String manipulation help needed

[dwest]

Hi,

I have a piece of data supplied as a dollar amount:

Example:

$1.95

 

However, if the dollar amount happens to end in zero, then is is supplied without the zero.

Example:

$1.9

 

So, I need to test for the second digit after the decimal and if it isn't there, add a zero.

 

How can I do that?

 

Maybe regexp is applicable here??

 

Any help would be greatly appreciated.

 

Thanks!

You just need the number_format() function.

 

<?php

$amount = 1.9;
$amount = number_format($amount, 2);

echo "$$amount";

?>
