formatting – Print Currency Number Format in PHP

Posted by: admin April 23, 2020 Leave a comment

Questions:

I have some price values to display in my page.

I am writing a function which takes the float price and returns the formatted currency val with currency code too..

For example, fnPrice(1001.01) should print $ 1,000.01

How to&Answers:

The easiest answer is number_format().

echo "$ ".number_format($value, 2);

If you want your application to be able to work with multiple currencies and locale-aware formatting (1.000,00 for some of us Europeans for example), it becomes a bit more complex.

There is money_format() but it doesn’t work on Windows and relies on setlocale(), which is rubbish in my opinion, because it requires the installation of (arbitrarily named) locale packages on server side.

If you want to seriously internationalize your application, consider using a full-blown internationalization library like Zend Framework’s Zend_Locale and Zend_Currency.

Answer:

with the intl extension in PHP 5.3+, you can use the NumberFormatter class:

$amount = '12345.67';

$formatter = new NumberFormatter('en_GB',  NumberFormatter::CURRENCY);
echo 'UK: ', $formatter->formatCurrency($amount, 'EUR'), PHP_EOL;

$formatter = new NumberFormatter('de_DE',  NumberFormatter::CURRENCY);
echo 'DE: ', $formatter->formatCurrency($amount, 'EUR'), PHP_EOL;

which prints :

 UK: €12,345.67
 DE: 12.345,67 €

Answer:

sprintf() is the PHP function for all sorts of string formatting
http://php.net/manual/en/function.sprintf.php

I use this function:

function formatDollars($dollars){
  return '$ '.sprintf('%0.2f', $dollars);
}

Answer:

I built this little function to automatically format anything into a nice currency format.

function formatDollars($dollars)
{
    return "$".number_format(sprintf('%0.2f', preg_replace("/[^0-9.]/", "", $dollars)),2);
}

Edit

It was pointed out that this does not show negative values. I broke it into two lines so it’s easier to edit the formatting. Wrap it in parenthesis if it’s a negative value:

function formatDollars($dollars)
{
    $formatted = "$" . number_format(sprintf('%0.2f', preg_replace("/[^0-9.]/", "", $dollars)), 2);
    return $dollars < 0 ? "({$formatted})" : "{$formatted}";
}

Answer:

From the docs

<?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

?>

Answer:

PHP has a function called money_format for doing this. Read about this here.
