Getting php variables into XML?

[DavidNels]

Hey,

How can I get php variables in my page to an .XML file?

Let's say on my index.php I have a variable called $test and it's value is dynamic and changes depending on user input.

Now how can I pass $test to my xml file when I tell the page to read the xml file?

Let me know if you need any clarification. :-)

(So I could have entries in my XML like:
