PHP Telegram bot answerInlineQuery无法正常工作

Question

I'm adding inline function to my bot. I'm using PHP only. I wrote this and it seems good to me:

$content = file_get_contents("php://input");

$update = json_decode($content, true);

$inlineQuery = isset($update["inline_query"]) ? $update["inline_query"] : "";


if ($inlineQuery["query"] !== "" ) {
    $queryId = $inlineQuery["id"];
    $collection = array(
          "type" => "article",
          "id" => $queryId,
          "title" => "prov",
          "input_message_content" =>   array( "message_text" => "ciao") ,
        );

    $parameters =  array(
    "inline_query_id" => $queryId,
    "results" => $collection,
    );

    $parameters["method"] = "answerInlineQuery";

}

echo json_encode($parameters);

I get this error:

{"ok":false,"error_code":400,"description":"Bad Request: QUERY_ID_INVALID"}

What do I have to put in id? Thanks

This error usually occurs because you answer the request longer than 7-8 seconds after user type something to your inline bot. Try to answer less than 3 seconds
