cart database example item items php position script separate sql utilize utilized

Hello,

I am trying to figure out how to use item_cart_position in a php script. Im not sure how it works and how to utilize it to separate items so I can place them into a sql database. Does anyone have an example php script which shows how it can be utilized?

thanks
