I’m encountering a peculiar issue while developing a Telegram bot using PHP. When I attempt to send the message ’ H’ (which includes a space before the ‘H’), it fails to deliver. The bot does not receive this message at all. Here’s the code I’ve written:
$message = ' H';
file_get_contents($url.'/sendMessage?chat_id='.$chatId.'&text='.$message);
However, when I send just ‘H’ (without any space), it works perfectly. Can anyone explain what might be causing this problem?
hey Emma, i think mac encoded chars might be an issue. Have you tried analyzing the raw requests? Sometimes spaces get lost during data transmission. Consider logging the data you’re actually sending. Also, revisit yout bot’s settings for any input restrictions. Hope it helps!
From my experience working with Telegram bots, the issue might be due to the way PHP or HTTP handles spaces in URLs. Spaces are often manipulated or removed unintentionally when constructing the URL for sending messages. You could try using url encoding for the space character. Replace the space with ‘%20’ in your message string. So, instead of sending ’ H’, send ‘%20H’ using the urlencode() function or manually replace it, and see if that works. PHP’s urlencode() function might resolve this kind of trouble swiftly. Give it a shot and observe if the issue persists.
Consider checking with different debugging tools or command line clients like curl to see how the data is being transmitted. Sometimes the command line output can reveal newline characters or erroneous spaces that are invisible in the code editor. Also, pay attention to your bot’s server configuration to ensure it correctly receives and processes the entire range of inputs, including leading spaces. Misconfigurations on the server side might affect how the data is parsed, leading to seemingly random disappearances of specific characters or formatted inputs.
