Outofmemory error tring debug MessageComponentInterface method vars - laravel-5

Question

In my laravel 5.7 app I use MessageComponentInterface for chat app with a class like
<?php
namespace App\Classes\Socket;
use App\Classes\Socket\Base\BaseSocket;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
class ChatSocket extends BaseSocket
{
protected $clients;
public function __construct()
{
$this->clients = new \SplObjectStorage;
}
public function onOpen(ConnectionInterface $conn) {
$this->clients->attach($conn);
echo '<pre>New Connection ::'.print_r($conn->resourceId,true).'</pre>';
}
public function onMessage(ConnectionInterface $from, $msg) {
$numRecv= count($this->clients)-1;
echo '<pre>onMessage $msg::' . print_r( $msg, true ) ;
// var_dump($from);
dump($from);
die("-1 XXZ000");
echo '<pre>onMessage $from::' . print_r( $from, true ) ;
...
The problem is that in onMessage event I want to this message write to db table, but I can not find where to get user_id of user
who sent this message?
I tried to debug outputing values to screen with
echo '<pre>onMessage $from::' . print_r( $from, true ) ;
But I got outof memmory error, but in /etc/php/7.2/cli/php.ini I modified options:
max_execution_time = 3330
max_input_time = 240
memory_limit = 4048M
and restarted my server, but anyway I got outof memory error
using these metods:
// var_dump($from);
dump($from);
I got endless output in console and I could not catch anything...
How to debug these values ?
UPDATED # 2
I try example at
https://laravel.io/forum/01-16-2015-loading-laravels-session-using-ratchet
article, but when I tried to run it with method :
public function onMessage(ConnectionInterface $from, $msg) {
$from->session->start();
$idUser = $from->session->get(Auth::getName());
I got error :
Undefined property: Ratchet\Server\IoConnection::$session
In the mentioned article there was a comment :
(you must decrypt cookie to get the session id in Laravel 5) :
I search for this I found this
In web request context cookies are usually automatically encrypted and
decrypted by the EncryptCookies middleware. So easiest option would
be just to enable this middleware (and it's enabled by default in
Laravel).
and in my app/Http/Kernel.php there is line with EncryptCookies
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
but that is web application, but I run console app.
Can the reason of the error that I have to add EncryptCookies to some other group in app/Http/Kernel.php ?
Or why error ?
Also
In file:///etc/php/7.2/cli/php.ini
I modified
memory_limit = 8048M
and restarted apache
also I tried to check how many of memory in my script :
echo '<pre>onMessage getNiceFileSize(memory_get_usage()) ::' . print_r( $this->getNiceFileSize(memory_get_usage()) , true ) ;
it shows :19241736 ~18 MiB
error message :
Out of memory (allocated 1623195648) (tried to allocate 1600131072 bytes)
I tried to calculated and got values 1.51 GiB and 1.49 GiB...
1) why memory_get_usage returns such small value 2) Why dumping gets
1.5 GiB? That is a big value 3) Any ideas how to deal it? 4) Auth::id() returns nothing and as far I understand it would not help,
as message can be sent by some other logged user, but not currently
logged...
Thanks!

Did yo see this https://laravel.io/forum/01-16-2015-loading-laravels-session-using-ratchet article ?
It has similar example :
public function onMessage(ConnectionInterface $from, $msg) {
// start the session when the user send a message
// (refreshing it to be sure that we have access to the current state of the session)
$from->session->start();
// do what you wants with the session
// for example you can test if the user is auth and get his id back like this:
$idUser = $from->session->get(Auth::getName());
if (!isset($idUser)) {
echo "the user is not logged via an http session";
} else {
$currentUser = User::find($idUser);
}
// or you can save data to the session
$from->session->put('foo', 'bar');
// ...
// and at the end. save the session state to the store
$from->session->save();
}
