PHP Currency formatting trailing zeros

Question

Is it possible to have PHP format currency values, for example: $200 will output as: $200 (without decimals) but with a number like $200.50 it will correctly output $200.50 instead of $200.5?

Thanks! :)

Answer 1

$num_decimals = (intval($amt) == $amt) ? 0 :2;
print ("$".number_format($amt,$num_decimals);

Answer 2

If you don't mind handling the currency on your own, you can simply use the following on the number, to get the correct output.

This solution will always output trailing zeros (xx.x0 or xx.00 depending on the provided number)

$number = 1234
sprintf("%0.2f",$number);
// 1234.00
