PHP: End and start a new <tr> after 6 rows - php

Question

I want to make a table, and then for each 6 rows should have a tr, and then the rows are inside td.
So example:
<tr>
<td><?php echo $show[id]; ?></td> // 1
<td><?php echo $show[id]; ?></td> // 2
<td><?php echo $show[id]; ?></td> // 3
<td><?php echo $show[id]; ?></td> // 4
<td><?php echo $show[id]; ?></td> // 5
<td><?php echo $show[id]; ?></td> // 6
</tr> <tr> // start new tr after 6 rows
...repeat the tds
How can i do something like this?
I have tried myself doing
<tr>
<?php
while ($show == mysql_fetch_array($query)){ ?>
<td><?php echo $show[id]; ?></td>
<?php } ?>
</tr>
But as you can see this just inserts everything in one tr..
Thank you

Answer 1

<tr>
<?php
$c = 0; // Our counter
$n = 6; // Each Nth iteration would be a new table row
while ($show = mysql_fetch_array($query))
{
if($c % $n == 0 && $c != 0) // If $c is divisible by $n...
{
// New table row
echo '</tr><tr>';
}
$c++;
?>
<td><?php echo $show[id]; ?></td>
<?php
} ?>
</tr>

Answer 2

Count the number of lines if the modulo 6 is null then echo the </tr><tr>
<tr>
<?php
$i=0;
while ($show == mysql_fetch_array($query)){ ?>
<td><?php echo $show[id]; ?></td>
<?php if(++$i%6 == 0) echo '</tr><tr>'; ?>
<?php } ?>
</tr>

Answer 3

You can do:
<tr>
<?php
$count = 0;
while ($show = mysql_fetch_array($query)){
if($count == 6) {
$count = 0;
echo "</tr> <tr>";
}
echo "<td>".$show[id]."</td>";
$count++;
}
</tr>

Answer 4

You’re accidentally using the comparison operator == instead of an assignment operator =.
And to always put six cells into each row, I’d do this:
$perRow = 6;
$counter = 0;
echo '<tr>';
while ($show = mysql_fetch_array($query)) {
if ($counter % $perRow === 0 && $counter !== 0) {
echo '</tr><tr>';
}
echo '<td>', $show['id'], '</td>';
$counter++;
}
while ($counter++ % $perRow !== 0) {
echo '<td></td>';
}
echo '</tr>';
This will ensure that each row is properly filled with six cells.

<?php
$countRows = 0;
while ($show == mysql_fetch_array($query)){
if($countRows == 0) echo '<tr>';
?>
<td><?php echo $show[id]; ?></td>
<?php
$countRows++;
if($countRows == 6){
$countRows = 0;
echo '</tr>';
}
?>
<?php } ?>
<?php if($countRows < 6) echo '</tr>'; ?>
