新手求助，想写一个防止刷新的功能
我觉得用session应该可以实现，但是没有倒腾出来
这是我的代码
if(empty($_SESSION['online'])) //访问过 { if($_SESSION['time']+10<time())//超过10s间隔 $canpost=1; else $canpost=0; } else { $_SESSION['online']=1;//记录为访问过 $canpost=1;//允许发表 }我的想法是，没有访问过的肯定可以直接发，访问过的有一定时间间隔以后也可以发。上面的代码有什么问题么？
回复讨论(解决方案)
逻辑上有问题！
你在 $_SESSION['online'] 不为空的时候，才对 $_SESSION['online'] 赋值
