Formatting a number

Question

I have a table with numbers like these:

19809.1
1982.0
1982.19

Its currency. Is there a function I can use to format these numbers like this?

19 809,10
1 982,00
1 982,19

Answer 1

This is quite easy with number_format:

number_format(value, number_of_decimals, "decimal_separator", "thousand_separator")

Something like this:

echo number_format(19809.1, 2, ",", " ");

This tells the number to have 2 decimals, comma , as decimal separator and a whitespace as thousand separator. Output will be:

19 809,10

Other examples:

echo number_format(19809.1, 0, "", ".");
> 19.809
> no decimal and . as thousand separator

echo number_format(19809.1, 3, ".", ",");
> 19,809.100
> 3 decimals, comma as thousand separator and dot as decimal separator
