eBay-API, getItem and AddItem-Function needed

Hi Coders, I need a small Script, that just has 2 functions, which I need to run from my other PHP-Scripts. 1 Function: getItem-Call. I need to call this function like this: get_item($itemID), where $itemID is the eBay-Auction-ID. Then the function must reed ALL needed Datas, to relist this Item later. So, it should read Item-Title, Startprice,Listingduration, Auctiontype, Shippingdetails and all this Stuff, including Country and categoryspecifics Informations(!) and store this Datas to an MySql-DB. 2 Function: AddItem-Call. I need to call this function like this: get_item($auctionID), where $auctionID is the Database-ID of the prevously safed Item-Datas from the getItem-Call. If I run this function, it should add an new Item on eBay with all these Datas, wich are stored in the Database. So, this Call should add an 100% Copy of the first Item. I need everything, to make this Script working and the Script, but nothing else. So, NO Userinterface or something like this. If I can run call this functions from my Scripts, its fine.
