How to send a photo to telegram using php?

Question

PHP

Good afternoon!
How to send a photo (photo on the site) to telegram? I looked at the documentation, there is a sendPhoto method, but I don’t know how to apply it. You can pzhl in detail (I'm not a programming specialist). Thanks in advance!

$bot_url    = "https://api.telegram.org/$token/";
$url = $bot_url . "sendPhoto?chat_id=" . $chat_id;
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Content-Type:multipart/form-data"
));
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
    "photo"     => 'xxxxxxxxxx.ru/1544695474.png', 
)); 
curl_setopt($ch, CURLOPT_INFILESIZE, filesize('xxxxxxxxx.ru/1544695474.png'));
$output = curl_exec($ch);
print$output;
