I'm a little unclear as to what you're trying to do, but here's my
interpretation:
problem 2: if it ends on a complete row...
solution: put the echoing of the first and last tr's inside your
conditional. When $x is initialized to 0, the if will return true, and you
will output the very first tr...same at the end...so i'd have something like
this:
<table width="450" border="1" align="center">
<!-- we delete this first <tr> //-->
<?
$x = 0;
#different here for later reason
$length = 42;
while ($x <= $length)
{
$x++;
if ($x % 5 == 0)
{
echo "<tr>\n";
}
echo "<td>".$x."</td>\n";
if ($x % 5 == 0)
{
echo "</tr>\n";
}
}
#also added in
if($length % 5 != 0){
{
#then we know that it did not end completely, so echo you're final </tr>
echo "</TR>\n";
}
#no need for an else block because it would do nothing
?>
<!-- as well as this one </tr> //-->
</table>
Now if it ends on a complete row, you're fine!
problem 1: what about if it ends at 42 or something, with just a closing
</td>?
solution: make a final check to see if you need that closing </tr>
That is the if statement after you're loop...
I hope this helps.

Subject: [PHP] cell iterations in loop
I've got some code that I am
creating that creates a table with
a loop. and it works fine for what
it is, but my question is how do I
compensate for rows that aren't divisible
by 5 ? i.e. the empty cells at the table.
additionally if it ends on a complete row
(divisible by 5) I end up with an additional
empty row at the end of the table, I can
see why it does, I'm just trying to get around
it. no big hurry on this, I'm just trying to
learn more.

<table width="450" border="1" align="center">
<tr>
<?
$x = 0;
while ($x <= 42)
{
$x++;
if ($x % 5 == 0)
{
echo "<td>".$x."</td>\n";
echo "</tr>\n<tr>\n";
}
else
{
echo "<td>".$x."</td>\n";
}
}
?>
</tr>
</table>
