I don't know how your browser can have been published in the last few years for general use and not display this page with that "Unformatted" button where I said it is. It does not show a button outline until the pointer hovers over it, so maybe that threw you off. But it's there as rendered by MS Edge and recent Firefox browsers. It is not on the composition page, just the Threads page.
Here is some quoted code:
```
<?php
error_reporting (E_ALL ^ E_NOTICE);
include('../include/myPhpFunctions.inc');
$database="optumRx.db";
$insertVals="";
```
As Mr. Beal advised, it is enveloped by lines containing only triple-backtic. And empty lines surround the block. You can see that for yourself by clicking that "Unformatted" button. FYI, my browser's text search function finds it as the first hit.
