Basic capture script for a begginer

[will108]

Hi guys,
I have just started (trying) to learn php.
I though I would start small.
I need to record data from a box.
The box is outputting a XML file and can hit a URL.
I understand that I need my php script to be that URL.
I only need the php script to record and save the 1 field in the box.
It can save it to anything, .txt, .csv, .xml, i don't mind.
I don't need the php to check the document before it writes to it.

Can anyone supply me with a very basic, 'write to .csv' php script please?
I have looked around, but all the scripts are way too advanced.

Thanks in advance guys.
Will.
