SoapServer->setPersistence()

(PHP 5 >= 5.1.2)

SoapServer->setPersistence() Versetzt einen SoapServer in den Persistenz-Modus

Beschreibung

void SoapServer::setPersistence ( int $mode )

Diese Funktion ermöglicht das Zwischenspeichern von Daten während den Anfragen in der PHP-Session. Es funktioniert nur, wenn der Server die Funktionen von einer gesetzten Klasse exportiert, die durch SoapServer->setClass() gesetzt wurde.

Parameter-Liste

mode

Eine der SOAP_PERSISTENCE_XXX Konstanten.

Rückgabewerte

Es wird kein Wert zurückgegeben.

Beispiele

Beispiel #1 Beispiele

<?php

$server
->setPersistence(SOAP_PERSISTENCE_SESSION);

$server->setPersistence(SOAP_PERSISTENCE_REQUEST);

?>

Hinweis: SOAP_PERSISTENCE_SESSION macht nur Objekte der definierten Klassen persistent. Statische Daten werden nicht berücksichtigt, daher sollte immer $this->bar anstelle von self::$bar genutzt werden.

I want to give one example for the order of commands if you want to use a class in persistence mode.

<?php
// 1. class definition or include
class UserService
{
    public function
__construct() { }
}

// 2. start the session after defining or including the class!!
session_start();

// 3. instanciate the server
$server = new SoapServer(null, array("something"));

// 4. set the class to use
$server->setClass('UserService');

// 5. set persistance mode
$server->setPersistence(SOAP_PERSISTENCE_SESSION);

// 6. handle the request
$server->handle();
?>

When using "SoapServer::setPersistence( SOAP_PERSISTENCE_SESSION )", you apparently MUST include the class that was used in "SoapServer::setClass()" BEFORE any "session_*" commands.

I found this out using "__autoload()" and a whole lot of "syslog()"; it kept failing to include the class that I was using for my soap server, but that class is ONLY ever referenced by the page itself, and even then only for the purposes of setting the class for the soap server; none of my code would ever cause it to autoload.  The problem was that I was including my session-handling code first.

If the session gets started BEFORE the page defines the class definition, then persistence CANNOT happen.

The order should be:
1. Include the class for use with the soap server.
2. Start up your session.
3. Set up your soap server.
4. Handle your soap request.

setPersistence works only for a single instance of service class.

To use multiple instance of services objects, you need to instantiate the classes into objects and use an undocumented SoapServer's method - setObject() to add the service object into the SoapServer object, and handle the service object persistence with $_SESSION instead.

For example:

$ServiceObjects = array()
$ServiceObjects[0] = new ServiceClass1();
$ServiceObjects[1] = new ServiceClass2();
$ServiceObjects[2] = new ServiceClass3();

$_SESSION['ServiceClass1'] = $ServiceObjects[0];
$_SESSION['ServiceClass2'] = $ServiceObjects[1];
$_SESSION['ServiceClass3'] = $ServiceObjects[2];

...

$Servers = array()
for ( $i = 0; $i < count($ServiceObjects); i++)
{
  $s = new SoapServer($wsdl);
  $s->setObject($ServiceObject[$i]);
  $Servers[] = $s;
}

...

$Server[$i]->handle()

I found that using both modes (SOAP_PERSISTENCE_SESSION and SOAP_PERSISTENCE_REQUEST) cannot be used simultaniously. Because it didn't work at once, I started experimenting by using different settings and as stated below in the comments, "...also use SOAP_PERSISTENCE_REQUEST to save objects between requests" led me to think it was nessecary to use both modes. Well, it might for others, be but for me it turned out a day of freaking out ;) (trying all kinds of session stuff, etc etc).
Also, if persistence doesn't work, please check if session_start() is called somewhere in the script and try not to call it twice or whatsoever: it won't work...

attention, if you are using a custon session-handler, the SOAP_PERSISTENCE_SESSION methode will use the files-session handler and not your custom handler. also use SOAP_PERSISTENCE_REQUEST to save objects between requests

I had some issues getting session persistence (SOAP_PERSISTENCE_SESSION) to work. I finally got it working after setting session.auto_start=0, and then only calling session_start() in the script containing the SoapServer. Maybe this is obvious, but took me a bit to figure it out.

I only tried it with session.use_cookies=1, so if the settings above don't work for you, make sure cookies are enabled, though it may work without the need for cookies.

Always remember to place the "setPersistence" method before the handle method, otherwise it won't work.  It sounds obvious, but it's still a very common mistake, since no errors are shown.
