PHP implementation of Fowler's Money pattern.


Build Status

PHP 5.5+ library to make working with money safer, easier, and fun!

"If I had a dime for every time I've seen someone use FLOAT to store currency, I'd have $999.997634" -- Bill Karwin

In short: You shouldn't represent monetary values by a float. Wherever you need to represent money, use this Money value object. Since version 3.0 this library uses strings internally in order to support unlimited integers.


use Money\Money;

$fiveEur = Money::EUR(500);
$tenEur = $fiveEur->add($fiveEur);

list($part1, $part2, $part3) = $tenEur->allocate(array(1, 1, 1));

$ composer test


We would love to see you helping us to make this library better and better. Please keep in mind we do not use suffixes and prefixes in class names, so not CurrenciesInterface but Currencies. Other than that, Style CI will help you using the same code style as we are using. Please provide tests when creating a PR and clear descriptions of bugs when filing issues.

This library is heavily inspired by Martin Fowler's Money pattern. A special remark goes to Mathias Verraes, without his contributions, in code and via his blog, this library would not be where it stands now.
