如何格式化Chrome Postman应用程序?

I have been sent a param called questionList. The format is like this:-

'questionList' = [{"qid":"1","ans":"798789","qst_type":"text_area"},
 {"qid":"2","ans":"1","qst_type":"radio"},
 {"qid":"3","ans":"3","qst_type":"radio"},
 {"qid":"4","ans":"789789","qst_type":"text_area"},
 {"qid":"5","ans":"like","qst_type":"like_dislike"},
 {"qid":"6","ans":4,"qst_type":"rating"},
 {"qid":"7","ans":"2","qst_type":"smiley"}]

How can I parse the results as array?

You are receiving JSON formatted string. Use json_decode($string, [$useAssoc]) to make it back to PHP array.
