How to implement web services in php

This article mainly introduces the method of implementing web services in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

The example in this article describes how PHP uses NuSOAP to call Web services. The details are as follows:

Steps:
1. Download nusoap library from internet.
2. Pass parameter list in your $client->call and enjoy.

<?php
require_once(&#39;./lib/nusoap.php&#39;);
$client = new soapclientnusoap(&#39;http://www.devtrackn.com/webservice/server.php&#39;);
$err = $client->getError();
if ($err) {
  // Display the error
  echo &#39;<p><b>Constructor error: &#39; . $err . &#39;</b></p>&#39;;
  // At this point, you know the call that follows will fail
}

// update_location method parameter
$param = array(
    &#39;device_number&#39;   => &#39;9910948357&#39;,
    &#39;latitude&#39;     => &#39;40.727757&#39;,
    &#39;longitude&#39;     => &#39;-73.984366&#39;,
    &#39;battery_status&#39;  => &#39;30&#39;
  );
// user_action method parameter
$param2 = array(
    &#39;device_number&#39;   => &#39;27ab2026da5213ebd6c95e5fbe50965bdfaddf4b&#39;,
    &#39;latitude&#39;     => &#39;40.727757&#39;,
    &#39;longitude&#39;     => &#39;-73.984366&#39;,
    &#39;user_action&#39;    => &#39;Meeting_Test&#39;
  );
// sos method parameter
$param3 = array(
    &#39;device_number&#39;   => &#39;9910948357&#39;,
    &#39;latitude&#39;     => &#39;40.727757&#39;,
    &#39;longitude&#39;     => &#39;-73.984366&#39;,
  );
//$result = $client->call(&#39;update_location&#39;, $param);
//$result = $client->call(&#39;user_action&#39;, $param2);
//$result = $client->call(&#39;sos&#39;, $param3);
$result = $client->call(&#39;user_entity_status&#39;, array(&#39;device_number&#39; => &#39;27ab2026da5213ebd6c95e5fbe50965bdfaddf4b&#39;));
////////////////////////////////////////////////////////

// Check for a fault
if ($client->fault) {
  echo &#39;<p><b>Fault: &#39;;
  print_r($result);
  echo &#39;</b></p>&#39;;
} else {
  // Check for errors
  $err = $client->getError();
  if ($err) {
    // Display the error
    echo &#39;<p><b>Error: &#39; . $err . &#39;</b></p>&#39;;
  } else {
    // Display the result
    echo "<pre class="brush:php;toolbar:false">";
    print_r($result);
    echo "

"; } } echo '

Request
