Parsing

In an earlier version of Money there was a Money::stringToUnits method which parsed strings and created money objects. When the library started to move away from the ISO-only concept, we realized that there might be other cases when parsing from string is necessary. This led us creating parsers and moving the stringToUnits to StringToUnitsParser (later replaced by DecimalMoneyParser).

Money comes with the following implementations out of the box:

Intl Parser

As its name says, this parser requires the intl extension and uses NumberFormatter. In order to provide the correct subunit for the specific currency, you should also provide the specific currency repository.

Warning

Please be aware that using the intl extension can give different results in different environments.

use Money\Currencies\ISOCurrencies;
use Money\Parser\IntlMoneyParser;

$currencies = new ISOCurrencies();

$numberFormatter = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
$moneyParser = new IntlMoneyParser($numberFormatter, $currencies);

$money = $moneyParser->parse('$1.00');

echo $money->getAmount(); // outputs 100

Decimal Parser

This parser takes a simple decimal string which is always in a consistent format independent of locale. In order to provide the correct subunit for the specific currency, you should provide the specific currency repository.

use Money\Currencies\ISOCurrencies;
use Money\Parser\DecimalMoneyParser;

$currencies = new ISOCurrencies();

$moneyParser = new DecimalMoneyParser($currencies);

$money = $moneyParser->parse('1000', 'USD');

echo $money->getAmount(); // outputs 100000

Aggregate Parser

This parser collects multiple parsers and chooses the most appropriate one based on success to parse. Most parsers throw an exception when the string’s format is not supported.

use Money\Parser\AggregateMoneyParser;
use Money\Parser\BitcoinMoneyParser;
use Money\Parser\IntlMoneyParser;

$numberFormatter = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
$intlParser = new IntlMoneyParser($numberFormatter, 2);
$bitcoinParser = new BitcoinMoneyParser(2);

$moneyParser = new AggregateParser([
    $intlParser,
    $bitcoinParser,
]);

$dollars = $moneyParser->parse('1 USD');
$bitcoin = $moneyParser->parse("\0xC9\0x831.00");

This is very useful if you want to use one parser as a service in DI context.
