iOS iOS to PHP to XML

[newtoiphonesdk]

I have an XML that is set up on my server on Yahoo. I am working on building a PHP script that will append the XML with a new item tag, along with all of the child nodes within that item. However, I am confused with how to set up the PHP to use placeholders for each of those, and then how to pass data into those placeholders from the iOS app. I would love a tutorial or some guidance in this. Thanks

This is too abstract for me to follow... Can you give an actual example of input and output you want?
