PHP: Assign array to variable - php

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 showed me here that this works so i must be doing it wrong somewhere else.
I'll explan the whole code:
To login to my webpage, i send a request trough AJAX request with 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" and "attr" are encrypted values that i send to reference some actions on the system (i'll show more here):
The code goes from AJAX to SendRequest.php where it executes an action let's say, login.
The first lines of SendRequest.php are:
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, $finalPost);
Then, this is what i want to achieve to communicate with my API:
function APICall($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 $toApiData;
}
This is what i have on API side:
ob_start();
var_dump($_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;
}
This ALWAYS returns
array(2) { ["uData"]=> string(5) "Array" ["uPost"]=> string(5) "Array" }
I hope im more clear now, thanks.

The problem is with the request being sent out from your code because of this line:
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
CURLOPT_POSTFIELDS doesn't support multi-level arrays. Your array values (which the keys are pointing to) are cast to string, which ends up as Array. Use:
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
.. instead to "properly" serialize multidimensional arrays in a post request ("properly" as there are many ways to do just that, but it matches the expected PHP format - with [] to denote arrays).
