Use Webservice in PHP environement

Hello us !

I want to use webservice CLS in Netbeans and use PHP development tool.

I create this

try {
    $wsdl_url = '[URL].ClassPatientServices.cls?WSDL=1&CacheUserName=[USER]&CachePassword=[PWD];
    $client = new SOAPClient($wsdl_url);
    $params = array(
        'ClsINOUTContext' => array('AccesCode'=>'CWP','username'=>''),
        'strINPatientIPP' => "91005573",
        'ClsOUTInfosPatient' => "patient",
    );
    $return = $client->GetPatientInfo($params);
    print_r($return);
} catch (Exception $e) {
    echo "Exception occured: " . $e;
}

Can you help me to use this webservice ?
