I making a small cron job which basically crawl questions and answers from Stack.

Here is my request URL : https://api.stackexchange.com/2.2/questions?order=desc&tagged=php&site=stackoverflow&filter=withbody&no_expiry=true&pagesize=100&key=[my_app_key]access_token=[my_acc_token]

It returns 100 latest questions in PHP tag perfectly. But I would like to include the answers of the questions too (if it is answered). I have checked the filters section of documentation but I didn't get it exactly. Can anyone point me to correct direction ?
