Answer 1

When querying you want to perform a SELECT on the table and then you can add in WHERE conditions and such. Then a mysqli_result object object will be returned. From there you can get the row with fetch_row this will return and associated array.

Now you're at the point where you need to convert the associated array to JSON, which can easily be done with json_encode.
