化起来，不用每个页面都要写连接数据库的语句呢？
------解决方案--------------------
很初学的同学吧？
全局的变量可以使用 $_SESSION 或者 COOKIE 来设置
如果需要甚至可以用memcache 或者 redis 来配合
一般都是写好一个 conn.php 里面放置好数据库链接代码，需要的地方 include 这个文件即可.当然你高兴甚至可以使用长链接...
------解决方案--------------------
恩，写一个数据库连接文件，conn.php ,如何在需要访问数据库的页面 的 最上面 导入就可以了
