SoapServer::setPersistence

(PHP 5, PHP 7, PHP 8)

SoapServer::setPersistence — Sets SoapServer persistence mode

说明

public SoapServer::setPersistence(int $mode): void

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().

注意:

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.

注意:

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.

参数

mode

One of the SOAP_PERSISTENCE_* 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.

返回值

没有返回值。

示例

示例 #1 SoapServer::setPersistence() example

<?php
class MyFirstPersistentSoapServer {
private $resource; // (Such as PDO, mysqli, etc..)
public $myvar1;
public $myvar2;

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