currency(mixed $number, string $currency= 'USD')

This method is used to display a number in common currency formats (EUR,GBP,USD). Usage in a view looks like:

<?php echo $number->currency($number,$currency); ?>

1. <?php echo $number->currency($number,$currency); ?>

The first parameter, $number, should be a floating point number that represents the amount of money you are expressing. The second parameter is used to choose a predefined currency formatting scheme:

HTML entities are outputted as currency symbols where needed.

If a non-recognized $currency value is supplied, it is prepended to a USD formatted number. For example:

<?php echo $number->currency('1234.56', 'FOO'); ?>
 
//Outputs: 
FOO 1,234.56

1. <?php echo $number->currency('1234.56', 'FOO'); ?>
3. //Outputs:
4. FOO 1,234.56
