Never liked printf, why is it doing this?

Why does this:

..........

$sum_value+=$row_array[8];
}
echo "</table>";
echo "<br>Total Value of Orders: ".printf('$%01.2f',
$sum_value)."<br>";
echo "</br>Done";

Result in this?

$20500.00
Total Value of Orders: 9

Done

I have no idea where the '9' came from and why does @sum_value print
before the string?

> $sum_value+=$row_array[8];

You want sprintf(), not printf() above.

What is the return value of printf()? It's *NOT* a string. It's
the length of the string it output.

or structure it like this:

printf("<br>Total Value of Orders: $%01.2f<br>", $sum_value);
