Brick\Money VS Money

brick/money: A money and currency library for PHP

1 - Floating point is not always great for money operations and can introduce odd rounding errors - https://www.php.net/manual/en/language.types.float.php - you might want to use something like this: https://github.com/brick/money

He should have said to use Brick/Money https://github.com/brick/money which is based on Brick/Math but is specifically money related.

If you don’t want to do the integer conversions yourself, I highly recommend looking at: https://github.com/brick/money

brick/date-time is great! I personally prefer its interface and functionality over Carbon's. I also really like his money library

Is the most popular, but https://github.com/brick/money is preferrable IMO. One of the reasons is that it handles not just money, but all arbitrary precision calculations independent of currecy via brick/math.

Yeah. Don’t use floats for money...always think of them as approximations. And consider packages like https://github.com/brick/money among others.

moneyphp: PHP implementation of Fowler's Money pattern

There's also https://github.com/moneyphp/money, which is great.

Or you can use MoneyPHP, which uses BCMath, and it takes care of all of your problems.

Instead, you want to use a Money object of some sort instead; e.g. https://github.com/moneyphp/money.

Yeah I usually use moneyphp for this

https://github.com/moneyphp/money to handle money

With that in place, let's talk about our test project for a minute. We are going to build a small library on top of Money, a popular PHP package facilitating the manipulation of monetary values and currencies.

In addition to the essential advice above to use Integers of the lowest denomination to store prices, you can also look into using a library to help with all the money math, conversions, comparisons etc https://github.com/moneyphp/money
