PHP Web Services Tutorial: We ever talk about web services at here. In this post, we talk about how to create data array in server. Client will send two data: name and birthday. In the same time, client will fetch array ( name and age). It is realy simple.

I modify from our practice about web services. Create "server_array.php". Placed within (example) www/test/nusoap. Enter this codes:

 <?
 //call library
 require_once ('lib/nusoap.php');

 //using soap_server to create server object
 $server = new soap_server;

 //register a function that works on server
 $server->register('hello');

 // 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 hello($name,$birthday)
 {

   	if(!$name){
    		return new soap_fault('Client','','Put your name!');
   	}

  	$result = array('name'=>$name,'age'=>find_age($birthday));
  	return $result;

 }

 // create HTTP listener
 $server->service($HTTP_RAW_POST_DATA);
 
 exit();
 
 ?>

Now, this is client side. Create "client_side.php". Put within www/test/nusoap. Enter following codes:

<?
require_once ('lib/nusoap.php');

$param = array( 'name' => 'Babablackship','birthday'=>'1980-12-24');

$client = new soapclient('http://localhost:8048/test/nusoap/server_array.php');

$response = $client->call('hello',$param);

if($client->fault)
{
	echo "FAULT: <p>Code: (".$client->faultcode.")</p>";
	echo "String: ".$client->faultstring;
}
else
{
	echo $response['name'];
	echo "<br>";
	echo "Age: ".$response['age']."'s";
}
?>

Ok. Now, point your browser to http://localhost/nusoap/test/client_array.php. You must see like this:
