Transfer counter variable from PHP to .JS file

I'm trying to pass a counter variable that I made in my PHP script to my .JS file. I've read on here that the best way to do this is with JSON (I'm writing with JQuery), but I'm having a hard time getting it to work with what I have.

In my PHP, I apply my counter to a td class and then send it over via JSON. So:

….
<table>
<?php $counter = 0;?>
<?php while ($counter < 20) : ?>
<tr>
...
<td class="classname<?php echo $counter; ?>"></td>
</tr>

<script type="text/javascript">
var counter = <?php echo json_encode($counter); ?>;
</script>

<?php $counter++;
endwhile; ?>
</table>
…

Now in my .js file, I have the following line that tries to put the counter that I echoed into the CSS identifier:

  if...
  $('td.classname' + counter).text("Text gets displayed");/* Change text in td */}

Is this the wrong way to access the variable?

No need of JSON since you are doing this on server side, just remove json_encode and echo the value which will assign it to js counter. 

<script type="text/javascript">
var counter = <?php echo $counter; ?>;
</script>
