how can i make ajax call a php file every one second using javascript?

Oh, right:

"i thought i would be cool if i make it ajax so that the script updates every one second" (sic)

What is "cool" about dragging your page to its knees?

thank you striker46 it works great just one problem the things that comeback from the boo.php is in arabic and when i get them back in ajax i get them not in arabic but in ý ýýý   how can i fix this

Let's see if I understand it well: the data retrieved from the MySQL database is stored there in arabic, but it is appears in the page as ýýýýý? Could be related with encoding...

noo when i get the data not using ajax i get it in arabic but now in ajax i get it all wrong

Can you please post the code you use to retrieve the data without AJAX?
I'll do some tests meanwhile

<meta http-equiv="Content-Type" content="text/html; charset=windows-1256" />

<?php
include 'sql.php';


$select ="SELECT * FROM posts order by id desc limit 50";
  $re = mysqli_query($mysqli,$select);

?><table width="100%"><?php
  while ($row=mysqli_fetch_array($re)){
  ?>
<tr><td><table align="right" ><tr align="right"><td><div align="right"><a href="get.php?id=<?php echo $row['id'];?>">more>></a></div></td><td  ><div align="right">
  <?php
echo $row['topic']."   ".$row['posts']." *9DJB "."   ".$row['forumid'];
?>
</div>
  <font style="font-weight:900"></td><td><div align="right"><?php echo $row['id'];?></div>
  </td>
</tr></table></td></tr>
</font><?php } ?>
</table>

  <font style="font-weight:900"></td><td><div align="right"><?php echo $row['id'];?></div>
  </td>
</tr></table></td></tr>
</font><?php } ?>
</table>

Select allOpen in new window

Try adding to the boo.php file the following line:

<?php header('Content-Type: text/html; charset=windows-1256');?>

Let's see if it helps.
