Using PHP, I’m fetching my Telegram bot details but can’t extract the username from the JSON response.

$apiEndpoint = "https://api.telegram.org/botMY_TOKEN/fetchInfo";
$responseStr = file_get_contents($apiEndpoint);
$resultData = json_decode($responseStr, true);
$botUsername = $resultData['result']['username'];

I dealt with a similar issue and found that adding error checks really helped avoid problems when the JSON response wasn’t structured as expected. Instead of directly accessing the username key, I implemented checks to ensure that both the top level ‘result’ and the ‘username’ keys exist, which prevented undefined index errors. Additionally, I switched from file_get_contents to using cURL for better error handling and debugging, especially when working with network timeouts or invalid tokens. Validating the response structure can really simplify troubleshooting.

hey, try checking if the username key exists before accessing it. i’ve had issues when the json structure isnt always consistent. a simple isset($result[‘result’][‘username’]) can help avoid errors when the api replies differently.
