A continuación un ejemplo sencillo en php que consume un
Web Service en este caso de Navision (aunque eso es lo de menos):
<?php
define('USERPWD','192.168.0.150\Administrador:xxx'); // Sustituir xxx por la contraseña del servidor
include("NTLMStream.php");
include("NTLMSoapClient.php");
stream_wrapper_unregister('http');
stream_wrapper_register('http','NTLMStream') or die("Fallo al registrar protocolo");
$pageURL = 'http://192.168.0.150:7047/dynamicsnav/ws/Autoequip/Codeunit/NEUMALIAWS'; // El Web Service
$params = array();
$params["param1"] = "2855519MDIAMARISVR"; // param1 es el nombre el primer parámetro.
$params["param2"] = "2";
$params["param3"] = "1024";
$client = new NTLMSoapClient($pageURL);
stream_wrapper_restore('http');
$result = $client->ImportPedNeumalia($params); // El método del Web Service
$numped = $result->return_value;
echo 'Pedido creado: '.$numped;
die();
?>

NOTA: Debemos asegurarnos que la extensión php_soap está habilitada; de lo contrario se producirá un error similar a este:
En el caso de tener WAMP como servidor de Apache/PHP/MySQL, esta opción la encontraremos dentro de las PHP_Extensions.
