curl post multipart/form-data api - php

Question

I can not send pictures.
More information - Telegram
https://core.telegram.org/bots/api#sendphoto
I want to send a picture, this method is useless.
Are there any other method?
<?php
$Photo = "http://www.pawprint.net/images/news/1-4fac83467069c.png";
$IDUser = 26034352;
$Data = array(
'chat_id' => $IDUser,
'photo' => $Photo,
'caption' => 'hi'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://api.telegram.org/bot93816942:AAHnjqsjpJjRItc7ySbUq4C5IRLqytpPK6k/sendPhoto");
curl_setopt($ch, CURLOPT_POST, 1);
//curl_setopt($ch, CURLOPT_POSTFIELDS,$options);
// in real life you should use something like:
curl_setopt($ch, CURLOPT_POSTFIELDS,
http_build_query($Data));
// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec ($ch);
curl_close ($ch);
// frther processing ....
if ($server_output == "OK") {
echo "ok";
}
?>

I see you want to send a picture located on a external server with its URL
so you can do as follow
define('website', 'https://api.telegram.org/bot<bot-token>');
function send($method, $datas)
{
$url = website . "/" . $method;
if (!$curld = curl_init()) {
exit;
}
curl_setopt($curld, CURLOPT_POST, true);
curl_setopt($curld, CURLOPT_POSTFIELDS, $datas);
curl_setopt($curld, CURLOPT_URL, $url);
curl_setopt($curld, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($curld);
curl_close($curld);
}
now just call this function with proper method name and data. example for sending a photo:
$postfields = array(
'chat_id' => $ChatID,
'photo' => "http://url.of/photo.jpg"
);
send("sendPhoto", $postfields);
