Changing outgoing IP for NuSOAP

Question

I got a cPanel hosting with Dedicated IP address,

the outgoing IP however is still the shared IP of the host provider (which should be).

I need to do some outgoing calls using nusoap with that Dedicated IP:

$nusoap = new nusoap_client("https://URL/");
$call   = $nusoap->call(...);

How can I change the outgoing IP here with NuSOAP?

I know how to do it with cURL (curl_setopt($ch, CURLOPT_INTERFACE, $website_ip);), but how to achieve same thing with this method. been working on it for hours now, server side and php side but still couldn't figure it out.

Answer 1

1) Use PHP's SoapClient and not NuSoap (it's been available since PHP5, and hopefully you're not still using PHP4 as it's very out-of-support and the NuSoap library itself has not been updated for over 3 years).

2) You can pass a stream context to your SoapClient constructor that has a bindto options set.

Credits: Taken straight from Is it possible to specify the outgoing network interface to use for a PHP SoapClient?

$opts = array(
    'socket' => array(
        'bindto' => '192.168.0.100:0',
     ),
);

$ctx = stream_context_create($opts);

$client = new SoapClient('the.wsdl', array('stream_context' => $ctx));

Edit: If you must use NuSoap, have you tried

nusoap_client->setCurlOption(CURLOPT_INTERFACE, $website_ip)

From the source:

function setCurlOption($option, $value) {
    $this->debug("setCurlOption option=$option, value=");
    $this->appendDebug($this->varDump($value));
    $this->curl_options[$option] = $value;
}
