Not getting response using SOAP and PHP


I'm using PHP5 and NuSOAP - SOAP Toolkit for PHP. I created the server using the code below:

<?php function getStockQuote($symbol) { mysql_connect('localhost','user','pass'); mysql_select_db('test'); $query = "SELECT stock_price FROM stockprices WHERE stock_symbol = '$symbol'"; $result = mysql_query($query); $row = mysql_fetch_assoc($result); echo $row['stock_price']; } $a=require('lib/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); ?>

The client has the following code:

<?php require_once('lib/nusoap.php'); $c = new soapclientNusoap('http://localhost/stockserver.php?wsdl'); $stockprice = $c->call('getStockQuote', array('symbol' => 'ABC')); echo "The stock price for 'ABC' is $stockprice."; ?>

The database was created using the code below:

CREATE TABLE `stockprices` ( `stock_id` INT UNSIGNED NOT NULL AUTO_INCREMENT , `stock_symbol` CHAR( 3 ) NOT NULL , `stock_price` DECIMAL(8,2) NOT NULL , PRIMARY KEY ( `stock_id` ) ); INSERT INTO `stockprices` VALUES (1, 'ABC', '75.00'); INSERT INTO `stockprices` VALUES (2, 'DEF', '45.00'); INSERT INTO `stockprices` VALUES (3, 'GHI', '12.00'); INSERT INTO `stockprices` VALUES (4, 'JKL', '34.00');

When I run the client the result I get is this:


The stock price for 'ABC' is .


75.00 is not being printed as the price.


the return method is missing in the function, maybe that is the problem.

return $row['stock_price'];
