以用户可以选择选项和导航内容的方式显示阵列内容

I am working on a Computer Base Test project where user will be tested and graded on selected subject. I have a set of questions with options in the database. I want to be able to display the question in a way the user will be able to select option and navigate the questions. I am using php/mysql.

Here is my question table structure:

question(id,subject,question,optA,optB,optC,optD,answer).

My php code is:

$query = "SELECT * from {$table} WHERE subject={$subj}";
$question_set = mysql_query($query, $connection);. 

I know I will need javascript to do this, Pls help me out.

You should send a ajax request to the server to get these data. You can use jquery AJAX for that.

$.ajax({
   url: "question.php",
   context: document.body
}).done(function(data) {
    $('#question').html(data);
});

After getting the questions from the server through AJAX request. You can display the question below the option.
