没有逗号的PHP数字格式

Question

I want to display the number 1000.5 like 1000.50 with 2 decimal places and no commas/thousands separators.

I am using number_format to achieve this:

number_format(1000.5, 2);

This results 1,000.50. The comma (,) separator appended in thousand place which is not required in the result.

How can I display the number with a trailing zero and no comma?

Answer 1

See the documentation for number_format: http://php.net/number_format

The functions parameters are:

string number_format ( float $number , int $decimals = 0 , string $dec_point = '.' , string $thousands_sep = ',' )

So use:

number_format(1000.5, 2, '.', '');

Which means that you don't use any (= empty string) thousands separator, only a decimal point.
