How to make an eternal session in PHP when logging into an account?

Question

PHP

Tell me, (just started working with PHP) how and where to write the code with remembering eternal cookies when the user logs in, so that the account is active until the user presses the logout button or clears the cookies through the browser on his own. I am attaching the login page:

<?php 
require 'db.php';

$data = $_POST;
if ( isset($data['do_login']) )
{
    $user = R::findOne('users', 'login = ?', array($data['login']));
    if ( $user )
    {
        //логин существует
        if ( password_verify($data['password'], $user->password) )
        {
            //если пароль совпадает, то нужно авторизовать пользователя
            $_SESSION['logged_user'] = $user;
            echo '<script type="text/javascript">location="index.php";</script>';
        }else
        {
            $errors[] = 'Логин или пароль не совпадают';
        }

    }else
    {
        $errors[] = 'Логин или пароль не совпадают';
    }

    if ( ! empty($errors) )
    {
        //выводим ошибки авторизации
        echo '<div id="errors" style="color:red; text-align:center;">' .array_shift($errors). '</div>';
    }

}
?>

You need to set cookies upon successful authorization, and then check them when the server session has expired.
