Sets SoapServer persistence mode

(PHP 5 >= 5.1.2)

SoapServer::setPersistenceSets SoapServer persistence mode


public void SoapServer::setPersistence ( int $mode )

This function allows changing the persistence state of a SoapServer object between requests. This function allows saving data between requests utilizing PHP sessions. This method only has an affect on a SoapServer after it has exported functions utilizing SoapServer::setClass().


The persistence of SOAP_PERSISTENCE_SESSION makes only objects of the given class persistent, but not the class static data. In this case, use $this->bar instead of self::$bar.


SOAP_PERSISTENCE_SESSION serializes data on the class object between requests. In order to properly utilize resources (e.g. PDO), __wakeup() and __sleep() magic methods should be utilized.

Список параметров


One of the SOAP_PERSISTENCE_XXX constants.

SOAP_PERSISTENCE_REQUEST - SoapServer data does not persist between requests. This is the default behavior of any SoapServer object after setClass is called.

SOAP_PERSISTENCE_SESSION - SoapServer data persists between requests. This is accomplished by serializing the SoapServer class data into $_SESSION['_bogus_session_name'], because of this session_start() must be called before this persistence mode is set.

Пример #1 SoapServer::setPersistence() example

class MyFirstPersistentSoapServer {
$resource// (Such as PDO, mysqli, etc..)
public $myvar1;

     public function 
__construct() {
$this->__wakeup(); // We're calling our wakeup to handle starting our resource

     public function 
__wakeup() {
$this->resource CodeToStartOurResourceUp();

     public function 
__sleep() {
// We make sure to leave out $resource here, so our session data remains persistent
         // Failure to do so will result in the failure during the unserialization of data
         // on the next request; thus, our SoapObject would not be persistent across requests.
return array('myvar1','myvar2');

 try {
$server = new SoapServer(null, array('uri' => $_SERVER['REQUEST_URI']));
// setPersistence MUST be called after setClass, because setClass's
     // behavior sets SESSION_PERSISTENCE_REQUEST upon enacting the method.
 } catch(
SoapFault $e) {
error_log("SOAP ERROR: "$e->getMessage());
