Steps to invoke on SOAP Web Service in PHP:
To invoke SOAP Web Service, you need to aware about the following items:
1) WSDL/WADL location of your Web Service to invoke from PHP.
2) Actions available in the respective Web Service.
3) Parameters are required to invoke Web Service with the respective actions in it.
4) Optional, If its have any header information like authentication / namespace of Web Service.
Simple Web Service Method:
[php]
$soapClient = new SoapClient("https://test.soapws.com/globalweather.php?wsdl");
<pre>// Setup the parameters of the action
$requestParams = array(
‘CityName’ => ‘Chennai’,
‘CountryName’ => ‘India’
);
// Call Soap action
$soapResponse = $soapClient->GetWeather($requestParams);</pre>
// Soap Response
print_r($soapResponse);
[/php]
As the result of invoking the Web Service, you will get response as stdClass Object. Now you can easily iterate the result-sets and display it however you like.
Headers with Web Service Method:
[php]
$soapClient = new SoapClient("https://test.soapws.com/globalweather.php?wsdl");
// Setup SoapHeader parameters
$headerParams = array(
‘Username’ => ‘username’,
‘Password’ => ‘password’);
$soapHeaders = new SoapHeader(‘https://test.soapws.com/weather’, ‘UserCredentials’, $headerpParams);
// Prepare Soap Client with headers
$soapClient->__setSoapHeaders(array($soapHeaders));
// Setup the parameters of the action
$requestParams = array(
‘CityName’ => ‘Chennai’,
‘CountryName’ => ‘India’
);
// Call Soap action
$soapResponse = $soapClient->GetWeather($requestParams);
// Soap Response
print_r($soapResponse);
[/php]
As the result of invoking Web Service, you will get the response from the Web Service as stdClass Object.
To verify the SOAP Client response you can use SOAPUI tool.
