Question

I have a little problem, I try to make an online test but I need to shuffle answare so
1 is good answare and 2,3 bad but all time appears a = 1 b = 2 c = 3 and i want something to randomize that like a=2 b=3 c=1 how i can do that?

Code is here:

$result = mysql_query( "SELECT * FROM questions ORDER BY RAND() LIMIT 0,10");
while ($row = mysql_fetch_array($result)) {
    $rows[] = $row;
    $question_id = $row['question_id'];
    $question = $row['question'];
    $answare_good = $row['answare_good'];
    $answare_badi = $row['answare_badi'];
    $answare_badii = $row['answare_badii'];
    $number += 1;
    echo '<tr>
    <td rowspan="3" width="10">'.$number.'</td>
    <td rowspan="3" width="70%"><p>'.$question.'</p></td>
    <td width="30%" height="33%"><input type="checkbox" name="a1" id="a1">
    '.$answare_good.'</td>
    </tr>
    <tr>
    <td width="30%" height="33%"><input type="checkbox" name="a2" id="a2">
    '.$answare_badi.'</td>
    </tr>
    <tr>
    <td  width="30%" height="33%"><input type="checkbox" name="a3" id="a3">
    '.$answare_badii.'</td>
    </tr>';

I try something to array shuffle $answare_good & $answare_badi & $answare_badii but i faill.

What about this code:

$result = mysql_query("SELECT * FROM questions ORDER BY RAND() LIMIT 0,10");
while ($row = mysql_fetch_array($result)) {
    $rows[] = $row;
    $question_id = $row['question_id'];

    $answers = array(
        array('a1', 'val1', $row['answare_good']),
        array('a2', 'val2', $row['answare_badi']),
        array('a3', 'val3', $row['answare_badii']),
    );
    shuffle($answers);

    $number += 1;

    echo '<tr>
    <td rowspan="3" width="10">'.$number.'</td>
    <td rowspan="3" width="70%"><p>'.$row['question'].'</p></td></tr>';
    foreach($answers as $answer) {
        echo '<tr><td width="30%" height="33%"><input type="checkbox" name="'.$answer[0].'" id="'.$question_id.'-'.$answer[0].'" value="'.$answer[1].'" />'.$answer[2].'</td></tr>';
    }
}

You would have to specify the value for the checkbox also to be able to get the value of checked answer…

Also move to PDO or at least mysqli_* functions as mysql_* functions are deprecated now…

EDIT: Also think of using radio instead of checkbox – assuming user should pick up just one answer. If You want to let the user to pick up more than one (or all three answers), then checkbox is OK.
