PhP variables added to XML

[mavedog21]

Hi, first post here. Hope somebody can guide me.

History of question:
I'm working in Flash 8 pro and have an XML file I read from.
I want to be able to create an form that can create/add to my xml file from php variables declared in a flash application. I was told php might be able to help me.

Question:
Can you save php variables into an xml file on the server and if so, can they be saved in a certain order? If so, can somebody point me in the direction of a tutorial that may help?

Psuedo Example:

In Flash 8:
var: name = tom;

In PHP:
$firstName= $var.name;

Php variable then added to and saved in XML:
<person>
<firstName> tom</firstName>
// so variable <firstName> is always saved as childNodes [i][0]
</person>


Is this possible?
