Number conversion to string (laravel)

Question

I'm new in Laravel and I'm trying to convert a number/amount to string in laravel.

Example: Number/amount: 1,500 Converted: One Thousand, Five Hundred

How do I suppose to do that? please help thanks

Answer 1

Use PHP NumberFormatter class for conversion :

$digit = new NumberFormatter("en", NumberFormatter::SPELLOUT);
echo $digit->format(1000);

Output will be: one thousand

You can access the function wherever you want within the program as

Classname::convert_number_to_words(123456789.123);
// one hundred and twenty-three million, four hundred and fifty-six thousand, seven hundred and eighty-nine point one two three
