Can we edit the content of the message we sent earlier? TELEGRAM

Can we edit the content of the message we sent to Telegram earlier?

Sample;

‘Hello World’

editing
‘O world! how are you’

something like this was done but I couldn’t understand it.

 <?php

    if ($_SERVER['HTTPS'] != "on") {
    $url = "https://". $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
    header("Location: $url");
    exit;
    }

    $botToken="XXXX...";
    $website="https://api.telegram.org/bot".$botToken;

    $content = file_get_contents("php://input");
    $update = json_decode($content, true);
    $chatId = $update["message"]["chat"]["id"];
    $message = $update["message"]["text"];
    // get message_id
    $messageId = $update["message"]["message_id"];
    switch($message) {
        case("action"):
                    sendMessage($chatId, "What should I do?");
        break;

        case("add"):
        // add the 2nd parameter
            editMessageText($chatId, $messageId, "should I add?");

        break;

    default:
        sendMessage($chatId, "default");
    }

    function sendMessage($chatId, $message) {
