Modulus division operator, with offset?

I have a loop:

foreach ($arr as $_k => $_v) {
    if($_k % 6 == 0){

        //do something
    }
}

I need "something" to happen every sixth loop, but I need an offset of 2. So it would happen in loop 2, 8, 14 etc.

How can this be achieved?

Furthermore, I also need the "something" to happen on offsets of 4 too. So 4, 10, 16 etc.

Is this possible in the same operator or would I need an or statement?

Simple enough

$_k % 6 == 2

Or more generally

$_k % 6 == offset

For your case if you need to do something different at offset 2 and 4, you will need to do two if statements.

if ($_k % 6 == 2)
{
 ...
} else if ($_k % 6 == 4)
{
 ...
}

Just change the comparison.

if ($_k % 6 == 2) {
   ...
}

if ($_k % 6 == 4) {
   ...
}
