Number to words - PHP Converter

PHP utility for converting arbitrary float or integer number to words, mainly in English, Slovak and Czech. These have custom PHP implementation, which will fix INTL/ICU bugs and allows for output customization. Other languages are supported too, but only using INTL/ICU PHP extension, which might be buggy.

$ composer require "lubosdz/number-to-words" : "~1.0.0"

// Slovensky / Slovak
NumberToWords::convert(123.45, 'sk'); // jednostodvadsaťtri celé štyridsaťpäť
NumberToWords_SK::convert(123.45); // jednostodvadsaťtri celé štyridsaťpäť
NumberToWords_SK::convertIntl(123.45); // jedna­sto dvasať­tri čiarka štyri päť (ICU returns "dvasať", bug)

// supply number as string - will retain right-sided zeroes on decimal part
NumberToWords_SK::convert(37.40); // tridsaťsedem celé štyri - strip off right-sided zeroes
NumberToWords_SK::convert("37.40"); // tridsaťsedem celé štyridsať - keep right-sided zeroes
NumberToWords_SK::convert("37.400"); // tridsaťsedem celé štyristo - keep right-sided zeroes

// arbitrary decimals word separator
NumberToWords_EN::$txtDecimal = " čiarka ";
NumberToWords_EN::convert(12.30); // dvanásť čiarka tridsať

// with decimals as a fraction - useful in accounting
NumberToWords::$decimalsAsFraction = true;
NumberToWords::convert(123.45, 'sk'); // jednostodvadsaťtri (45/100)

// enforce desired number of decimals
NumberToWords::$numberOfdecimals = 2;
NumberToWords::convert(12.3, 'sk'); // dvanásť celé tridsať
