Do you want to convert numbers into words try the following code

convert_number_to_words.php

<?php 
function convert_number_to_words($number) {

    $hyphen      = '-';
    $conjunction = ' and ';
    $separator   = ', ';

    $decimal     = ' point ';
    $dictionary  = array(
        0                   => 'zero',
