Mainly do single-choice and multiple-choice questions! I put the questions, options and correct answers into the same database, three questions! !
Can I design the option as a field and store it in json? Are the answers stored in another field?
When the user answers the question, I return all the questions, options and answers. When the user selects the answer, how should I judge whether the answer selected by the user is correct? Or do we need to request the database for the answer?

1. Doesn’t it taste good with implode? Why use json? 2. Re-visit the database to determine whether it is right or wrong.
