Can i use divide in loop for PHP?

Question

Can i use divide in loop for PHP ?

I write code like that but not work.

<?PHP
    for ($k=100;$k>2;$k/2)
        {echo $k;}
?>

Answer 1

That should be $k = $k / 2, or $k /= 2.

As pointed out in the comments, you could also use a bit shift operation $k >>= 1.

Answer 2

Try with:

for ($k=100;$k>2;$k = $k/2) {
    echo $k;
}
