SAVING RECORD

I am a newbie in FLEX and PHP. I am creating a quiz application with Flex and PHP. Now what I want there should be SAVE button. When user clicks on SAVE button then suppose User had completed only 5 questions among 50 questions then also it will save the 5 answers. I know how to send data to PHP using HTTPSERVICE. But all those are single single data; not bunch of data. So my question is :

1. what will be the best procedure to hold those data primarily ?
2. How can I send those data to PHP ?
3. In PHP how can i parse those data and save it in database ?

Any answer in this regard will be highly appreciable ......
