Session is create and print in backend but not work in frontend

问题

I am facing some strange issue.

This problem happens on server. I am facing this problem since last 5-6 days. It was working for me until last 1 year.

When I call a login api, if user credential is right then I create a session.

Here is my code:

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';
}

print_r of this portion:

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
        )

)

After login, I am redirecting my app to dashboard page and check that if session is available or not, but it is strange that session is not available. And it is always redirecting me to the login page.

Look below code.

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>";
}

print_r of this portion:

Array ( [db_name] => arcade_intecigar )

回答1:

This problem is happen because , on server there is no inode memory is avaiable for more session create , as per my knowledge when session is create in php that time session file is also create , so there is no memory is available that's why session is not create .

Use df -i command for know the inode memory on server.
