Create own bot on telegram with php - php

Question

I saw a couple of days ago this tutorial on youtube.
It was very interesting, so I decided to make a own bot.
I used the code from the tutorial as a template:
<?php
$bottoken = "*****";
$website = "https://api.telegram.org/bot".$bottoken;
$update = file_get_contents('php://input');
$updatearray = json_decode($update, TRUE);
$length = count($updatearray["result"]);
$chatid = $updatearray["result"][$length-1]["message"]["chat"]["id"];
$text = $updatearray["result"][$length-1]["message"]["text"];
if($text == 'hy'){
file_get_contents($website."/sendmessage?chat_id=".$chatid."&text=hello");
}
elseif($text == 'ciao'){
file_get_contents($website."/sendmessage?chat_id=".$chatid."&text=bye");
}
The script worked if I execute the script manually. However when I use the webhook it doesn't work anymore. The tutorial said that $update = file_get_contents('php://input'); is the right way, to be used before $update = file_get_contents($website."/getupdates");. My question how can I use php://input to execute my script automatically? The script is on a server from "one.com" and the certificate is also from "one.com".

Answer 1

If you use selfsigned ssl you have to point to the ssl path ,,
use the ssh to run this command after filling it with your real data ,,
curl -F "url=https://example.com/myscript.php" -F "certificate=#/etc/apache2/ssl/apache.crt" https://api.telegram.org/bot<SECRETTOKEN>/setWebhook

After change to WebHook method, you need to put as follows, since now we are going to handle one message at time. For me works perfectly.
instead
$chatId = $updateArray["result"][0]["message"]["chat"]["id"];
to
$chatID = $update["message"]["chat"]["id"];

Answer 3

this is the answer for all of your problems.
follow this step after you got a secret token for your bot:
create file in your website https://yourdomain.com/secret-folder/index.php
create your php file like this :
<?php
$website = 'https://api.telegram.org/bot123456789:1234567890ABCDEF1234567890ABCDEF123/';
$content = file_get_contents("php://input");
$update = json_decode($content, true);
if (isset($update["message"])){
$chatID = $update["message"]["chat"]["id"];
$text = $update["message"]["text"];
if ( $text == '/start' ) {
// send welcome message
file_get_contents($website."sendMessage?chat_id=".$chatID."&text=Welcome to my bot");
}else{
// send another message or do your logic (up to you)
file_get_contents($website."sendMessage?chat_id=".$chatID."&text=some text here");
}
}
?>
Set Your Webhook from this bot #set_webhookbot
choose command or type ' ست وب هوک '
reply with your secret bot token ex: ' 123456789:1234567890ABCDEF1234567890ABCDEF123 '
reply with your webhook address 'https://yourdomain.com/secret-folder/index.php'
reply with /setwebhook
if you follow step by step its will work.
enjoy it !!

Sorry for digging up this old question so enthusiastically, I had exactly the same question as you.
I think actually the answer may be easier yet less satisfying as we hoped: I don't think it's possible to get a list of previous messages to the bot while using the webhook.
Namely: what this does, is run the PHP script directly as soon as the bot receives a message. Nothing is stored in an accessible database, hence no updateArray is returned.
I came across this example, which shows how php://input works. I guess the solution to display a list of messages would be, let the php script store the message in a database everytime a message is 'forwarded' via the webhook.
If anyone found something else: I'm very interested.

As per my understanding from your code snippet above, you need to use php://input within double quotes instead of single quotes. In php, we are having bing difference in this use case.
