Step.1- First Download nusoap.zip then file paste inside the xmpp->htdoc->project folder.

                   Download File Here - https://app.box.com/s/68003401def76c67d0d3

Step.2- Create a file soap_page.php.

require_once('lib/nusoap.php'); $server = new nusoap_server; //$server ->configureWSDL('server', 'urn:server'); //$server ->wsdl->schemaTargetNamespace = 'urn:server'; //$server ->register('pollServer', array('value' => 'xsd:string'), array('return' => 'xsd:string'), 'urn:server', 'urn:server#pollServer'); //register a function that works on server $server->register('getInfo'); // create age calculation function function find_age($birthday) { list($byear, $bmonth, $bday) = explode('-', $birthday); list($cyear, $cmonth, $cday) = explode('-', date('Y-m-d')); $cday -= $bday; $cmonth -= $bmonth; $cyear -= $byear; if($cday < 0) $cmonth--; if($cmonth < 0) $cyear--; return $cyear; } // create the function function getInfo($name, $birthday) { $result['status'] = true; if(!$name){ return new soap_fault('Client','','softwarequery!'); } // Return if you would like to check server response else delete this line. return $result = array('name'=> $name,'age'=> find_age($birthday) ); $conn = mysql_connect('localhost','root',''); mysql_select_db('webservice', $conn); $sql = "SELECT * FROM books"; $q = mysql_query($sql); $result = array(); while($row = mysql_fetch_array($q)) { $result[] = array( 'cd'=>$row['cd'], 'title'=>$row['title'], 'author'=>$row['author'], 'publisher'=>$row['publisher'] ); } return $result; } $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server ->service($HTTP_RAW_POST_DATA); exit();

Step.3-After creating a soap.page.php file then create a client_page.php file inside the file paste the all code.

header('Content-type: text/html'); $client = new nusoap_client('http://localhost/soapserver/soap_page.php'); $err = $client->getError(); if ($err) { echo ' Constructor error ' . $err . ' '; } $param = array( 'name' => 'softwarequery','birthday'=>'1999-09-34'); $response = $client->call('getInfo',$param); var_dump($response); if($client->fault) { echo "FAULT: Code: (".$client->faultcode.") "; echo "String: ".$client->faultstring; } else { echo $response['name']."\n Age: ".$response['age']."'s"; } echo '<h2> Request</h2> <>' . htmlspecialchars($client->request, ENT_QUOTES) . '</br> '; echo '<h2> Response</h2> <br>' . htmlspecialchars($client->response, ENT_QUOTES) . '</br> '; Step.4- After creating all code go to the browser then type http://localhost/client_page.php.you will respond to "Name" and "Date of Birth".
