What I generally do is use the mod (%) operator to keep track of where
it is. It returns the remainder of the divisional operator, as such: 

0 % 4 == 0
1 % 4 == 1
2 % 4 == 2
3 % 4 == 3
4 % 4 == 0
5 % 4 == 1
6 % 4 == 2
etc...	

That way, you have a guaranteed 4-member looping variable.

Try something like this:

<?

$result = mysql_query("SELECT * FROM foo ORDER BY bar");

$count = 0;

while ($row = mysql_fetch_assoc($result)) {

	$loopcount = $count % 4;

	if ($loopcount == 0) {
		echo "<tr>\n";
	}

	echo "<td>{$row['baz']}</td>\n";

	if ($loopcount == 3) {
		echo "</tr>\n";
	}

}

?>

The only problem is that at the end of the while() loop, if you want to
have perfectly-formatted HTML, you need to figure out if it left off in
the middle of a row and fill with N empty <td></td> tags.

Also, if there's a better way to do this, I'm all ears. This is the way
I've done it for years, but it /is/ a pain to do.

Anyway, HTH!
