Example #1 number_format() Example
For instance, French notation usually use two decimals, comma (',') as decimal separator, and space (' ') as thousand separator. The following example demonstrates various way to format a number:
<?php
$number = 1234.56;
// english notation (default)
$english_format_number = number_format($number);
// 1,235
// French notation
$nombre_format_francais = number_format($number, 2, ',', ' ');
// 1 234,56
$number = 1234.5678;
// english notation without thousands separator
$english_format_number = number_format($number, 2, '.', '');
// 1234.57
?>
