Outputting list of variables in a select

[Bayliss Trevor]

Hi all,
I am trying to output a list of values in a select.
I don't get an error but it doesn't show anything, why is that? Thank you

<form action="ws.php" method="get">
<p>
Convert from:

<?php
require_once 'lib/nusoap.php';

$oClient   = new nusoap_client(
    'http://www.webservicex.net/CurrencyConvertor.asmx?WSDL',
    TRUE // Needs to be TRUE because we are using WSDL
);
$oResponse = $oClient->call(
    'Currency',
    array(
        'FromCurrency' => 'USD',
        'ToCurrency'   => 'CAD'
    )
);

echo $fCurrency; 



?>

<select name="FromCurrency">
<option value="<?php print_r($fCurrency);?>"><?php print_r($fCurrency); ?></option>
</select>
</p>

<input type="submit" />

 </form>

I don't think print_r is what you intended to use here. Its output within the value attribute of the option element would not be valid HTML.

Additionally, $fCurrency is not assigned a value anywhere in your code

Thanks for the reply Dan, should I use echo instead then?

I was able to output all the vars using this code:
<?php
$vars = get_defined_vars();
print_r($vars);
?>

How do I output only the webservice vars? Thanks
