Act as an expert PHP Backend Developer. I have a custom PHP routing architecture and I need to integrate a new Payment Gateway.

I will provide the API documentation for the gateway's "Create Order" and "Webhook/Callback". Based on the documentation, you need to generate TWO PHP files:
1. `order/[gatewayname].php` (To create the payment link)
2. `webhook/[gatewayname].php` (To handle callbacks and update my Next.js backend)

### 📌 System Context & Available Config:
I have a `lib/config.php` file that contains:
- `DOMAIN` (e.g., 'http://localhost/MyApps/p2pxgetway')
- `UPDATE_STATUS_DOMAIN` (e.g., 'http://localhost:3000')
- A logging function: `log_api_data($title, $data, $filename)`

### 🛠️ File 1: `order/[gatewayname].php` Requirements:
1. Add strict CORS headers allowing POST requests from all origins (`*`).
2. Read JSON input `php://input` expecting `order_id` and `amount`.
3. Require `../lib/config.php`.
4. Apply the exact Signature/Hash generation logic as mentioned in the gateway documentation.
5. Send the `callback_url` as: `DOMAIN . '/webhook/[gatewayname].php'`.
6. Use cURL to POST the data to the Gateway's Create Order endpoint.
7. **Logging:** Use `log_api_data()` to log the Request Payload, cURL errors, Gateway Rejection Errors, API Down Errors, and the Gateway Success Response. Save logs in `[gatewayname]_order` and `[gatewayname]_error`.
8. Return a JSON response for the frontend in this exact format on success: `{"payment_url": "https://..."}`.

### 🛠️ File 2: `webhook/[gatewayname].php` Requirements:
1. Set `Content-Type: application/json` header.
2. Require `../lib/config.php`.
3. Read the incoming webhook payload (JSON or form-data based on docs).
4. **Logging:** Immediately log the incoming webhook data using `log_api_data()`.
5. Extract the merchant order ID and the payment status (`success`, `failed`, etc.) from the payload as per the gateway's response structure.
6. Create an update payload: `{"action": "update", "payload": {"id": merchantOrderId, "status": parsedStatus}}`
7. Use cURL to POST this update payload to my Next.js API. 
   **Strictly use this URL:** 
   `$nextJsApiUrl = UPDATE_STATUS_DOMAIN . '/admin/api/update-buy-order';`
8. Log the response received from the Next.js API.
9. Output the exact HTTP Status Code and JSON format expected by the Payment Gateway's callback documentation (e.g., `{"status": "ok"}` with a `200 OK` header).
