Answer 1

You can also process your combo box inside the while loop

<?php
//already connected yo my database

$query = mysql_query("SELECT Module_id, Module_Title FROM modules") or die (mysql_error());

//declare loop variable
$i=1;

//in while loop also you can generate the combo box try this

//selecting Module_id 
while($row=mysql_fetch_array($query))
{
  $id = $row['Module_id'];
  $title = $row['Module_Title'];

  echo"<tr><td>".$i++."</td>";
  echo "<td><select name='Module'>";
  echo "<option>-- Select Module ID --</option>";
  echo'<option value="'.$id.'">'.$id.'</option>';
  echo"</select></td>";
  echo"<td><select>";
  echo "<option>-- Select Module Title --</option>";
  echo'<option value="'.$title.'">'.$title.'</option>';
  echo"</select></td></tr>";

}


?>

In your code $id and $title are variables not array. and $number is not defined in your code so it is replacing values to these variables and u got only last value. . Please try code given below

<?php
//already connected yo my database

$query = mysql_query("SELECT Module_id, Module_Title FROM modules") or die (mysql_error());

$id = array();
$title = array();
$number = 1;

//selecting Module_id 
while($row=mysql_fetch_array($query))
{
  $id[$number] = $row['Module_id'];
  $title[$number] = $row['Module_Title'];
  $number++;

}

for($i=1; $i<=$number; $i++)        
  $idval = $id[$i];
  $titleval = $title[$i];   
  echo"<tr><td> $i</td>";
  echo "<td><select name='Module'>";
  echo "<option>-- Select Module ID --</option>";
  echo'<option value="'.$idval.'">'.$idval.'</option></td>';
  echo"</select>";
  echo"<td><select>";
  echo "<option>-- Select Module Title --</option>";
  echo'<option value="'.$titleval.'">'.$titleval.'</option></td>';
  echo"</select></tr>";
}       
?>
