PHP - If number is divisible by 3 and 5 then echo

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.

Answer 1

Nope... you should check first if it's divisble for 15 (3x5) (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 "";

?>

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