API request from Specific IP - php

Question

I'm using Ultimate Hosting package of GoDaddy. The account has a static IP and SSL installed. Now when I'm trying to use an API which needs static IP. But scripts are sending requests from random IPs. Please suggest me an way.
My Script
$soap_exception_occured = false;
$wsdl_path = 'http://vrapi.sslwireless.com/?wsdl';
$response = '';
ini_set('soap.wsdl_cache_enabled', '0'); // disabling WSDL cache
try {
$client = new SoapClient($wsdl_path);
}
catch(SoapFault $exception) {
$soap_exception_occured = true;
$response .= '\nError occoured when connecting to the SMS SOAP Server!';
$response .= '\nSoap Exception: '.$exception;
}
I'm using SOAP. Can IP binding help me ?

Answer 1

Assuming you are using curl of php to connect to that API, you should bind each request to your IP:
curl_setopt($ch, CURLOPT_INTERFACE, $myIP);
To bind CURL to a different outgoing network interface or a different IP address, all that is needed is to set the CURLOPT_INTERFACE to the appropriate value before executing the CURL request:

Try this and let me know what happend
$soap_exception_occured = false;
$ipandport = array(
'socket' => array(
'bindto' => 'xx.xx.xx.xx:port',
),
);
$setip = stream_context_create(ipandport);
$wsdl_path = 'http://vrapi.sslwireless.com/?wsdl';
$response = '';
ini_set('soap.wsdl_cache_enabled', '0'); // disabling WSDL cache
try {
$client = new SoapClient($wsdl_path, array('stream_context' => $setip));
}
catch(SoapFault $exception) {
$soap_exception_occured = true;
$response .= '\nError occoured when connecting to the SMS SOAP Server!';
$response .= '\nSoap Exception: '.$exception;
}

This thread will be a not complete without file_get_contents:
$opts = array(
'socket' => array(
'bindto' => 'xx.xx.xx.xx:0',
)
);
$context = stream_context_create($opts);
echo file_get_contents('http://www.example.com', false, $context);
