How to write SOAP web service using PHP?

    How to write web service using SOAP in PHP?

              

             In my previous post I had shown you “how to read gmail inbox using PHP”. Today I am writing my web service using SOAP. If you are wondering “How to create SOAP service?” , Then solution is here. Here I have createdwebservice. All you need to do is, you just have to call service and function to perform particular task.

So let’s follow steps to do this stuffs,

Step 1 : Download nusoap zip file from here.  And paste it inside your www folder if you are using wamp, for xampp user paste it inside htdocs/xampp folder.

Step 2:  create two file call server.php and client.php.

Step 3 :  Inside server.php write below lines of code.

<?php

require_once('lib/nusoap.php');

//require("Connection.class.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('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);

?>

         That’s it you have created your server file to access and fetch details from database.

Step 4:    Now create client.php and inside it just  write below code. Create client object and call your server function to retrieve details.

<?php

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: <p>Code: (".$client ->faultcode.")</p>";

                echo "String: ".$client->faultstring;

}

else

{

                $result = $response;

                $count = count($result);

?>

    <table >

    <tr>

                <th>Story Url</th>

                <th>Story Title</th>

                <th>Story Description</th>

                <th>Story Image</th>

    </tr>

    <?php

    for($i = 0;$i < $count-1;$i++) {

                  $rowtype = ($i % 2) ? "style='background:#88DAEB'": "style=background:#FFF";

        ?>

    <tr <?php echo $rowtype; ?>>

                <td><?php echo $result[$i]['story_url']?></td>

                <td><?php echo $result[$i]['story_title']?></td>

                <td><?php echo $result[$i]['story_description']?></td>

                <td><img src="<?php echo $result[$i]['story_image']?>" type="photo"></td>

    </tr>

    <?php

                }

                ?>

    </table>

    <?php

}

 ?>

<style type="text/css">

    th {

        background:#007F99;

        color:#fff;

    }

</style>

?>

Step 5:   That’s it you have done. Now run your client.php in your browser. It will call server and fetch the details from database.  

So today I have shown you how to use simple SOAP webservice and to get details from database.
