How to use setcookie() to assign value to cookie in php

This morning I wanted to make a function. After the user logged in, I saved the user's name in a cookie, but I started to use the method of reading the cookie, but it didn't work. Later I found that using setcookie() must be followed by time. Below I Let me introduce it.

Grammar
setcookie(name,value,expire,path,domain,secure)

Parameter Description
name required. Specifies the name of the cookie.
value required. Specifies the value of the cookie.
expire is optional. Specifies the validity period of the cookie.
path is optional. Specifies the server path for cookies.
domain is optional. Specifies the domain name for the cookie.
secure Optional. Specifies whether cookies are transmitted over a secure HTTPS connection.

For example, a simple assignment to a cookie

The code is as follows

代码如下

复制代码

$value = "my cookie value";

// 发送一个 24 小时候过期的 cookie
setcookie("TestCookie",$value, time()+3600*24);
?>

Copy code

$value = "my cookie value";

代码如下

复制代码

$cart_info[0][0] = "1123";
$cart_info[1][0] = "5334521";
$cart_info[1][2] = "df";
$cart_info[4][2] = "fefe";

setcookie("xia",serialize($cart_info));
?>

//Send a cookie that expires in 24 hours

setcookie("TestCookie",$value, time()+3600*24);

代码如下	复制代码
$other = StripSlashes($_COOKIE['xia']); print_r(unserialize($other)); ?>
