Buttons defined inside php are not visible - php

Question

Neither of the divs and buttons defined after the while loop are visible until the timer goes down. I don't know what's the problem. I tried it outside the php also but still it shows nothing. Everything was working well before adding this php code to display a number of distinct questions selected from a database randomly. Someone please help me. I'm a newbie in php. Thanks a lot in advance.
<?php
$record=array(); //creating array to keep record of Q_ID of questions
for($count=1;$count <= $NoOfQuestion;$count++)// to display $NoOfQuestion number of questions
{
while(1)
{
$sql=mysql_query("select * from questions order by RAND()");
$result = mysql_fetch_array($sql);
$temp=0;
if(count($record)>=1)
{
for($i=1;$i<=$count;$i++)
{
if($record[$i]==$result['Q_ID'])
$temp++;
}
}
if($temp==0)
{
$text ='Question '.$count. '. '.$result['Question'];
echo $text;
return 0;
}
else
return 1;
}
echo'</div>';
echo'<div id="option"></div>';
echo'<div id="buton">';
echo'<input type="submit" name="Previous" value="previous" id="previous"/>';
echo'<input type="submit" name="Next" value="next" id="next"/>';
echo'<input type="submit" name="Review" value="review" id="review"/>';
echo'<input type="submit" name="Submit" value="submit" id="submit"/>';
echo'</div>';
echo'<div id="div3">3</div>';
echo'</div>';
echo'</form>';
}
?>

Answer 1

Modify your code....
echo'<div id="option"></div>';
echo'<div id="buton">';
echo'<input type="submit" name="Previous" value="previous" id="previous"/>';
echo'<input type="submit" name="Next" value="next" id="next"/>';
echo'<input type="submit" name="Review" value="review" id="review"/>';
echo'<input type="submit" name="Submit" value="submit" id="submit"/>';
echo'</div>';
echo'<div id="div3">3</div>';

Try
<?php
$record=array(); //creating array to keep record of Q_ID of questions
for($count=1;$count <= $NoOfQuestion;$count++)// to display $NoOfQuestion number of questions
{
while(1)
{
$sql=mysql_query("select * from questions order by RAND()");
$result = mysql_fetch_array($sql);
$temp=0;
if(count($record)>=1)
{
for($i=1;$i<=$count;$i++)
{
if($record[$i]==$result['Q_ID'])
$temp++;
}
}
if($temp==0)
{
$text ='Question '.$count. '. '.$result['Question'];
echo $text;
return 0;
}
else
return 1;
}
}
echo '</div>';
echo '<div id="option"></div>';
echo '<div id="buton">';
echo '<input type="submit" name="Previous" value="previous" id="previous"/>';
echo '<input type="submit" name="Next" value="next" id="next"/>';
echo '<input type="submit" name="Review" value="review" id="review"/>';
echo '<input type="submit" name="Submit" value="submit" id="submit"/>';
echo '</div>';
echo '<div id="div3">3</div>';
echo '</div>';
