Question

Why does this error occurs?

code:

setlocale(LC_MONETARY, "en_US");
$pricetotal = money_format("%10.2n", $pricetotal);

Server details.

Apache Version : 2.2.21  
PHP Version : 5.3.8 

I’m getting the following Error

Fatal error: Call to undefined function money_format() 

Answer 1

From the manual:

The function money_format() is only defined if the system has strfmon
capabilities. For example, Windows does not, so money_format() is
undefined in Windows.

money_format() is basically a wrapper around the C library function strfmon() as the manual states.

If you check the comments, there is an implementation by Rafael M. Salvioni. Worth a try. You can check if it’s already defined using function_exists().
