如何在PHP Soap類上設置成員變量？

Question

我有一個類class.foo.php。 它作為本地類正常運行。 但是，我不能在Soap Call下設置Member Variable。

這是class.foo.php

/**
 * Foo test base on PhpWsdl
 * 
 * @service foo
 */

class Foo {
    public $aMemberVar = 'Original';

    /**
     * setMemberVar
     *
    */
    function setMemberVar(){
        $this->aMemberVar = 'Changed';
    }

    /**
     * getMemberVar
     *
     * @return string return a String 
    */
    function getMemberVar(){
        return $this->aMemberVar;
    }


} 
?>

作為本地課程，

<?php
require_once('class.foo.php');
$t = new Foo();
echo "<br>Before:".$t->getMemberVar();
$t->setMemberVar();
echo "<br>After Set:".$t->getMemberVar();
?>

我得到正確的結果：

Before:Original
After Set:Changed

但是，當我在Soap Client中調用它時。

<?php
ini_set("soap.wsdl_cache_enabled", "0");
$t = new SoapClient('http://188.4.72.11/okmservices/foo.php?WSDL');
echo "<br>Before:".$t->getMemberVar();
$t->setMemberVar();
echo "<br>After Set:".$t->getMemberVar();
?>

結果是意外的，成員變量不會更改：

Before:Original
After Set:Original

我該怎么做才能獲得與本地課程相同的結果？？？

這是基於https://code.google.com/p/php-wsdl-creator/的 php-wsdl-creator的Soap Server代碼。

<?php
require_once('class.foo.php');

// Initialize the PhpWsdl class
require_once('php-wsdl/class.phpwsdl.php');

// Disable caching for demonstration
ini_set('soap.wsdl_cache_enabled',0);   // Disable caching in PHP
PhpWsdl::$CacheTime=0;                  // Disable caching in PhpWsdl

$soap=PhpWsdl::CreateInstance(
    null,                               // PhpWsdl will determine a good namespace
    null,                               // Change this to your SOAP endpoint URI (or keep it NULL and PhpWsdl will determine it)
    './cache',                          // Change this to a folder with write access
    Array(                              // All files with WSDL definitions in comments
        'class.foo.php'
    ),
    null,                               // The name of the class that serves the webservice will be determined by PhpWsdl
    null,                               // This demo contains all method definitions in comments
    null,                               // This demo contains all complex types in comments
    false,                              // Don't send WSDL right now
    false);                             // Don't start the SOAP server right now

$soap->SoapServerOptions = Array(
            'soap_version'  =>  SOAP_1_1,
            'encoding'      =>  'UTF-8',
            'compression'   =>  SOAP_COMPRESSION_ACCEPT);

// Run the SOAP server
if($soap->IsWsdlRequested())            // WSDL requested by the client?
    $soap->Optimize=false;              // Don't optimize WSDL to send it human readable to the browser

$soap->RunServer();                     // Finally, run the server
?>

經過幾天的努力，終於找到了解決方案。 我們需要調用SoapServer-> setPersistence（）來將肥皂服務器設置為持久性模式。

但是php-wsdl-creator不支持此選項。 因此，最簡單的方法是直接修改文件php-wsdl / class.phpwsdl.php。 在直接調用SoapServer-> handle（）方法之前，請先調用setPersistence（）函數。

$this->SoapServer->setPersistence(SOAP_PERSISTENCE_SESSION);
$this->SoapServer->handle();

現在它可以正常工作並獲得預期的結果。

Before:Original
After Set:Changed
