使用 PhP 从多个 MySql 表中输出数据

Question

I have 3 MySql tables:

1. "quiz" with columns 'id', 'quiz_name', 'description', 'quiz_number';
2. "questions" with columns 'id', 'question', 'question_number', 'quiz_number';
3. "answers" with columns 'id', 'answer', 'answer_letter', 'question_number', 'quiz_number'.

I want to output every quiz separately with all the questions and the answers its contents, following this structure:

Questionnaire 1

1. Question 1

   a. Answer 1 b. Answer 2 c. Answer 3 d. Answer 4 e. Answer 5

2. Question 2

   a. Answer 1 b. Answer 2 c. Answer 3 d. Answer 4 e. Answer 5

etc.

Questionnaire 2

1. Question 1

   a. Answer 1 b. Answer 2 c. Answer 3 d. Answer 4 e. Answer 5

2. Question 2

   a. Answer 1 b. Answer 2 c. Answer 3 d. Answer 4 e. Answer 5

etc.

I have tried for a few days and I can't succeed. All I got is all the answers below all the questions... I would be very grateful for any help.

Answer 1

You can do a query with all the 3 tables and information, but that's not the correct approach. Having a table with the quiz, questions and answers will have a lot of repetition and will lose the purpose.

You should query for the lists of quizes, then query que questions and do a table with all the answers.

Those are my 2 cents.
