Hi all,

I am learning php.

I have created Web Service in php using nusoap.dll. I have written price test method it's return integer it's working fine, but when I fetch database, to return array it's returning error. I had tried to resolve the error, but it's still giving error.

Could you tell me where I went wrong.

my php code is:

service.php

<?php

/**
 * @author 
 * @copyright 2013
 */

require 'lib/nusoap.php';
require 'functions.php';

$server = new nusoap_server();
$server -> configureWSDL('WS'.'urn:WS');
$server -> register(
                    "price", //name of the function
                    array("name" => 'xsd:string'), //inputs
                    array("return" => 'xsd:inter')  //outputs
                    );

$server -> register(
                    "ReadBooks", //name of the function
                    array("productid" => 'xsd:inter'), //inputs
                    array("return" => 'xsd:unbounded')  //outputs
                    );
                    
/**
 * $server -> register(
 *                     "countbooks", //name of the function
 *                     array(), //inputs
 *                     array()  //outputs
 *                     );
 */
                    
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);

?>

functions.php

<?php

/**
 * @author 
 * @copyright 2013
 */

function price($name){
    
    $details=array('abc'=>100,
                   'xyz'=>200);
    foreach($details as $n => $p){
        if($name==$n){
            $prices = $p;
        }
    }
    return $prices;
}

function ReadBooks($productid)
{
    mysql_connect("localhost","root","") or die(mysql_error());
    mysql_select_db("Sample") or die(mysql_error());
    $myQuery='Select * from php_shop_products where product_id='.$productid;
    $results = mysql_query($myQuery);
    if($results===false){
        return die($myQuery."<br/><br/>".mysql_error());
    }
    else{
        return $results;
    }
    return die(mysql_error());
}

/*$results =ReadBooks(1);

while($row =mysql_fetch_array($results)){
    echo $row['name'];
}*/


?>

client.php

<?php

/**
 * @author 
 * @copyright 2013
 */

require 'lib/nusoap.php';

$client = new nusoap_client("http://localhost:8080/myfiles/examples/WS/service.php?wsdl");
$book_name="xyz";
$prices=$client->call('price',array("name"=>"$book_name"));

echo $prices . '<br/>';


$productid=1;
$results=$client->call('ReadBooks',array("productid"=>$productid));

while($row =mysql_fetch_array($results)){
    echo $row['name'];
}



?>

它返回错误：

it's returning error:

First function result : 200 //success

//second function error

Warning: mysql_fetch_array() expects parameter 1 to be resource, string given in C:\xampp\htdocs\myfiles\examples\WS\client.php on line 20

你能告诉我哪里出错了。

Thanks in advance...

推荐答案

server = new nusoap_server（）;

server = new nusoap_server();

server - > configureWSDL（'WS'。'urn：WS'）;

server -> configureWSDL('WS'.'urn:WS');

server - >注册（
price，//函数名称
array（name=>'xsd：string'），//输入
array（return=> 'xsd：inter'）//输出
）;

server -> register( "price", //name of the function array("name" => 'xsd:string'), //inputs array("return" => 'xsd:inter') //outputs );
