In PHP, what are some best practices for converting numerical data into words for display purposes?

When displaying numerical data in a user-friendly way, it is often necessary to convert numbers into words. One common approach is to use a library or function that can handle this conversion. In PHP, the `NumberFormatter` class can be used to achieve this. By creating an instance of `NumberFormatter` and setting the locale to the desired language, you can easily convert numerical data into words for display purposes. 

$number = 1234;
$locale = 'en_US';
$fmt = new NumberFormatter($locale, NumberFormatter::SPELLOUT);
$numberInWords = $fmt->format($number);

echo $numberInWords; // Outputs: one thousand two hundred thirty-four
