Display quiz answers randomly

[mikawhat]

I'm trying to create a quiz and i can't think of a way to display the answers randomly.

  <tr>
    <td valign="middle" bgcolor="#00CCFF"><div align="center">
      <form id="form1" name="form1" method="post" action="<?php $_SERVER['PHP_SELF'] ?>">
        <input name="answer" type="hidden" value="<?php echo $answer1; ?>" />
		<a href="javascript:document.form1.submit()"><?php echo $answer1; ?></a> 
      </form>
    </div></td>
    <td valign="middle" bgcolor="#00CCFF"><div align="center">
      <form id="form1" name="form1" method="post" action="<?php $_SERVER['PHP_SELF'] ?>">
        <input name="answer" type="hidden" value="<?php echo $answer2; ?>" />
		<a href="javascript:document.form1.submit()"><?php echo $answer2; ?></a> 
      </form>
    </div></td>
  </tr>
  <tr>
    <td valign="middle" bgcolor="#00CCFF"><div align="center">
      <form id="form1" name="form1" method="post" action="<?php $_SERVER['PHP_SELF'] ?>">
        <input name="answer" type="hidden" value="<?php echo $answer3; ?>" />
		<a href="javascript:document.form1.submit()"><?php echo $answer3; ?></a> 
      </form>
    </div></td>
    <td valign="middle" bgcolor="#00CCFF"><div align="center">
	  <form id="form1" name="form1" method="post" action="<?php $_SERVER['PHP_SELF'] ?>">
	    <input name="answer" type="hidden" value="<?php echo $answer4; ?>" />
        <a href="javascript:document.form1.submit()"><?php echo $answer4; ?></a> 
      </form>
	</div></td>
  </tr>

Can anybody help me with this?

Put the answers into an array. Use shuffle() to randomize that array, then do a foreach loop on it to output your answers.

If your answers are stored in a database you could retrieve them randomly:

$i = 1;

$sql = 'SELECT answer FROM answers ORDER BY RAND()';
$result = mysql_query($sql);

while (list($answer) = mysql_fetch_row($result))
{
	echo ($i & 1) ? "<tr>\n" : '';
	echo '
	<td valign="middle" bgcolor="#00CCFF"><div align="center"> 
      <form id="form1" name="form1" method="post" action="' . $_SERVER['PHP_SELF'] . '"> 
        <input name="answer" type="hidden" value="' . $answer . '" /> 
        <a href="javascript:document.form1.submit()">' . $answer . '</a> 
      </form> 
    </div></td>';
	echo ($i & 1) ? '' : "</tr>\n";

$i++;
}
