number_format ( float number [, int decimals])
string
number_format ( float number, int decimals, string dec_point, string thousands_sep)
number_format() returns a formatted version of
number. This function accepts either one,
two or four parameters (not three):
If only one parameter is given,
number will be formatted without decimals,
but with a comma (",") between every group of thousands.
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.
If all four parameters are given, number
will be formatted with decimals decimals,
dec_point instead of a dot (".") before
the decimals and thousands_sep instead of
a comma (",") between every group of thousands.
Only the first character of thousands_sep
is used. For example, if you use foo as
thousands_sep on the number
1000, number_format() will
return 1f000.
Example 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;
$english_format_number = number_format($number);
$nombre_format_francais = number_format($number, 2, ',', ' ');
$number = 1234.5678;
$english_format_number = number_format($number, 2, '.', '');
?>
