(no version information, might be only in CVS)SoapServer->setPersistence() -- Sets persistence mode of SoapServer
This function allows saving data between requests in a PHP session. It works only with a server that exports functions from a class with SoapServer->setClass().
Note: The persistence SOAP_PERSISTENCE_SESSION makes persistent only object of given class, but not the class static data. You may use $this->bar instead of self::$bar.
