How to make a questionnaire type in Telegram bot?

Question

PHP

Good day everyone, like when you click on the button:
Continue the dialogue with the bot so that the bot remembers previous answers

<?php
include('db.php'); // Подключаем БД
include('../vendor/autoload.php'); //Подключаем библиотеку
use Telegram\Bot\Api;

/*
* Собираем данные с балансами
*/

$telegram = new Api('APITOKEN'); //Устанавливаем токен, полученный у BotFather
$result = $telegram -> getWebhookUpdates(); //Передаем в переменную $result полную информацию о сообщении пользователя

$text = $result["message"]["text"]; //Текст сообщения
$chat_id = $result["message"]["chat"]["id"]; //Уникальный идентификатор пользователя
$name = $result["message"]["from"]["username"]; //Юзернейм пользователя
$keyboard = ; //Клавиатура


if($text){
    if ($text == "/start") {
        $reply = "\xF0\x9F\x8E\xAC Добро пожаловать в сервис
            Если вы готовы к заказу нажмите <code>Заказать</code>";

        $reply_markup = $telegram->replyKeyboardMarkup([ 'keyboard' => $keyboard, 'resize_keyboard' => true, 'one_time_keyboard' => false ]);
        $telegram->sendMessage([ 'chat_id' => $chat_id, 'parse_mode' => 'HTML', 'text' => $reply, 'reply_markup' => $reply_markup ]);
        
        //Проверяем есть ли такой Chat_ID в БД
            $result = mysqli_query($db, "SELECT * FROM bot_kino_user WHERE chat_id LIKE '%".$chat_id."%'");
                if (mysqli_num_rows($result) == 0) {
                    $userlogin = $name;
                    mysqli_query ($db,"INSERT INTO `bot_kino_user` (`chat_id`, `username`) VALUES ('$chat_id', '$userlogin')");//добавление в базу
            }
            
    }elseif ($text == "\xF0\x9F\x8E\xAC Заказать") {
        $reply = "Для заказа пришлите: 
        1. Город
        2. Возраст
        3. Имя";
        
        $telegram->sendMessage([ 'chat_id' => $chat_id, 'text' => $reply ]);
    }

After pressing the "Order" button
You need to ask - City
Save
Ask - Age
Save
Ask - Name
Save
Next, we show the entered data, and ask if everything is correct, if yes
Then we return to the main menu
I was looking for examples, I did not find this anywhere ..
Help someone with what can please)

Answer 1

Your logic is lame, you yourself write in the example, for example "city: your city"
therefore it should work something like this:
bot:

Для заказа билета пришлите: 
        Пример - Город: Ваш город"

You: Город: Москва
bot:

Ваш город Москва, введите Кинотеатр (пример: Кинотеатр: Ваш Кинотеатр)

You: Кинотеатр: Восход
etc...
and, accordingly, first check the text for compliance with the beginning (to find the City: or Cinema: , and after the colon, then search until the end of the line that you wrote there.
ps such logic is terrible, a normal person will not use it)
If you do it humanly, then the bot should ask ... What city? and remembers the step="city" variable, then with any user's answer, it looks at what is in the step variable, understands what stage it is at, remembers the user's answer, asks a new question and put a new stage in the step variable, for example step="cinema"

Answer 2

Store in variables.
I wrote in python, but the essence is the same - you declare a variable, write the answer into it, then output it at the end and, if necessary, save it to the database.

Answer 3

It may be useful for someone, I developed the following code a little further:
(I can’t save the value of the variable within the script yet, empty variables are written to the database)

elseif ($text == "\xF0\x9F\x8E\xAC Заказать билет") {
        $reply = "Для заказа билета пришлите: 
        Пример - <code>Город: Ваш город</code>";
        
        $telegram->sendMessage([ 'chat_id' => $chat_id, 'parse_mode' => 'HTML', 'text' => $reply ]);
        
    }elseif(strstr($text, "Город")){
            
            $_SESSION['city'] = $text;
            $city = $_SESSION['city'];
            
            $reply = "$city - Сохранен! \nПример - <code>Кинотеатр: Ваш кинотеатр</code>"; 
            
            $telegram->sendMessage([ 'chat_id' => $chat_id, 'parse_mode' => 'HTML', 'text' => $reply ]);
