[php] Convert utf8-characters to iso-88591 and back in PHP

I use this function:

function formatcell($data, $num, $fill=" ") {
    $data = trim($data);
    $data=str_replace(chr(13),' ',$data);
    $data=str_replace(chr(10),' ',$data);
    // translate UTF8 to English characters
    $data = iconv('UTF-8', 'ASCII//TRANSLIT', $data);
    $data = preg_replace("/[\'\"\^\~\`]/i", '', $data);


    // fill it up with spaces
    for ($i = strlen($data); $i < $num; $i++) {
        $data .= $fill;
    }
    // limit string to num characters
   $data = substr($data, 0, $num);

    return $data;
}


echo formatcell("YES UTF8 String Zürich", 25, 'x'); //YES UTF8 String Zürichxxx
echo formatcell("NON UTF8 String Zurich", 25, 'x'); //NON UTF8 String Zurichxxx
