In the above, the listing takes a number and formats it, so it conforms to Indian (INR), American (US), and European (EUR) currency conventions. The set locale( ) function sets the locale and hence conventions for currency displays. Notice that the Indian and American locales differ in their placement of thousand separators while the European locale uses commas instead of decimals. Note that the money_format( ) function is not available in the Windows version of PHP.
