Question

我已经尝试了2个小时在我的页面上设置cookie并且在网上阅读了很多，我仍然无法找出我做错了什么。这是我的代码：

<?php

$cookie_name = "user";
$cookie_value = "MyUserName";

$days = 86400*30;
$cookie_time = $days+time();

setcookie($cookie_name, $cookie_value, $cookie_time, '/');

if (!isset($_COOKIE[$cookie_name]))
{
   echo "Cookie named '" . $cookie_name . "' is not set!";
}
else
{
echo "Cookie '" . $cookie_name . "' is set <br/>";
echo "Value is: " . $_COOKIE[$cookie_name];

?>

我的Echo的结果是“未命名Cookie'用户'！”每次！有人能帮助我吗？：）

Answer 1

你的代码中有语法错误你错过了colse the else statment

试试这个，然后你的代码将设置cookie

$cookie_name = "user";
$cookie_value = "MyUserName";

$days = 86400*30;
$cookie_time = $days+time();

setcookie($cookie_name, $cookie_value, $cookie_time, '/');

if (!isset($_COOKIE[$cookie_name]))
{
   echo "Cookie named '" . $cookie_name . "' is not set!";
}
else
{
echo "Cookie '" . $cookie_name . "' is set <br/>";
echo "Value is: " . $_COOKIE[$cookie_name];
}

Answer 2

您忘记关闭else声明：

else
{
echo "Cookie '" . $cookie_name . "' is set <br/>";
echo "Value is: " . $_COOKIE[$cookie_name];

提示：您应该通过将此代码添加到PHP文件的顶部来启用Error Reporting，这将有助于您查找错误。

<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

setcookie（）不起作用
