[Editor's note: Usually it will be simpler to use number_format() to generate the type of
output the code below produces. The built-in function would be faster than using a regular
expression.]
here is a simple function to add commas to a number.
function comma_format($num){
$number = sprintf("%01.2f", $num);
while (preg_match("!(-?\d+)(\d\d\d)!", $number))
{
$number = preg_replace("!(-?\d+)(\d\d\d)!","$1,$2", $number);
}
return $number;
}
