PHP Calls Using [RAW]

I’m trying to get this to work in order to (1) define a PHP variable and (2) echo that variable with another PHP script into a chunk of text on a WooCommerce Single-Product page.

Here’s what I’m doing – I’ve put the following on the page via the Text/HTML editor:

[raw]
<?php global $state = "California";?>
 
<?php include '../php/info-section.php';?>
[/raw]

When I update the product page, the two PHP lines … disappear! In the text editor, it shows:

[raw]
 
[/raw]

I’m guessing one of two things are happening: either the Raw HTML plugin doesn’t allow PHP calls, or I’m setting it up wrong.

The PHP works – I’ve tried it on a standard HTML/PHP page, but it does not work on a WooCommerce product page.

Any suggestions would be appreciated!
