MySQL Forums :: PHP :: while loop - how to remove last comma

I have a while loop that lists all manufacturers that we sell and each is seperated like this: ,  so that there is a comma and a blank space seperating each one. Is there a way to remove the comma after the last one?

Here is my script:

<?php
include 'xxxxxx.php';
$link = mysql_connect(DB_HOST, DB_USER, DB_PASS) or die("Couldn't make connection.");

//List for brands carried
$manufacturers = mysql_query("SELECT * FROM manufacturers ORDER BY manufacturers_name ASC") or die(mysql_error());
while ($rrows = mysql_fetch_array($manufacturers)) { ?>
<a href="shop/index.php?main_page=index&manufacturers_id=<?php echo $rrows['manufacturers_id']?>"><?php echo $rrows['manufacturers_name']?></a>,&nbsp;
<?php } ?>

Thanks,

Clint
