会话是在后端创建和打印，而不是在前端工作

我遇到了一些奇怪的问题。

这个问题发生在服务器上。我在过去的5-6天里一直面临这个问题。它一直为我工作到去年。

当我调用登录api时，如果用户凭证是正确的，那么我创建一个会话。

if ($user){
    if ($user['is_active'] == 1){
        global $user_data;
        $user_data = $user;
        $response["error"] = false;
        $_SESSION['user_data'] = $user; // -- session is create
        print_r($_SESSION); // session is print.
        $_SESSION['is_login'] = 'No';
        unset($_SESSION['sessionX']);
        $response['user_id'] = $user['user_id'];
        $response['name'] = $user['name'];
        $response['email'] = $user['email'];
        $response['apiKey'] = $user['api_key'];
        $response['createdAt'] = $user['created_date'];
    } else {
        $response['error'] = true;
        $response['message'] = 'Your Account is Not Active';
    }
} else {
// user credentials are wrong
    $response['error'] = true;
    $response['message'] = 'Login failed. Incorrect credentials';
}

这部分的print_r:

Array
(
    [slim.flash] => Array
        (
        )
    [db_name] => arcade_intecigar
    [user_data] => Array
        (
            [user_id] => 1
            [name] => zzz
            [email] => zzz@abc.com
            [api_key] => 3fef39209b3d03039cdb81d39566eb66
            [lang_id] => en_US
            [created_date] => 0000-00-00 00:00:00
            [profile_pic] => ""
            [img] => 1461269872mk-ok.png
            [subscription_id] => 20
            [is_active] => 1
            [role_id] => 1
            [delete_permission] => 1
            [phone_number] => +14507013
            [country_code] => 1
            [total_usage_funds] => 0.0024999999441206
            [total_available_funds] => 0.99750000238419
            [paid] => trial
            [currency] => USD
        )
)

登录后，我将我的应用程序重定向到仪表板页面，并检查会话是否可用，但奇怪的是会话不可用。它总是把我重定向到登录页面。

看下面的代码

print_r($_SESSION); // it is display a blank
if (!isset($_SESSION['is_login']) && !isset($_SESSION['is_lock'])) {
    echo "<script>window.location='" . SITE_URL . "login.php?redirect=" . $_SERVER['REQUEST_URI'] . "';</script>";
}
if (isset($_SESSION['is_login']) && $_SESSION['is_login'] == 'NO' || $_SESSION['is_login']== 'No') {
    echo "<script>window.location='" . SITE_URL . "login.php?redirect=" . $_SERVER['REQUEST_URI'] . "';</script>";
}   

这部分的print_r:

Array ( [db_name] => arcade_intecigar )
