Php 如何在电报中应答回拨查询后发送消息？

我正试图用PHP开发一个电报机器人，但当用户按下内联按钮时，我没能让我的机器人回答用户。
在调用

answerCallback

方法后，有人能帮我发送消息（

sendMessage

方法）吗

这是我最后的试用代码：

if ($call_back_query != null) {
    
    $response = $call_back_query;
    $botUrl = "https://api.telegram.org/bot" . BOT_TOKEN . "/answerCallbackQuery";
    $postFields = array('callback_query_id' =>  $call_back_id, 'text' => $response);
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type:multipart/form-data"));
    curl_setopt($ch, CURLOPT_URL, $botUrl); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
    $output = curl_exec($ch);
    
    //send Text
    $response = "help me if you can, i'm feeling down";
    header("Content-Type: application/json");
    $parameters = array('chat_id' => $chatId, "text" => $response);
    $parameters["method"] = "sendMessage";
    echo json_encode($parameters);                
  }

---

好的，我已经理解了这个问题：

在

sendText

中，我必须使用

$call\u back\u from

而不是

$chatId

，因为他回答的是回调查询，而不是简单的消息（我想是这样的…）

当

$chatId=isset（$message['chat']['id']）$消息['chat']['id']：“”

$call\u back\u from=isset（$update['callback\u query']['from']['id']）$更新['callback_query']['from']['id']：''

代码将是

if ($call_back_query != null) {  
    $response = $call_back_query;
    $botUrl = "https://api.telegram.org/bot" . BOT_TOKEN . "/answerCallbackQuery";
    $postFields = array('callback_query_id' =>  $call_back_id, 'text' => $response);
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type:multipart/form-data"));
    curl_setopt($ch, CURLOPT_URL, $botUrl); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
    $output = curl_exec($ch);

    //send Text
    $response = "help me if you can, i'm feeling down";
    header("Content-Type: application/json");
    $parameters = array('chat_id' => $call_back_from, "text" => $response);
    $parameters["method"] = "sendMessage";
    echo json_encode($parameters);        
}

希望这能有所帮助！
