If two parameters are given, number will be formatted with decimals decimals with a dot (".") in front, and a comma (",") between every group of thousands.

Пример 1. number_format() Example

For instance, French notation usually use two decimals, comma (',') as decimal separator, and space (' ') as thousand separator. This is achieved with this line : 

<?php

    $number = 1234.56;

    // english notation (default)
    $english_format_number = number_format($number);
    // 1,234

    // French notation
    $nombre_format_francais = number_format($number, 2, ',', ' ');
    // 1 234,56

    $number = 1234.5678;

    // english notation without thousands seperator
    $english_format_number = number_format($number, 2, '.', '');
    // 1234.57

?>
