PHP：将数组赋值给变量

Question

i've tried a lot of things to achieve this but none of them seem to work. Im using PHP 7.4

Let's say i have this:
$othervar = array();
$var = array(1, 2, 3);
$othervar = $var;
THIS doesn't work for me, var_dump($othervar) returns
array(1) { [0]=> string(5) "Array" }
I've tried using array_push, i DON'T WANT to use array_merge because i need to assign two arrays to one variable. This is what i need to do:
$variable = array();
$variable["type1"] = $data; //Array 1
$variable["type2"] = $otherData; //Array 2
This doesn't work either.

Barmar 向我展示了 here 这行得通，所以我一定是在其他地方做错了。

我将解释整个代码：

要登录到我的网页，我通过 AJAX 请求发送请求 jQuery。

function SendData(data, btn, actionOnSuccess, shouldReplace = false, elementToReplace = "", getServerData = true, htmlData = "") {
    if (!loading)
    {
        ToggleLoading();
        data.push({name: "action", value: $(btn).data("action")});
        data.push({name: "attr", value: JSON.stringify($(btn).data("attr"))});
        $.post("SendRequest.php", data)
            .done(function (r) {
                if (!r.success)
                    //ajax sent and received but it has an error
                else
                    //ajax sent and it was successfull
            })
            .fail(function () {
                //ajax call failed
            });
    }
    else {
        //This determines if some request is already executing or not.
    }
}

"action" 和 "attr" 是我发送的加密值，用于引用系统上的某些操作（我将在此处显示更多信息）：

代码从 AJAX 到 SendRequest.php 执行一个操作，比如登录。

SendRequest.php的第一行是：

    require "Functions.php";

    $apiAction = Decrypt($_POST["action"]); //Action
    $actionData = json_decode(Decrypt($_POST["attr"])); //Attr
    $finalPost = $_POST;
    foreach ($actionData as $key => $value) { $finalPost[$key] = $value; }

    $finalPost["loggedin_ip"] = $_SERVER['REMOTE_ADDR'];
    $result = APICall($apiAction, $finalPost);

那么，这就是我想要与 API 进行通信的目的：

function APICall($option, $data = array())
{
    session_start();
    $post = array("uData" => ArrayToAPI($_SESSION), "uPost" => ArrayToAPI($data));

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    curl_setopt($ch, CURLOPT_URL, "https://apiurl?" . $option); //option is the ACTION to perform on API (let's say "login") it is an encrypted word on a data-attr atribute on every form/button that creates a communication with API.
    $returned = curl_exec($ch);
    curl_close ($ch);
    $newData = json_decode($returned, true);
    return $newData;
}

function ArrayToAPI($array)
{
    $toApiData = array();
    foreach ($array as $key=>$value) {
        if (is_array($value))
            $toApiData[$key] = ArrayToAPI($value);
        else
            $toApiData[$key] = Encrypt($value);
    }
    return $toApiData;
}

这就是我在 API 方面的情况：

ob_start();
var_dump($_POST);
$result = ob_get_clean();
$api->EndRequest(false, array("errorDesc" => "a - " . $result));

function EndRequest(bool $task_completed, array $data = array())
{
    $jsonData = array();
    $jsonData['success'] = $task_completed;
    $jsonData['data'] = $data;
    header('Content-type: application/json; charset=utf-8');
    echo json_encode($jsonData, JSON_FORCE_OBJECT);
    exit;
}

这总是 returns

array(2) { ["uData"]=> string(5) "Array" ["uPost"]=> string(5) "Array" }

我希望我现在更清楚了，谢谢。

Answer 1

问题在于从您的代码发出请求是因为这一行：

curl_setopt($ch, CURLOPT_POSTFIELDS, $post);

CURLOPT_POSTFIELDS 不支持多级数组。您的数组值（键所指向的）被转换为字符串，最终为 Array。使用：

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));

.. 而不是 "properly" 在 post 请求中序列化多维数组（"properly" 因为有很多方法可以做到这一点，但它符合预期 PHP 格式 - [] 表示数组）。
