问题描述
我有一个网站,每次加载/刷新页面时都会生成一个 uuid.我想使用 cookie 使某个值在一段时间内保持不变.有谁知道可以帮助我的脚本?
I have a website which generates a uuid every time the page is loaded/refreshed. I want to make it so that a certain value remains the same for a period of time using cookies. Does anyone know of a script which can help me?
推荐答案
不确定你为什么要脚本,或者这里的问题是什么.要设置 cookie,只需使用:
Not sure why you are asking for a script, or what the problem here is. To set a cookie, just use:
if (empty($_COOKIE["uuid"])) {
$uuid = uniqid(); // or use a real UUID
setcookie("uuid", $uuid, time()+30*24*60*60, "/");
}
else {
$uuid = $_COOKIE["uuid"];
}
实际上,您应该偶尔执行一次 setcookie 以刷新 cookie 生存期.
Actually you should execute the setcookie once in a while and anyway to have the cookie lifetime refreshed.
