This works simple and simple using recursion

function getExcelCol($num) {
    $numero = $num % 26;
    $letra = chr(65 + $numero);
    $num2 = intval($num / 26);
    if ($num2 > 0) {
        return getExcelCol($num2 - 1) . $letra;
    } else {
        return $letra;
    }
}

you do not have to worry about this anymore, PHP does what you want it to do

    <?php
        $miletra = "A";
        for ($i =0; $i < 30; $i++){
            echo $miletra."<br/>";
            $miletra++;
        }
?>
