How to create webservices in PHP tutorial

Here I am showing one example of creating the webservices in php

First you need to download the soap library to create the webservies on the server

You can download it from the link http://sourceforge.net/projects/nusoap/

After that you need to create server.php file on you server

Server.php

<?php

//call library

require_once ('lib/nusoap.php'); // include the soap liberary here

function getProd($category) {

if ($category == "movies") { // here I am checking the coming value from category is movies or not

return join(",", array(

"The is webservices test",

" Writing webservice I am here ",

"Build dynamic website with me")); // if category is movies then it will send this result to your server

}

else {

return "No products listed under that category"; // if there is other category then movies it will show this message

}

$server = new soap_server();

$server->register("getProd");

$server->service($HTTP_RAW_POST_DATA);

Need to create the files newservice.php

<?php /* require the user as the parameter */

if(isset($_GET['user']) && intval($_GET['user'])) {

/* soak in the passed variable or set our own */

$number_of_posts = isset($_GET['num']) ? intval($_GET['num']) : 10; //10 is the default

$format = strtolower($_GET['format']) == 'json' ? 'json' : 'xml'; //xml is the default

$user_id = intval($_GET['user']); //no default

/* connect to the db */

$link = mysql_connect('localhost','username','password') or die('Cannot connect to the DB');

mysql_select_db('database name,$link) or die('Cannot select the DB');

/* grab the posts from the db */

$query = "SELECT post_title, guid FROM table WHERE post_author = $user_id AND post_status = 'publish' ORDER BY ID DESC LIMIT $number_of_posts";

$result = mysql_query($query,$link) or die('Errant query: '.$query);

/* create one master array of the records */

$posts = array();

if(mysql_num_rows($result)) {

while($post = mysql_fetch_assoc($result)) {

$posts[] = array('post'=>$post);

}

/* output in necessary format */

if($format == 'json') {

header('Content-type: application/json');

echo json_encode(array('posts'=>$posts));

}

else {

header('Content-type: text/xml');

echo '<posts>';

foreach($posts as $index => $post) {

if(is_array($post)) {

foreach($post as $key => $value) {

echo '<',$key,'>';

if(is_array($value)) {

foreach($value as $tag => $val) {

echo '<',$tag,'>',htmlentities($val),'</',$tag,'>';

}

echo '</',$key,'>';

}

echo '</posts>';

}

/* disconnect from the db */

@mysql_close($link);

}

Now we need to create file client.php

if(isset($_REQUEST['get_data']))

{

$userid = $_REQUEST['userid'];

$count = $_REQUEST['count'];

$url = “Api file path/newservice.php?user=$userid&num=$count&format=json";

$client = curl_init($url);

curl_setopt($client,CURLOPT_RETURNTRANSFER,1);

// get responce

$response = curl_exec($client);

// decode

//echo "<pre>";

//print_r($response);

$result = json_decode($response); // to decode the json result

//echo "<pre>";

//print_r($result);

}

<form method="post">

User ID <input type="text" name="userid" value="">

Number <input type="text" name="count" >

<input type="submit" name="get_data" value="Get Data">

</form>

Incoming results will show here on your file .

foreach($result as $rr)

{

foreach($rr as $kk)

{

echo $kk->post->post_title."<br/>";

//echo $k;

// echo $rr;

//echo "<pre>";

//print_r($kk);

//echo $rr[$k]->post->post_title ."<br/>";

}
