You know those stupid little things you come accross after years in the profession, that make you say "Golly, if I'd just known that 3 or 4 years ago, it would have saved a ton of work!" This is one of them.

what is the easiest way to express a formatted dollar amount?

                            

                            <? echo(sprintf("$ %.2f",$amount)); ?>


                            Here is a more robust function:

                            

                            <? function dispdollars($amount, $style)

                            {

                               //slam it!

                               $amount=doubleval($amount);

                            

                               if ($amount>=0)

                                  echo(sprintf("$ %.2f",$amount);

                               else

                                  if ($style==0)

                                     echo(sprintf("-$ %.2f",-$amount);

                                  else

                                     echo("<font color=red>".sprintf("$ %.2f",-$amount)."</font>");

                            

                            }

Usage Example

<html>

                            <?

                               $amount=1.2345;

                            

                               echo("the value $amount expressed in dollars is ".dispdollars($amount).".");

                            
 ?>


                            </html>
