Question

我有以下PHP代码用于检查我的index.php中的登录

<?php
session_start();

$con = mysqli_connect("***", "***", "***", "***");

$fbid_check=$_SESSION['loginid_session'];
$fbphoto_session=$_SESSION['loginphoto_session'];

$fbname_sql=mysqli_query($con, "SELECT fb_name FROM uni_users WHERE fb_id='$fbid_check' ");
$name_fetch=mysqli_fetch_array($fbname_sql, MYSQLI_ASSOC);

$fbname_session=$name_fetch['fb_name'];

if(isset($fbname_session))
 {
    header("location: http://www.uniwink.com/landing/profile.php");
 }
mysqli_close($con);


?>

这将检查登录并重定向到profile.php，其中标题中包含以下PHP代码以检查登录

<?php
$con = mysqli_connect("****", "****", "****", "****");

session_start();
$fbid_check=$_SESSION['loginid_session'];
$fbphoto_session=$_SESSION['loginphoto_session'];

$fbname_sql=mysqli_query($con, "SELECT fb_name FROM uni_users WHERE fb_id='$fbid_check' ");
$name_fetch=mysqli_fetch_array($fbname_sql, MYSQLI_ASSOC);

$fbname_session=$name_fetch['fb_name'];

if(!isset($fbname_session))
{
   header("location: http://www.uniwink.com/landing");
}

mysqli_close($con);


?>

我有以下logout.php，它来自profile.php

<?php
session_start();
unset($_SESSION['loginid_session']);
unset($fbname_session);
session_destroy();
header("location: http://www.uniwink.com/landing");
exit();

?>

问题是在注销后，它仍然进入profile.php。就像会话没有被破坏一样。事情是它一直工作到昨天，并突然发生。感谢

Answer 1

尝试将session_start();移到mysql连接上方。

变化

$con = mysqli_connect("****", "****", "****", "****");
session_start();

到

session_start();
$con = mysqli_connect("****", "****", "****", "****");

也使用isset with session

if (isset($_SESSION['loginid_session'])){ 
   .....
}

Answer 2

尝试在注销时添加以下内容;

$_SESSION = array();
if (ini_get("session.use_cookies"))
{
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

注意：这会破坏会话 - 而不仅仅是会话数据。

Answer 3

检查会话。

if (isset($_SESSION['loginid_session'])) 
{
    header("location: http://www.uniwink.com/landing/profile.php");
}
else
{
    header("location: http://www.uniwink.com/landing");
}

PHP会话不会破坏或取消设置
