Problems with nuSOAP on my first ever API attempt

[d3ngar]

Hi there,

I'ver tried to build my first API from a very basic example I saw online. Since it didn't work so well initially, I copied the exact code in the end, tried again, but no cigar. I'm not sure what could be wrong here, but I do get a server 500 message when I try to load the client.

However, the API URL seems to work fine: http://dev.badgercomp.com/api/testapi.php

Here is the server code:

<?php
function getStockQuote($symbol) {
	include('dbconnection.php');

$query = "SELECT stock_price FROM stockprices "
       . "WHERE stock_symbol = '$symbol'";
$result = mysql_query($query);

$row = mysql_fetch_assoc($result);
return $row['stock_price'];
}

require('nusoap.php');

$server = new soap_server();

$server->configureWSDL('stockserver', 'urn:stockquote');

$server->register("getStockQuote",
                array('symbol' => 'xsd:string'),
                array('return' => 'xsd:decimal'),
                'urn:stockquote',
                'urn:stockquote#getStockQuote');

$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA)
                      ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>

And here is the client code:

<?php
require('nusoap.php');

$c = new soapclient('http://dev.badgercomp.com/api/testapi.php');

$stockprice = $c->call('getStockQuote',
              array('symbol' => 'ABC'));

echo "The stock price for 'ABC' is $stockprice.";

?>

This all seems easy enough, so I can't understand why it won't work. Any advice?
