รบกวนสอบถามหน่อยคะ auto_increment ออกมาแสดงผล ได้ไหมคะ

mysql_connect("localhost","root","123456") or die("errorHOST"); 
mysql_select_db("Thai") or die ("errorDB");
mysql_query("SET NAMES UTF8");  
$arr_data= explode("|",$text);
foreach($arr_data as $val => $v)
{
  if(strlen(trim($v))>0) 
	{
   $sql = "SELECT word,frequency FROM onegram ORDER BY word_id ASC"; 
   $result = mysql_query($sql) or die(mysql_error);
?>
    <table  border="1" >
	<tr> 
    <th>word_id</th> 
    <th>word</th>
    <th>frequency</th>
    </tr>
<?
    while($dbarr = mysql_fetch_array($result))
    {
?>
    <tr><center>
    <td><div align="center"><? echo $dbarr  ['word_id']; ?>  </td>
    <td><? echo $dbarr  ['word']; ?>     </td> 
    <td><div align="center"><? echo $dbarr  ['frequency']; ?></td>
	
    </certer></tr>
 <?  }
?>
</table>
