Creating Web Service Using PHP

Step 1: You will download the library from http://sourceforge.net/projects/nusoap/.
Step 2: Run WAMP server, then you will go to www root folder location.
Step 3: Create folder, it’s called “WebServiceSOAP” into www root folder.
Step 4: Paste "lib" folder inside your "www/WebServiceSOAP/" location from Step 1 download files.
Step 5: Create two files “server.php” and “client.php” into WebServiceSOAP folder location.
Step 6: Inside “server.php”, please write the code lines given below:

Hide   Copy Code

<?php
//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('get_message'); 

// create the function 
function get_message($your_name) 
{ 
if(!$your_name){ 
return new soap_fault('Client','','Put Your Name!'); 
} 
$result = "Welcome to ".$your_name .". Thanks for Your First Web Service Using PHP with SOAP"; 
return $result; 
} 
// create HTTP listener 
$server->service($HTTP_RAW_POST_DATA); 
exit(); 
?>  

Step 7: After creating “server.php” file, now we will test this server function. Please go to URL & type http://localhost/WebServiceSOAP/server.php?wsdl.
Step 8: Create "client.php" file into WebServiceSOAP folder location. Please find the following code lines:

Hide   Copy Code

<?php 
require_once ('lib/nusoap.php'); 
//Give it value at parameter 
$param = array( 'your_name' => 'Monotosh Roy'); 
//Create object that referer a web services 
$client = new soapclient('http://localhost/WebServiceSOAP/server.php'); 
//Call a function at server and send parameters too 
$response = $client->call('get_message',$param); 
//Process result 
if($client->fault) 
{ 
echo "FAULT: <p>Code: (".$client->faultcode."</p>"; 
echo "String: ".$client->faultstring; 
} 
else 
{ 
echo $response; 
} 
?> 

Step 9: Save all codes, then please go to URL and type http://localhost/WebServiceSOAP/client.php.
