PHP Telegram Bot (editMessageText & editReplyMarkup) - php

Question

I am Kevin and these days I'm having problems with the functions editMessageText and editReplyMarkup. This is my code and I don't know where is the problem.
This is my code:
<?php
$botToken = "XXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
$website = "https://api.telegram.org/bot".$botToken;
$FilejSon = file_get_contents("php://input");
$FilejSon = json_decode($FilejSon, TRUE);
$FirstName = $FilejSon["message"]["chat"]["first_name"];
$UserChatId = $FilejSon["message"]["chat"]["id"];
$Message = $FilejSon["message"]["text"];
$MessageID = $FilejSon["message"]["message_id"];
$CallBackID = $FilejSon["callback_query"]["from"]["id"];
$CallBackData = $FilejSon["callback_query"]["data"];
$what = ["callback_query"]["message"]["inline_message_id"];
$document = "http://media.giphy.com/media/109Ku3hdapZJle/giphy.gif"; //It's just a funny image
//Emoji
$phone = json_decode('"\uD83D\uDCF2"');
$list = json_decode('"\uD83D\uDCCB"');
$money = json_decode('"\uD83D\uDCB0"');
$postbox = json_decode('"\uD83D\uDCEE"');
$sos = json_decode('"\uD83C\uDD98"');
$link = json_decode('"\uD83D\uDD17"');
$jSonCodeKeyboard = '&reply_markup={"inline_keyboard":[[{"text":"1","url":"https://core.telegram.org/bots/api"}],[{"text":"2","url":"https://www.google.it"}],[{"text":"4","switch_inline_query_current_chat":"try"}],[{"text":"5","url":"https://www.google.it"},{"text":"'.$link.'%20Link%20'.$link.'","url":"http://botkevin.altervista.org/Bot/Nuovo_documento_di_testo.txt"}],[{"text":"6","callback_data":"Press"}]]}';
$jSonCodeKeyboard1 = '&reply_markup={"inline_keyboard":[[{"text":"Indietro","callback_data":"Ok"}]]}';
switch ($Message){
case '/start':
$msg = "Hello $GLOBALS[FirstName] $GLOBALS[MessageID] $GLOBALS[UserChatId] $GLOBALS[what].\n";
sendMessage($UserChatId, $msg, $jSonCodeKeyboard);
break;
case '/prova':
sendFile($UserChatId, $document);
break;
case '/prova1':
$msg = "worked $GLOBALS[MessageID]";
sendMessage($UserChatId, $msg, $jSonCodeKeyboard1);
break;
default:
if (callback($FilejSon)){
if ($CallBackData == "Press"){
sendMessage($CallBackID, "gg", $jSonCodeKeyboard1);
}
else if($CallBackData == "Ok")
{
$msg = "Edited";
Edit($CallBackID, $MessageID, $msg);
Edit1($CallBackID, $MessageID, $jSonCodeKeyboard1);
}
}
$msg = "Unrecognized command.";
sendMessage($UserChatId, $msg);
break;
}
function sendMessage($chat_id, $text, $LayoutKey){
if($LayoutKey==""){
$url = $GLOBALS[website]."/sendMessage?chat_id=".$chat_id."&text=".urlencode($text);
file_get_contents($url);
}
else{
$url = $GLOBALS[website]."/sendMessage?chat_id=".$chat_id."&text=".urlencode($text).$LayoutKey;
file_get_contents($url);
}
}
function sendFile($chat_id, $file){
$url = $GLOBALS[website]."/sendDocument?chat_id=".$chat_id."&document=".$file; //Gif,Pdf e Zip
file_get_contents($url);
}
function Edit($chat_id, $msgID, $text){
$url = $GLOBALS[website]."/editMessageText?chat_id=".$chat_id."&message_id=".$msgID."&text=".urlencode($text);
file_get_contents($url);
}
function Edit1($chat_id, $msgID, $LayoutKey){
$url = $GLOBALS[website]."/editMessageReplyMarkup?chat_id=".$chat_id."&message_id=".$msgID.$jSonCodeKeyboard1;
file_get_contents($url);
}
function callback($getUpdate){
return $getUpdate["callback_query"];
}?>
I've searched everywhere a solution but either were in another programming language or used a library and more, I'm not very good at php so i would like a basic thing like my code.
I would like to do that when I click on the inline keyboard of the first message that sends the bot by doing "/ start", clicking a button can modify the message and the inline keyboard without sending other messages clogging the chat.
