With the next code i can change numbers with images (i dont want google know this telephone numbers). It's possible insert blank spaces each 3 numbers/images?

For example, the phone is 111222333 and i want show 111 222 333 in front.

```
<?php global $wp_query; 
$postid = $wp_query->post->ID; 
$i=intval(get_post_meta($postid, 'telefono_2', true));
$s='';
while($i>0)
    {
    $digit=$i % 10;
    $i=(int)($i/10);
    $s="<img style='vertical-align:middle;' src='http://localhost/buscatuescort/wp-content/themes/Avada/images/$digit.png' width='12' height='18' />$s";
    }
echo $s ?>

```
