### PHP cURL example for creating plan version by external ID

Source: https://docs.withorb.com/api-reference/plan/create-plan-version-by-external-id

Uses PHP cURL to POST to the same endpoint. The request body is not shown in this snippet, but the setup includes the URL, method, and headers. The example is incomplete as the body is missing.

```php
<?php

$curl = curl_init();

curl_setopt_array($curl, [
  CURLOPT_URL => "https://api.withorb.com/v1/plans/external_plan_id/{external_plan_id}/versions",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
```
