A recursive function should just return an array, but this array needs 
to be assigned to the objects array variable, not as a cell in that array.

_not_ like:
$object->array[] = recursiveLoopFunction($inputdate);

but like:
$object->array = recursiveLoopFunction($inputdate);

I wouldn't say it's worth trying, it's tends to be better to do things 
the right way from the beginning. I do recommend you make classes that 
represents how your json should look like for example if you have:

{
	"order_id" : 12334,
	"total_tax": 1.10,
	"total_value": 100,
	"cart": [
		{
			"name": "item1",
			"quantity": 1,
			"price": 10
		},
		{
			"name": "item2",
			"quantity": 2,
			"price": 45
		},
	]
}

This would be two classes, the item class and the order class

class item {
	public string $name;
	public int $quantity;
	public float $price;
}

class order {
	public int $order_id;
	public float $total_tax;
	public float $total_value;
	public $cart = array();
}

here is an example code

<?php
// this is the input data we assume this is your POST data
$inputData = array("order_id" => 1234, "cart" => array( array("name" => 
"item1", "quantity" => 1, "price" => 10), array("name" => "item2", 
"quantity" => 2, "price" => 45) ) );

// this is the classes we have that describes the json
// we do init some values, just in case.
class item {
         public string $name;
         public int $quantity = 0;
         public float $price = 0.0;
}

class order {
         public int $order_id;
         public float $total_tax = 0.0;
         public float $total_value = 0.0;
         public $cart = array();
}


// here we assign the values from the post data
// without really verifying the data is okay
$order = new order();
$order->order_id = $inputData["order_id"];
$tax = 0.011; // an assumed tax % for this simplified example

// now we process the cart items
// we should take the price from a database
// instead of trusting a user
foreach($inputData["cart"] as $itemData) {
         $item = new item();
         $item->name = $itemData["name"];
         $item->quantity = $itemData["quantity"];
         $item->price = $itemData["price"];
	// we add the item to the cart array in the order object
         $order->cart[] = $item;
	// we store the totla_value in a local variable as we need it for the tax
         $total_value = $item->quantity * $item->price;
	// update the order total value/tax
         $order->total_value += $total_value;
         $order->total_tax += $tax * $total_value;
}

// the json should be the same as the one above the code, a zero missing,
// but should cause any issues as the value is equal.
echo json_encode($order, JSON_PRETTY_PRINT);
echo "\n"; // just a new line so that the prompt will come back below 
the json
?>

Don't forget that you can make functions that do parts of the moving 
data from the post data to the different objects, this way you make it 
easier to see what the code does and should make it easier to locate 
where a fault is without being distracted by code not related.
