将 SoapClient 请求绑定到特定 IP

Question

我需要实现一个网络服务，要求我在具有一堆不同 IP 的机器SoapServer上使用特定 IP 发送数据。SoapClient问题是，如何强制 PHP 使用这个特定的 IP 发送该请求？

关于 SOAP 的 PHP 文档确实很差。

谢谢。

通过 halfdan 的回答，我能够解决这个问题，所以我发布了一个结果片段：

protected function load_ws() {
    if ($this->ws == null) { // load webservice

        ini_set("soap.wsdl_cache_enabled", 0);
        ini_set("allow_url_fopen", 1);

        try {
            if ($this->context == null) // load stream context socket
                $this->context = stream_context_create(array(
                    "socket" => array(
                        "bindto" => te_auth_ip.":0"
                    )
                ));

            $this->ws = new SoapClient($this->wsdl_path, array(
                "soap_version" => SOAP_1_1,
                "style" => SOAP_RPC,
                "use" => SOAP_ENCODED,
                "authentication" => SOAP_AUTHENTICATION_BASIC,

                "login" => te_login,
                "password" => te_pass,

                "encoding" => "UTF-8",
                "trace" => true,
                "exceptions" => true,
                "compression" => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP,
                "connection_timeout" => te_timeout,
                "stream_context" => $this->context
            ));

        } catch (SoapFault $fault) {
            $this->error($fault, "LOAD");
        }

    }
}

这应该有效（参见#60004）：

$options = array('socket' => array('bindto' => 'www.xxx.yyy.zzz:port'));
$context = stream_context_create($options);
$soap = new SoapClient($wsdl, array('location'=>'http://...','uri' => '...','stream_context' => $context));

我同意文档应包含此选项。
