通过一个数组循环，每个第6个元素换行作为一个表？

Question

I am trying to print an array so every 6th element is on a new line. I'm trying to do this in a table. I would prefer if it could be answered in PHP, but Javascripts Ok.

$array_control = array(
"1","5","6","2","1",
"2","1","6","4","3",
"3","2","5","6","6",
"4","3","1","5","4",
"6","4","2","3","6"
);
$arrayLength = count($array_control);

    $i = 0;

    while ($i < $arrayLength)
    {
        if ($i==0) {
            echo "<tr>";
        }
       if (is_int($i/5)) {
         echo '<td style="width:16%;">'.$array_control[$i].'</td>';
         echo "</tr>";
            echo "<tr>";

        }else{
             echo '<td style="width:16%;">'.$array_control[$i-1].'</td>';

        }

        $i++;


    }

Any help would be great!

The %-operator (modulus) solves this for you:

echo '<table><tr>';
for($i = 1; $i <= count($array_control); $i++ ){
    echo '<td style="width:16%;">';
    if( ($i % 6) == 0){
        echo $array_control[$i-1] . '</td></tr><tr>';  
    } else{
        echo $array_control[$i-1] . '</td>';
    }
}
echo '</tr></table>';

or if you feel sassy:

echo '<table><tr>';
for($i = 1; $i <= count($array_control); $i++ ){
    echo '<td style="width:16%;">' . $array_control[$i-1], ( ($i % 6) == 0 ) ? '</td></tr><tr>' : '</td>';
}
echo '</tr></table>';
