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.
