删除用户cookie

Question

我能够正确地设置一个用户cookie，但是它不会在用户注销时被销毁或终止。任何帮助都将不胜感激！我还不熟悉php和学习。

这是我的密码：

page1.php

<?php
    session_start();
    if(isset($_POST['txtusername']) && isset($_POST['txtpassword'])){
        $_SESSION['username'] = $_POST['txtusername'];
        $_SESSION['usertype'] = $_POST['usertype'];
        $username = $_SESSION['username'];
        setcookie("Activity99", $username, time()+3600);
        echo "<font class = 'user'>".$username."</font>"."<br>";
    }
?>

page2.php

<form method="POST" action="login.php">
    <label><?php echo "<font class = 'user'>".$username."</font>";?>
    <input type="submit" name="logout" value="Logout" class= "logout">
    </label>
</form>

<?php
    if(isset($_POST['logout'])){
        if(isset($_COOKIE['Activity99'])):
            setcookie('Activity99', $username, time()-3600,);
        endif;
    }
?>

Answer 1

根据实际读取登录状态的方式，您还必须结束会话：

session_start();
$_SESSION = [];
setcookie("Activity99", "", time() - 3600);
header("Location:  index.php?info=success");
die();

Answer 2

试试这个：

unset($_COOKIE['your cookie name']); 

或者：

setcookie('your cookie name','');
