quot;useSOAPquot; => quot;1.2quot;,
quot;useWSAquot; => TRUE,
quot;policyquot; => $wspolicy,
quot;securityTokenquot; => $sec_token));

Mapping
 Enables mapping a REST API into PHP easily and naturally

function echoFunction($inMessage) {

$outMessage = new WSMessage($inMessage->str);
return $outMessage;
}

$operations = array(quot;echoStringquot; => quot;echoFunctionquot;);
$restmap = array (quot;echoStringquot;=>array(quot;HTTPMethodquot;=>quot;GETquot;, quot;RESTLocationquot;=> quot;echoStringquot;));

$service = new WSService(array(quot;operationsquot; => $operations, quot;RESTMappingquot;=>$restmap));
$service->reply();

quot;dbhostquot; => quot;localhostquot;);

$inputFormat = array(quot;employeeByNumberquot; => quot;INTquot;);

$outputFormat = array(quot;resultElementquot; => quot;employeesquot;,

$sql = quot;SELECT lastName,firstName,email FROM Employees WHERE employeeNumber=?quot;;

$operations = array(quot;employeesByNumberquot; =>
array(quot;inputFormatquot; => $inputFormat, quot;outputFormatquot; => $outputFormat, quot;sqlquot; => $sql));

$my_data_service = new DataService(array(quot;configquot; => $config, quot;operationsquot; => $operations));
$my_data_service->reply();
