SOAP Client In CodeIgniter using NuSOAP PHP Toolkit

Date July 30, 2015 Author By Category PHP Frameworks

To create SOAP client in CodeIgniter, it is better to use NuSOAP (SOAP Toolkit for PHP).

Download NuSOAP Toolkit from this URL: Download

Below are the steps to create SOAP client in CodeIgniter using NuSOAP PHP Toolkit.

Step 1: After downloading NuSOAP toolkit, copy “lib” and “nusoap” folder in “application/library/” folder.

Step 2: Create one library file say “nusoap_library.php” in “application/library” folder and copy and paste below given code in “application/library/nusoap_library.php” file. It just includes “nusoap.php” library file from “lib” folder.

    class Nusoap_library
    {
       function Nusoap_library()
       {
           require_once('lib/nusoap'.EXT);
       }
    }

Step 3: SOAP request function. Copy and paste below given function to “application/library/nusoap_library.php” file.

function soaprequest($api_url, $api_username, $api_password, $service, $params)
{
	if ($api_url != '' && $service != '' && count($params) > 0)
	{
		$wsdl = $api_url."?wsdl";
		$client = new nusoap_client($wsdl, 'wsdl');
		$client->setCredentials($api_username,$api_password);
		$error = $client->getError();
		if ($error)
		{
			echo "\nSOAP Error\n".$error."\n";
			return false;
		}
		else
		{
			$result = $client->call($service, $params);
			if ($client->fault)
			{
				print_r($result);
				return false;
			}
			else
			{
				$result_arr = json_decode($result, true);
				$return_array = $result_arr['result'];
				return $return_array;
			}
		}
	}
}

Step 4: To send SOAP request to SOAP web service method, we need to load NuSOAP library in Controller where we want to use SOAP client.

$this->load->library("Nusoap_lib", "");

Step 5: SOAP service call in Controller

$api_url = WEBSERVICE_URL; // ex. http://www.example.com/index.php/soapserver
$api_username = AUTHENTICATION USERNAME;
$api_password = AUTHENTICATION PASSWORD;
$service = "addnumbers"; // from my POST <a href="https://www.php-guru.in/2013/soap-server-in-codeigniter-using-nusoap-library/" target="_blank">SOAP Server In CodeIgniter using NuSOAP PHP Toolkit</a>
$params = array('a' => 5, 'b' => 10); // input parameters to "addnumbers" medhod
if ($api_url != '')
{
	$result = $this->nusoap_lib->soaprequest($api_url, $api_username, $api_password, trim($service), $params);
	if (is_array($result) && count($result) > 0)
	{
		print_r($result);
	}
}

Hope this post will help you !!!
