我无法评论喷气机，因此：您在代码中写了一个纯文本密码并发布了！我建议您立即更改它！

对于您的原始问题：如果您想发送一条消息，则需要以下https://api.telegram.org/botYOURBOTTOKEN/sendmessage?chat_id=YOURCHATID&text=YOURMESSAGE，简要介绍您的代码，我发现有$url = "https://api.telegram.org/token";和后来的file_get_contents($url.'sendmessage?chat_id='.$data->message->chat->id."&text=".urlencode($welcometxt).".&reply_markup=".json_encode($keyboard));无法发送任何内容。从那里开始，看看情况如何，我不能保证您这是唯一的错误。

顺便说一句，您提交的代码只有49行，您提供的错误代码说第51行，所以我想您没有提交正确的作品或其他内容？
