How to set messages as read after getUpdates?

Question

PHP

I receive messages by url, how can I set them as read after receiving them, so that they do not come again?
Google did not give an answer
Api telegram is not entirely clear

Answer 1

Use getWebhookUpdates

Answer 2

Add getUpdates ?offset=[update_id]
update_id - from the response, can be stored in a file or database, updating when it changes the
message will only come to those who have update_id > given

Answer 3

You don't need to store anything. I did so

/**
 * @return void
 */
public function processUpdates()
{
    $updates = $this->api->getUpdates();
    $lastUpdateId = null;
    foreach ($updates as $update) {
        $lastUpdateId = $update->getUpdateId();
        $this->processUpdate($update);
    }
    if ($lastUpdateId) {
        $this->api->getUpdates($lastUpdateId + 1, 1);
    }
}

1. Get a list of messages, keeping the last received id
   
2. We process them
   
3. Once again we get a list of messages, specifying the offset in "{last received id} + 1"
   
4. The next receipt of a list of messages without parameters will display only the messages that were not received before this
