PHP method for sending images via Telegram Bot API?

Hey everyone! I’m trying to figure out how to send photos using the Telegram Bot API with PHP. I’ve read the docs about the sendPhoto command, but I’m still confused.

I tried using curl to send the image, like this:

$bot_url = "https://api.telegram.org/botMY_BOT_TOKEN/";
$url = $bot_url . "sendPhoto?chat_id=" . $chat_id;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
    "photo" => "@/my/image/path.jpg"
]);
$result = curl_exec($ch);
curl_close($ch);

But I keep getting an error about a wrong file_id. I also tried using file_get_contents instead of the file path, but that didn’t work either.

Can someone explain how to properly send a photo using PHP and curl with the Telegram Bot API? Thanks in advance for any help!

hey mate, i had similar issues. try using file_get_contents() to read the image data directly. Then pass it as a string in the POSTFIELDS. like this:

$imageData = file_get_contents(‘/path/to/image.jpg’);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
‘chat_id’ => $chat_id,
‘photo’ => $imageData
]);

this worked for me. good luck!

I encountered this issue recently and found a solution that might help. Instead of using curl directly, consider utilizing the Telegram Bot PHP SDK. It simplifies the process significantly.

First, install the SDK via Composer:

composer require telegram-bot/api

Then, you can send a photo like this:

use TelegramBot\Api\BotApi;

$bot = new BotApi('YOUR_BOT_TOKEN');
$bot->sendPhoto($chat_id, new \CURLFile('/path/to/image.jpg'));

This approach handles all the complexities of file uploads and API interactions for you. It’s more robust and less prone to errors compared to manual curl implementations. Just ensure you have the correct permissions and file path.

I’ve dealt with this exact issue before, and I can share what worked for me. The problem is likely in how you’re passing the image file to the API.

Instead of using ‘@’ before the file path, try using CURLFile. Here’s an example that should work:

$bot_url = "https://api.telegram.org/botYOUR_BOT_TOKEN/sendPhoto";
$photo = new CURLFile('/path/to/your/image.jpg');
$data = [
    'chat_id' => $chat_id,
    'photo' => $photo
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $bot_url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);
curl_close($ch);

This method has consistently worked for me. Make sure your bot has the necessary permissions and that the image file exists at the specified path. If you’re still having issues, double-check your bot token and chat_id. Hope this helps!
