How do I format a number to a dollar amount in PHP

Question

How do you convert a number to a string showing dollars and cents?

eg:
123.45    => '$123.45'
123.456   => '$123.46'
123       => '$123.00'
.13       => '$0.13'
.1        => '$0.10'
0         => '$0.00'

Answer 1

PHP also has money_format().

Here's an example:

echo money_format('$%i', 3.4); // echos '$3.40'

This function actually has tons of options, go to the documentation I linked to to see them.

Note: money_format is undefined in Windows.

Answer 2

If you just want something simple:

'$' . number_format($money, 2);

number_format()

Answer 3

i tried money_format() but it didn't work for me at all. then i tried the following one. it worked perfect for me. hopefully it will work in right way for you too.. :)

you should use this one

number_format($money, 2,'.', ',')

it will show money number in terms of money format up to 2 decimal.

Answer 4

In PHP and C++ you can use the printf() function

printf("$%01.2f", $money);

Answer 5

In php.ini add this (if it is missing):

#windows
extension=php_intl.dll

#linux
extension=php_intl.so

Then do this:

$amount = 123.456;

// for Canadian Dollars
$currency = 'CAD';

// for Canadian English
$locale = 'en_CA';

$fmt = new \NumberFormatter( $locale, \NumberFormatter::CURRENCY );
echo $fmt->formatCurrency($amount, $currency);
