	Nobody but you will be held responsible if something bad happens because you left customer data out in the open.
 
	USAGE: =======================================================================
	- Place this file somewhere on your server.
	- Edit the $myKey to match the key you put in your FoxyCart admin.
	- Set the $file to where you'd like the file written.
	- Save.
	- In the FoxyCart admin set the datafeed URL to the address for this script.
	- Test until you get your script working properly.
	- Remove this script from your server and disable (or change) the datafeed URL in the FoxyCart admin.
 
	REQUIREMENTS: ================================================================
