Format results?

[kooks]

Hello,

Could somebody help me with this?
I know how to format numbers $number = number_format($number); and so on . . .

What I don't know is: How to apply this to results of a query like this:

$result=mysql_query ("SELECT * FROM stuff WHERE this='$this' and that='$that' LIMIT $offset,$limit");
while ($b = mysql_fetch_array($result)) {
printf( "This: %s That: %s Cash: %s\n", $b[this], $b[that], $b[cash]);
}

How can I format the output of cash?

Thank You,

$result=mysql_query ("SELECT * FROM stuff WHERE this='$this' and that='$that' LIMIT $offset,$limit"); 
while ($b = mysql_fetch_array($result)) {
    //HERE YOU FORMAT THE VARIABLE $b[cash]
    $b[cash] = number_format($b[cash]); //FORMAT IT HERE HOWEVER YOU NEED IT
    printf( "This: %s That: %s Cash: %s\n", $b[this], $b[that], $b[cash]); 
}
