What are the recommended functions or libraries for handling currency values accurately in PHP?

When working with currency values in PHP, it is important to handle them accurately to avoid rounding errors and ensure precision. One recommended way to handle currency values accurately in PHP is by using the `NumberFormatter` class provided by the `intl` extension. This class allows you to format currency values according to different locales and provides accurate rounding for currency calculations. 

$amount = 10.555;
$formatter = new NumberFormatter('en_US', NumberFormatter::CURRENCY);
echo $formatter->formatCurrency($amount, 'USD');
