Easily convert Numbers into Words in PHP

Sometimes we need to convert numbers into words or texts in PHP application. But PHP don’t have build in functions to convert numbers into words.

Especially, sometimes we want to display currency in words. For eg. if we convert number 15,070 into words it will be Fifteen Thousands Seventy. But how can we achieve this conversion in a simple PHP way.

Well, I have a simple solution for that. I’ve made a simple PHP function for converting numbers into words. You can use to convert any type of numbers such as currency, distance, measurements etc.

Just change $numbers_name and $decimal_name variable according to your requirements.

<?php 
function NumbersToWords(float $number)
{
    // change these units according to your requirements
    $numbers_name = 'Rupees';
    $decimal_name = 'Paise';
          
    $decimal = round($number - ($no = floor($number)), 2) * 100;
    $hundred = null;
    $digits_length = strlen($no);
    $i = 0;
    $str = array();
    $words = array(0 => '', 1 => 'One', 2 => 'Two',
        3 => 'Three', 4 => 'Four', 5 => 'Five', 6 => 'Six',
        7 => 'Seven', 8 => 'Eight', 9 => 'Nine',
        10 => 'Ten', 11 => 'Eleven', 12 => 'Twelve',
        13 => 'Thirteen', 14 => 'Fourteen', 15 => 'Fifteen',
        16 => 'Sixteen', 17 => 'Seventeen', 18 => 'Eighteen',
        19 => 'Nineteen', 20 => 'Twenty', 30 => 'Thirty',
        40 => 'Forty', 50 => 'Fifty', 60 => 'Sixty',
        70 => 'Seventy', 80 => 'Eighty', 90 => 'Ninety');
    $digits = array('', 'Hundred','Thousand','Lakh', 'Crore');
    while( $i < $digits_length ) {
        $divider = ($i == 2) ? 10 : 100;
        $number = floor($no % $divider);
        $no = floor($no / $divider);
        $i += $divider == 10 ? 1 : 2;
        if ($number) {
            $plural = (($counter = count($str)) && $number > 9) ? 's' : null;
            $hundred = ($counter == 1 && $str[0]) ? ' and ' : null;
            $str [] = ($number < 21) ? $words[$number].' '. $digits[$counter]. $plural.' '.$hundred:$words[floor($number / 10) * 10].' '.$words[$number % 10]. ' '.$digits[$counter].$plural.' '.$hundred;
        } else $str[] = null;
    }
    $numbers_in_words = implode('', array_reverse($str));
    $decimals_in_words = ($decimal > 0) ? " . " . ($words[$decimal / 10] . " " . $words[$decimal % 10]) . ' '.$decimal_name : '';

    return ($numbers_in_words ? $numbers_in_words.' ' . $numbers_name : '') . $decimals_in_words;
}

echo NumbersToWords(870707);

?>

Use this function into your next project.
