將鍵值附加到PHP中的關聯數組

Question

我有一個數組：

$data["messages"][] = array("chatId" => $chat_id, "type" => "text", "to" => $username, "body" => "success");

當print_r數組時，它看起來像這樣：

Array ( [messages] => Array ( [0] => Array ( [chatId] => d3a611401de00e8c8b3e225a7cf95484033f57ea18c442249ee9b5bcb63c9a96 [type] => text [to] => pitashi [body] => success ) ) )

但是，當我嘗試將新的鍵值附加到末尾時，如下所示：

$arr_keyboards[] = array(
    "type" => "suggested",
    "responses" => array(
    array("type" => "text", "body" => "Yes"), 
        array("type" => "text", "body" => "No")
        )

);

$data["messages"]["keyboards"] = $arr_keyboards;

我最終得出以下結論：

Array ( [messages] => Array ( [0] => Array ( [chatId] => d3a611401de00e8c8b3e225a7cf95484033f57ea18c442249ee9b5bcb63c9a96 [type] => text [to] => pitashi [body] => success ) [keyboards] => Array ( [0] => Array ( [type] => suggested [responses] => Array ( [0] => Array ( [type] => text [body] => Yes ) [1] => Array ( [type] => text [body] => No ) ) ) ) ) )

注意新的鍵值“ keyboards” => array（...在上一個數組關閉后被添加。我希望它看起來像是：

Array ( [messages] => Array ( [0] => Array ( [chatId] => d3a611401de00e8c8b3e225a7cf95484033f57ea18c442249ee9b5bcb63c9a96 [type] => text [to] => pitashi [body] => success [keyboards] => Array ( [0] => Array ( [type] => suggested [responses] => Array ( [0] => Array ( [type] => text [body] => Yes ) [1] => Array ( [type] => text [body] => No ) ) ) ) ) 

最后，我對它進行json編碼。 這是它的外觀屏幕截圖，以及我需要在哪里使用的屏幕截圖https://www.evernote.com/l/AETNv5OhBI1HtLzqXalq-BCfOIwz4U0jlWw ，這是最終我希望它的外觀屏幕截圖https：//www.evernote .com / l / AETRjOREKvBHLpXyh3NdZdGAryyxO2rIiwg

我很笨 謝謝您的幫助。

Answer 1

嘗試這個：

$data["messages"][] = array(
    "chatId"    => $chat_id, 
    "type"      => "text", 
    "to"        => $username, 
    "body"      => "success"
);

$arr_keyboards = array(
    "type" => "suggested",
    "responses" => array(
        array("type" => "text", "body" => "Yes"), 
        array("type" => "text", "body" => "No")
    )
);

foreach ($data["messages"] as $message) {

    $message["keyboards"] = $arr_keyboards;
}

echo json_encode($message);

希望這可以幫助。

Answer 2

您試圖將$arr_keyboards數組添加到$data["messages"]數組的第一個元素中。
更改“ 關鍵 ”代碼行，如下所示：

$data["messages"][0]["keyboards"] = $arr_keyboards;
