session_destroy无法破坏会话php

我有登录和注销页面，但无法注销，总是说用户已经登录。这是我的登录页面：session_destroy无法破坏会话php

<?php 


session_start(); 
    include_once("connection.php"); 
    if(isset($_POST) & !empty($_POST)) { 
    $userName = mysqli_real_escape_string($connection, $_POST['userName']); 
    $userPassword = md5($_POST['userPassword']); 
    $login = "SELECT * FROM `users` WHERE userName = '$userName' and password = '$userPassword'"; 
    $result = $connection->query($login); 
    while ($val = mysqli_fetch_array($result)) 
    { 
     $isAdmin = $val['isAdmin']; 
     $companyID = $val['companyID']; 
     $branchID = $val['branchID']; 
     $ID   = $val['ID']; 
    } 
    $count = mysqli_num_rows($result); 
    if($count == 1){ 
     $_SESSION['userName'] = $userName; 
     setcookie("userID", $ID); 
     setcookie("companyID", $companyID); 
     setcookie("branchID", $branchID); 
     if(!$isAdmin){ 
     header('location: home.php'); 
     } 
     else { 
     header('location: admin/home.php'); 
     } 
    } 
    else { 
     $fmsg = "Wrong user name"; 
    } 
    } 
    if(isset($_SESSION['userName'])){ 
    $smsg = "Already loggedin"; 
    } 
?>

这里是loggout页：

<?php 
    session_start(); 
    session_destroy(); 
    unset($_COOKIE['companyID']); 
    unset($_COOKIE['userID']); 
    unset($_COOKIE['branchID']); 
    setcookie('companyID', null, -1, '/'); 
    setcookie('userID', null, -1, '/'); 
    setcookie('branchID', null, -1, '/'); 
    header('location: index.php'); 
?>

我怎么能解决这个问题？任何人都可以帮我吗？还有一个附加的图像显示饼干。

只要使用此：

$_SESSION = array(); 
session_destroy();

在这里你可以做的是

$_SESSION['userName'] = ''; //clear userName only

并添加以下代码中的

if(isset($_SESSION['userName']) && $_SESSION['userName'] != ''){ 
    $smsg = "Already loggedin"; 
    }

或

unset($_SESSION); //all session will be gone 
$_SESSION = array(); 


// unset cookies 
if (isset($_SERVER['HTTP_COOKIE'])) { 
    $cookies = explode(';', $_SERVER['HTTP_COOKIE']); 
    foreach($cookies as $cookie) { 
     $parts = explode('=', $cookie); 
     $name = trim($parts[0]); 
     setcookie($name, '', time()-1000); 
     setcookie($name, '', time()-1000, '/'); 
    } 
}

希望这有助于

很抱歉，但couldnot进行任何更改。我有同样的问题:( –

这是我的注销页面现在 '' –

如果您打算将cookie的时间设置为减号，我的意思是这并不能解决你的问题，但它没有意义 –

这里我的代码工作对我来说

session_start(); 
unset($_SESSION['userid']); 
unset($_SESSION['username']); 
unset($_SESSION['photo']); 
session_destroy(); 
unset($_COOKIE['userid']); 
unset($_COOKIE['emailid']); 
unset($_COOKIE['photo']); 
setcookie('userid', null, -1, '/'); 
setcookie('emailid', null, -1, '/'); 
setcookie('photo', null, -1, '/'); 
header("Location:login");

不幸的是我不能为我工作 –

尝试我的模式，并告诉PHP版本 –

我觉得问题是一个与MS边工作的Firefox。感谢您对您的所有帮助我的代码是在这里：注销：

<?php 
    session_start(); 
    setcookie("branchID", "", 1); 
    setcookie("companyID", "", 1); 
    setcookie("userID", "", 1); 
    setcookie("userName", "", 1); 
    session_destroy(); 
    header('location: index.php'); 
?>

<?php 


session_start(); 
    include_once("connection.php"); 
    if(isset($_POST) & !empty($_POST)) { 
    $userName = mysqli_real_escape_string($connection, $_POST['userName']); 
    $userPassword = md5($_POST['userPassword']); 
    $login = "SELECT * FROM `users` WHERE userName = '$userName' and password = '$userPassword'"; 
    $result = $connection->query($login); 
    while ($val = mysqli_fetch_array($result)) 
    { 
     $isAdmin = $val['isAdmin']; 
     $companyID = $val['companyID']; 
     $branchID = $val['branchID']; 
     $ID   = $val['ID']; 
    } 
    $count = mysqli_num_rows($result); 
    if($count == 1){ 
     $_SESSION['userName'] = $userName; 
     setcookie("userID", $ID); 
     setcookie("companyID", $companyID); 
     setcookie("branchID", $branchID); 
     if(!$isAdmin){ 
     header('location: home.php'); 
     } 
     else { 
     header('location: admin/home.php'); 
     } 
    } 
    else { 
     $fmsg = "Hatalı Kullanıcı Adı/Şifre"; 
    } 
    } 
    if(isset($_SESSION['userName']) && $_SESSION['userName'] != ''){ 
    $smsg = "Kullanıcı Halihazırda Giriş Yapmış"; 
    } 
?>
