Set $numRows to how many records you have retrieved total...
for($i=0;$i<$numRows;$i=$i+5){
echo '<tr>';
for($j=$i;$j<($i+5);$j++){
$line1='record'.$j.'Line1';
$line2='record'.$j.'Line2';
$checkbox='record'.$j.'checkbox';
echo '<td>',${$line1},'<br>',${$line2},'<br>',
${$checkbox},'</td>';
}
echo '</tr>',"\n";
}
Try it - maybe I'm just too tired, but it looks ok from here (not tested
of course)... That is assuming that you actually have the variable names
set up as you had indicated in that block of HTML...
I would be more inclined to have the SQL return 3 columns per row so I
could just use something like: $row[0], $row[1], $row[2] for the
variables...
