This should work, but it untested. You don't need to worry about blank
entries in a table row, unless you want to try and centre them.
$file = "links.txt";
$result = file_get_contents("links.txt"); $lines = count(file("$file"));
$tdcount = 0;
$numtd = 4; // number of cells per row
echo "<table border=2>\n <tr>\n";
$arr=array($result);
foreach ($arr as $value)
{
// End of row if count mod numtd == 0, but ignore the first time round.
if ($tdcount && !($tdcount % $numtd) )
{
echo " </tr>\n <tr>";
}
echo " <td>$value</td>\n;
} // close up the table
echo " </tr>\n</table>\n";
?>
