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.
