How to print a variable?

When I use a while loop then my result coming like this.

$skin_type_id = '';
while ($res = $query->fetchObject()) {
    if (isset($res->skin_type_id) && $res->skin_type_id != '') {
        $skin_type_id .= $res->skin_type_id;
    }
}

Output: 471112131415174019

I want output like this:

47

11

12

13

14

15

17

40

19

so how can I do this?

while ($res = $query->fetchObject()) {
    if (isset($res->skin_type_id) && $res->skin_type_id != '') {
        echo $res->skin_type_id."<br>";
    }
}

Even this should work. you wont need an array declared for this.

Assign the values to unique array keys and then loop foreach of the indices and echo them out with a <br> tag after it, this allows you to manipulate your $skin_type_id values before outputting them.

$skin_type_id = [];
while ($res = $query->fetchObject()) {
    if (isset($res->skin_type_id) && $res->skin_type_id != '') {
        $skin_type_id[] = $res->skin_type_id;
    }
}
// do something with your $skin_type_id array which contains integers
foreach ($skin_type_id as $id)
{
    echo $id . '<br>';
}

Use <br> when you print your value.Something like this:

$skin_type_id .= $res->skin_type_id."<br>";
