Hi I need to convert the natural output from a range to a list of numbers separated with commas and exclude some output numbers

```
foreach (range(0, $clpyrdesde, 2) as $numero) {
    echo $numero;
}

```

If $clepydesde was "18" the output was "024681012141618" I need this numbers like "0,2,4,6..." and excluding the "0", so results needs to be "2,4,6..."
