Question

I’m new to PHP and trying to create the following whilst minimizing the amount of code needed. PHP should show a list of 100 then display if the number is / by 3, 5 or 3 and 5. If not by any then show nothing.

This is what I’ve got so far, but any help would be great since not sure about the / by 3 and 5 bit as you can see below.

<?php $var = range(0, 100); ?>
  <table>
<?php foreach ($var as &$number) {
 echo " <tr>
    <td>$number</td>
    <td>";

    if($number % 3 == 0)  {
    echo "BY3";
} elseif ($number % 5 == 0) {
    echo "BY5";
} elseif ($number % 3 and 5 == 0) {
        echo "BY3 AND 5";
}
 echo "</td></tr>";
}
?>

  </table>

Thanks

Nope… you should check first if it’s divisble for 15 (3×5) (or 3 and 5) and after you can do other checks:

if($number % 15 == 0)  {
    echo "BY3 AND 5";
} elseif ($number % 5 == 0) {
    echo "BY5";
} elseif ($number % 3 == 0) {
    echo "BY3";
}
 echo "</td></tr>";

?>

Because every number divisble for 15 is also divisble for 3 and 5. So your last check could never hit
