session_id()
我在做一个网页。
把session_id()的值保存在cookie中。
然后在用到的时候从cookie中取出session_id()的值。
重新把session_id()的值放到session_id()函数中。
进而找到这个session里的变量的值。
可是session_id($_COOKIE[name])不能用啊。
怎么办?
回复讨论(解决方案)
session_id($_COOKIE[name])?为什么要这么写?
session_id($_COOKIE[name])?为什么要这么写?
您好。我想是在通过把session放到session_id()函数里载入这个ID进而调用相应的变量$_SESSION[name]
您好楼主,你这边确定$_COOKIE[name]是否有值,还有就是在session_id($_COOKIE[name])的$_COOKIE[name]是否是以“测试”这种字符串形式存在。
session跨域处理?
怎么觉得你这兜了一大圈。直接用$_SESSION['name'] = XXXXX设置,$_SESSION['name']获取不行吗?
php 默认将 sessionid 以 PHPSESSID 的名字保存于 cookie
如果需要自行处理,则 session_id($id) 需要在 session_start() 之前执行
session_start() ;先打开
