How to create php SOAP Server functions using WSDL?
<p>I want to create PHP SOAP Server, but don't understand how to do it correctly. So below is the <strong>server.php</strong> file:</p>

<pre><code>&lt;?php

class NewOperation {
    public function NewOperation()
    {

    }
}

ini_set("soap.wsdl_cache_enabled", "0");
$server = new SOAPServer('http://localhost:9080/soap-websiteservice-        wsdl/CalculatorService.wsdl', array(
    'soap_version' =&gt; SOAP_1_2,
    'style' =&gt; SOAP_RPC,
    'use' =&gt; SOAP_LITERAL
));
$server-&gt;setClass('NewOperation');
$server-&gt;handle();
</code></pre>

<p>The <strong>client.php file</strong>:</p>

<pre><code>&lt;?php
// client.php
$options = array(
    'trace' =&gt; true
);
$client = new SOAPClient('http://localhost:9080/soap-websiteservice-    wsdl/server.php?wsdl', $options);
var_dump($client-&gt;NewOperation());
</code></pre>

<p>The <strong>wsdl file</strong>:</p>

<pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="no"?&gt;
&lt;wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"     xmlns:tns="http://localhost:9080/soap-websiteservice-wsdl/CalculatorService/"     xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"     xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="CalculatorService"     targetNamespace="http://localhost:9080/soap-websiteservice-    wsdl/CalculatorService/"&gt;

<p>I created WSDL file with Eclipse web service XML editor. Now I do not know how to create functions. I get the following error: </p>

<blockquote>
  <p>Fatal error: Uncaught SoapFault exception: [HTTP] Not Found in C:\wamp\www\soap-websiteservice-wsdl\client.php:7 Stack trace: #0 [internal function]: SoapClient->__doRequest('http://localhos...', '<a href="http://localhos" rel="nofollow noreferrer">http://localhos</a>...', 1, 0) #1 C:\wamp\www\soap-websiteservice-wsdl\client.php(7): SoapClient->__call('NewOperation', Array) #2 C:\wamp\www\soap-websiteservice-wsdl\client.php(7): SoapClient->NewOperation() #3 {main} thrown in C:\wamp\www\soap-websiteservice-wsdl\client.php on line 7</p>
