How to create php SOAP Server functions using WSDL?

I want to create PHP SOAP Server, but don't understand how to do it correctly. So below is the server.php file:

<?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' => SOAP_1_2,
    'style' => SOAP_RPC,
    'use' => SOAP_LITERAL
));
$server->setClass('NewOperation');
$server->handle();

The client.php file:

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

The wsdl file:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

Zipped all files

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

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...', 'http://localhos...', 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

Solution

  • Finally i figure out how it's works.

    Now my wsdl in eclipse looks like: enter image description here

    And Calculator.wsdl:

        <?xml version="1.0" encoding="UTF-8" standalone="no"?>

    My server.php:

            <?php
    ini_set("soap.wsdl_cache_enabled", "0");

    class Server{

        protected $class_name = '';

        public function __construct($class_name)
        {
            $this->class_name = $class_name;
        }
        public function AuthHeader($Header)
        {
            //if($Header->username == 'foo' && $Header->password == 'bar')
            //   $this->authenticated = true;

        }

        public function log($method_name,$data)
        {
            $filename = 'log.txt';
            $handle = fopen($filename, 'a+');
            fwrite($handle, date("l dS of F Y h:i:s A").' - '.$_SERVER['REMOTE_ADDR']."\r\n".$method_name."\r\n".print_r($data,true));
            fclose($handle);
        }

        public function __call($method_name, $parameters)
        {
            $this->log($method_name,$parameters); //  log
            //if($arguments[0]!=AUTH) return 'Authorization required'; // auth check
            if(!method_exists($this->class_name, $method_name )) return 'Method '.$method_name.' not found'; // methot exist check
            return call_user_func_array(array($this->class_name, $method_name ), $parameters); //call method
        }
    }


    class Calculator {
        public function Average ($parameters)
        {
            $num1 = $parameters->num1;
            $num2 = $parameters->num2;

            return self::AverageResponse(($num1 + $num2) / 2);
        }

        public function AverageResponse ($message)
        {
            return ['Result' => $message];
        }
    }

    class in {

    }

    $Service = new Server('Calculator');
    $classmap=[
        'in' => 'in'
    ];
    $server = new SOAPServer('http://localhost:9080/soap-websiteservice-wsdl/Calculator.wsdl', array(
        'soap_version' => SOAP_1_2,
        'style' => SOAP_RPC,
        'use' => SOAP_LITERAL,
        'classmap'=>$classmap
    ));
    $server->setObject($Service);
    //$server->setClass('Calculator');
    $server->handle();

    client.php

            <?php
    // client.php
    $options = array(
        'trace' => true
    );
    $client = new SOAPClient('http://localhost:9080/soap-websiteservice-wsdl/server.php?wsdl', $options);
    var_dump($client->Average(['num1' => 10, 'num2' => 6])->Result);

    So i tested with Virtual Studio. So i created form: enter image description here

    Created Web service reference: localhost. And my button click event looks like:

            using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using System.Windows.Forms;

    namespace WindowsFormsApplication1
    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }

            private void button1_Click(object sender, EventArgs e)
            {
                localhost.Calculator client = new localhost.Calculator();

                string returnString;

                returnString = client.Average(10,8);
                label1.Text = returnString;
            }
        }
    }
