Dollar exchange rate display script

[Naughty]

Does anybody have, or know of a script that will allow me to display the dollar exchange rate as a variable?

E.g. in php echo:
Your price is based on $usdrate USD/Euro.

xe.com already does it for you

I'm not. We just need it inside our admin area to update dbase records according to the newest rates. Once or twice weekly.

I know osCommerce has this thing that updates currencies in the admin panel, also through XE. I'll see if i can find that code

If anybody needs it, here goes....

<?php


function quote_xe_currency($to, $from = 'EUR') {
    $page = file('http://www.xe.net/ucc/convert.cgi?Amount=1&From=' . $from . '&To=' . $to);

    $match = array();

    preg_match('/[0-9.]+\s*' . $from . '\s*=\s*([0-9.]+)\s*' . $to . '/', implode('', $page), $match);

    if (sizeof($match) > 0) {
      return $match[1];
    } else {
      return false;
    }
  }
  
  print quote_xe_currency('USD', 'EUR');
?>
