How to write SOAP web service using PHP?

In my previous post i have explained "How to read gmail inbox using PHP". Today I am going to write on Web service using SOAP. If you are a newbie and have a question in mind that "How to create a SOAP service?" this article will be useful to get started. Here are few easy steps to follow.

[NB: If you are facing trouble with below code then please do visit my latest updated post "SOAP web service using PHP". ]

Step 1 :

Download nusoap library file from here. Unzip and copy the folder into www (WAMP) root folder. If you are using Xampp tool paste it into htdocs/xampp/ folder.

Step 2 :

Now lets create two php file one is server.php and another client.php.

Step 3 :

Copy below snippet into your server.php.

 
     require_once('lib/nusoap.php');
 $server = new nusoap_server;
/*
//require("Connection.class.php"); 
$server ->configureWSDL('server', 'urn:server');
$server ->wsdl->schemaTargetNamespace = 'urn:server';
$server ->register('mpollServer', array('value' => 'xsd:string'), 
                    array('return' => 'xsd:string'), 'urn:server', 'urn:server#mpollServer');
*/

//register a function that works on server
$server ->register('getfeedDetails', array('value' => 'xsd:string'), 
                   array('return' => 'xsd:string'), 'urn:server', 'urn:server# getfeedDetails');

// create the function to fetch Data’s from Database
function getfeedDetails ()
{
   $conn = mysql_connect('localhost','root','');
   mysql_select_db('news', $conn);
   $sql = "SELECT * FROM user_story";
   $q = mysql_query($sql);
   $items = array();
   while($row = mysql_fetch_array($q)){

       $items [] = array(
            'story_url'=> $row['story_url'],
            'story_title'=> $row['story_title'],
            'story_description'=> $row['story_description'],
            'story_image'=> $row['story_image']
       );
    }
   return $items;
}

$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server ->service($HTTP_RAW_POST_DATA);


      

Above code snippet will help your to access database and fetch details.

Step 4 :

Now let us open client.php and paste below code snippet into it. You have to create a client object and call your server method to retrieve the results from server.

require_once('lib/nusoap.php');
$url = "http://localhost/testserver/server.php?wsdl";
$client = new nusoap_client($url);
//Call server function
$response = $client ->call(' getfeedDetails ');

if($client->fault)
{
    echo "FAULT: Code: (".$client ->faultcode.")";
    echo "String: ".$client->faultstring;exit;
}
else
{
                $result = $response;
                $count = count($result);
?>
    >
                <table>
    <tbody><tr>
                <th>Story Url</th>
                <th>Story Title</th>
                <th>Story Description</th>
                <th>Story Image</th>
    </tr>
    
    <tr echo="" php="" rowtype=""><td></td>
                <td></td>
                <td></td>
                <td><img src="<?php echo $result[$i]['story_image']?>" type="photo" /> </td>
    </tr>
    
    </tbody></table>
 <php } ?>   
   
<style type="text/css">
    th {
        background:#007F99;
        color:#fff;
    }
</style>

      

Step 5 :

Thats it! We are done. Now go to browser and run client.php. It will call the SOAP server and fetch you the details from database.
