Have you tried this:

function format_string($string) {
    // format the string...
    $result = string;
    if (isset($this)) $this->elements[] = $result;
    return $result;
}

In this form you can check the existance of $this. If you call the 
method statically then $this is not present and the elements array is 
not filled. If you call it non-statically then $this is present and 
elements is filled. The same you can do with show_all().
