PHP Telegram Bot: Custom Keyboard with Reply Markup Issue

Other Questions Telegram bot
1

I am developing a Telegram bot using PHP and I need help configuring a custom keyboard through the reply_markup option. My current implementation does not produce the intended interface, and I am looking for advice on how to correct this issue. I want to properly display an interactive keyboard to the user by adjusting my code accordingly. Below is a revised code snippet that I am currently trying:

$botEndpoint = $apiBase . '/sendMessage';
$targetChat = $userChatID;
$messageText = 'Button Sample';
$keyboardSetup = json_encode([
    'keyboard' => [[ 'Option A', 'Option B' ]] 
]);

$constructedUrl = $botEndpoint . '?chat_id=' . $targetChat . '&text=' . urlencode($messageText) . '&reply_markup=' . $keyboardSetup;
$output = file_get_contents($constructedUrl);
echo $output;

Any guidance or modifications that could make the custom keyboard function correctly would be greatly appreciated.

I have been working on similar projects and found that determining the correct API endpoint issues is critical. In one of my previous projects, ensuring that the reply_markup parameter was correctly URL encoded made a significant difference. I also discovered that sometimes the Telegram API may require additional parameters like parse_mode and disable_web_page_preview for a smooth interface performance. Checking for potential PHP warnings or misconfigurations on the server side helped me resolve similar issues, so it’s worth verifying the response from Telegram for any clues.

In my experience working with Telegram bots through PHP, I discovered that the key to solving custom keyboard issues is ensuring that the reply_markup parameter is properly encoded and transmitted. I ran into a scenario where the JSON structure was technically correct but still failed due to subtle issues with file_get_contents not handling errors well. Switching to cURL not only provided better error handling but also revealed additional server-side logs that pointed out misconfigurations. Additionally, verifying that the API returns a valid response can be very informative during debugging.

hey, i’ve been in a similar spot. try encoding the json fully or switching to curl for clearer error messages. sometimes file_get_contents doesnt catch subtle encoding errors that mess the keybord display.

After encountering similar issues in my own Telegram bot implementation, I realized that sometimes the problem may not reside entirely in the PHP code but in the way the Telegram server processes the JSON data. I adjusted my code to not only fully encode the reply_markup parameter but also ensure that my server’s error reporting was appropriately set up to capture any issues. Adding error handling and checking the responses thoroughly helped me isolate subtle JSON formatting issues. A switch to cURL also revealed necessary debug information that file_get_contents was missing, ultimately leading to a proper solution.
