session_destroy ne peut pas détruire la session php

Question

J'ai des pages de connexion et de déconnexion, mais je ne peux pas me déconnecter, dit toujours l'utilisateur déjà connecté. Voici ma page de connexion:

<?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"; 
    } 
?> 

Voici la page loggout:

<?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'); 
?> 

Comment pourrais-je résoudre ce problème? Quelqu'un pourrait-il m'aider? En outre, il y a une image jointe des cookies.

Answer 1

utiliser juste ceci:

$_SESSION = array(); 
session_destroy(); 

Answer 2

Ici vous pouvez faire est

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

Et Ajouter dans votre code

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

ou

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, '/'); 
    } 
} 

Hope this helps

Je pense que problème est avec Firefox qui a travaillé avec MS Edge. Merci pour tous vos aide mon code est ici: fermeture de session:

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

connexion:

<?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"; 
    } 
?>
