Getting messages from multiple chats madelineproto - php

Question

I am looking for some help here.
I am trying to get messages from multiple chats in Telegram using MadelineProto using the user IDs with code:
require 'vendor\autoload.php';
$settings[ 'logger' ][ 'logger' ] = 0;
$settings[ 'serialization' ][ 'serialization_interval' ] = 30;
$MadelineProto = new API('session.madeline', $settings);
$MadelineProto->async(true);
$MadelineProto->start();
$chat_one = 1234567;
$chat_two = 3254682;
$chat_three = 154789965;
function getMessagesById($u_id, $MadelineProto){
$offset_id = 0;
$limit = 100;
do {
$messages_Messages = $MadelineProto->messages->getHistory(
['peer' =>$u_id,
'offset_id' => $offset_id,
'offset_date' => 0,
'add_offset' => 0,
'limit' => $limit,
'max_id' => 0,
'min_id' => 0,
'hash' => 0 ]
);
if (count($messages_Messages['messages']) == 0) break;
print_r($messages_Messages);
$offset_id = end($messages_Messages['messages'])['id'];
yield $MadelineProto->sleep(3);
} while (true);
}
getMessagesById($chat_one , $MadelineProto);
getMessagesById($chat_two , $MadelineProto);
getMessagesById($chat_three , $MadelineProto);
But this does not return any message. I tried it by setting async to false and I get the messages only for the first function call and not two others.
Any idea here, what I am missing?
What I am actually after is only getting messages from specifics contacts and the code above works with async set to false for only one contact. I use ajax to refresh it every 10 seconds for new messages but sometimes it returns empty, so any better idea to do this would be appreciated. I went through the docs but nothing helped on getting messages, all sendMessage.
Thanks

It is necessary to transfer the object:
$inputChannel = ['_' => 'inputPeerChat', 'chat_id' => $u_id];
['peer' => inputChannel,
