Format output in currency round 2 decimals so it displays 12.99 not 12.9978

[iBuddy_Media]

<font face="Verdana, Arial, Helvetica, sans-serif"><font size="2">
<?

$fee = $amount * (0.029);
$net = $fee + (0.30);
$total = $amount - $net;

echo "<b>Total Amount:</b> <br>$amount <br>";
echo "<b>Fee Amount:</b> <br>$net <br>";
echo "<b>Net Amount:</b> <br>$total";

?>
</font></font>
<form name="form1" method="post" action="<? $PHP_SELF; ?>">
  <input name="amount" type="text" id="amount">
  <input type="submit" name="Submit" value="Submit">
</form>

This is just a simple script im writing for paypal fees. How can I make the output selection format to 2 decimals?

I would advise using integers to deal with money.

Still, you can use round()
i.e.
$total = round($total, 2);

you can always use sprintf.

$total = sprintf("%01.2f", $total);
