Sending Image via Telegram-Bot API with PHP

Solution:

You usedsendMessage method, And this method isn't acceptphoto parameter.

And$url shouldn't be concatenated with another link.

To send photo usesendPhoto method like this:

<?php
function suspendido($chat_id, $url, $foo) 
{
  $TOKEN = "<bot_token>";
  $TELEGRAM = "https://api.telegram.org:443/bot$TOKEN"; 
  $url = "https://zrabogados-pruebas.xyz/bot/404.png";
  $query = http_build_query(array(
    'chat_id'=> $chat_id,
    'photo'=> $url,
    'text'=> $foo,
    'parse_mode'=> 'HTML' // Optional: Markdown | HTML
  ));
  
  # Use sendPhoto here, Not sendMessage
  $response = file_get_contents("$TELEGRAM/sendPhoto?$query");
  return $response;
}

Copy code

Solution:

Apparently, there is some problem with telegram servers.

If you put some image attributes into url it works.

function suspendido($chat_id,$foo) 
{
  $TOKEN = "blablalbla";
  $TELEGRAM = "https://api.telegram.org:443/bot$TOKEN"; 
  $url    = "https://zrabogados-pruebas.xyz/bot/404.png?center=140.50,36.15&width=1024&height=576";
  $query = http_build_query(array(
    'chat_id'=> $chat_id,
    'photo'=> $url,
    'text'=> $foo,
    'parse_mode'=> "HTML", // Optional: Markdown | HTML
  ));
  $response = file_get_contents("$TELEGRAM/sendMessage?$query");
  return $response;

}
Copy code

I know its just silly but it works that way if you send the image url without this then you will receive a 400 error.
