Two very usefull functions to have around.

(note: dollarfy requires commify to work)

function commify ($str) { 

        $n = strlen($str); 

        if ($n <= 3) { $return=$str; } 

        else { 

        $pre=substr($str,0,$n-3); 

        $post=substr($str,$n-3,3); 

        $pre=commify($pre); 

        $return="$pre,$post"; 

        }

        return($return); 

}

function dollarfy ($num,$dec) {

        $format="%.$dec" . "f";  

        $number=sprintf($format,$num);

        $str=strtok($number,".");

        $dc=strtok(".");      

        $str=commify($str);

        $return="\$".$str;

        if ($dec!=0) { $return = $return . "." . $dc; } 

        return($return); 

}
