本文实例讲述了PHP使用NuSOAP调用Web服务的方法。分享给大家供大家参考。具体如下：

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

<?phprequire_once('./lib/nusoap.php');$client = new soapclientnusoap('http:///webservice/server.php');$err = $client->getError();if ($err) { // Display the error echo '<p><b>Constructor error: ' . $err . '</b></p>'; // At this point, you know the call that follows will fail}////////////////////////////////////////////////////////////////////////////////////////////////////////////////// update_location method parameter$param = array( 'device_number' => '9910948357', 'latitude' => '40.727757', 'longitude' => '-73.984366', 'battery_status' => '30' );// user_action method parameter$param2 = array( 'device_number' => '27ab2026da5213ebd6c95e5fbe50965bdfaddf4b', 'latitude' => '40.727757', 'longitude' => '-73.984366', 'user_action' => 'Meeting_Test' );// sos method parameter$param3 = array( 'device_number' => '9910948357', 'latitude' => '40.727757', 'longitude' => '-73.984366', );//$result = $client->call('update_location', $param);//$result = $client->call('user_action', $param2);//$result = $client->call('sos', $param3);$result = $client->call('user_entity_status', array('device_number' => '27ab2026da5213ebd6c95e5fbe50965bdfaddf4b'));////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Check for a faultif ($client->fault) { echo '<p><b>Fault: '; print_r($result); echo '</b></p>';} else { // Check for errors $err = $client->getError(); if ($err) { // Display the error echo '<p><b>Error: ' . $err . '</b></p>'; } else { // Display the result echo "<pre>"; print_r($result); echo "</pre>"; }}echo '<h2>Request</h2>';echo '<pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';echo '<h2>Response</h2>';echo '<pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';?>

希望本文所述对大家的php程序设计有所帮助。
