PHP表：不能被3整除的数组不显示最后一行

Question

I'm trying to split my array into 3 columns and the remaining that is not divisible by 3 to show as well. Currently it's not displaying. My code as below:

Count value is 8.

for($i=0; $i < count($subscriber); $i++) {

    if($i%3==0) $middle_data .= '<tr>';

    <td>Array fields goes here</td>

    if(($i+1)%3==0) $middle_data .= '</tr>';
}

Currently it shows 2 row but the last row that is not divisible by 3 is not appearing.

Answer 1

Your code echoing all values, but produce invalid markup. It looks like

<table>
<tr><td></td><td></td><td></td></tr>
<tr><td></td><td></td><td></td></tr>
<tr><td></td><td></td>
</table>

Try this one

$subscriber = array_fill(0, 8, 'value');
$count_column = 3;

// loop by cells count, not values count
$count_cell = ceil(count($subscriber) / $count_column) * $count_column;

$middle_data = "<table>
";
for ($i = 0; $i < $count_cell; $i++)
    {
    if ($i % $count_column == 0)
        $middle_data .= '<tr>';

    if (isset($subscriber[$i]))
        $middle_data .= '<td>' . $subscriber[$i] . '</td>';
    else
        $middle_data .= '<td></td>';

    if (($i + 1) % $count_column == 0)
        $middle_data .= "</tr>
";
    }
$middle_data .= "</table>
";
echo $middle_data;
