Please have a look at substr based function that can change formats

{
    $FORMAT_PHONE = [1,3,3,4];
    $result =[];
    $position = 0;
    foreach ($FORMAT_PHONE as $key => $item){
        $result[] = substr($in, $position, $item);
        $position += $item;
    }
    return '+'.implode('-',$result);
}
