PHP Webservices SOAP, struttura file wsdl

[w_t]

Salve,
stò affrontando per la prima volta i web services SOAP in PHP, stò cercando di capire le basi e la struttura del file ".wsdl", ho trovato cosi tanti esempi e testi che non so a quale affidarmi, per ogni esempio la struttura cambia, i tag cambiano, insomma è tutto diverso...

Vi chiedo una mano per scegliere una guida dove imparare correttamente come realizzare un web services in PHP e SOAP, escludendo "nusoap e soap rest".

Se ci sono più modi di procedere vorrei imparare quello migliore a livello di sicurezza.

Grazie molte.

Seguo.. è un argomento che mi interessa molto e su cui ho più volte perso la testa cercando di capirci qualcosa..


Saluti G.G.

Cosa c'è di sbagliato in questo wsdl ?? Funziona ma non credo assolutamente che sia scritto come si deve.

Questo è il server:

ini_set('soap.wsdl_cache_enabled', 0);

    {
        return $my_value_2;
    }
}

$Service = new MyClass();

$server = new SoapServer("ws.wsdl");
$server->setObject($Service);
$server->handle();

Questo è il client:

ini_set('soap.wsdl_cache_enabled', 0);
ini_set('soap.wsdl_cache_ttl', 0);

$wsdl = 'http://127.0.0.1/ws_soap/server.php/method?WSDL';

$options = array(
                'uri'=>'http://schemas.xmlsoap.org/soap/envelope/',

                );

$objClient = new SoapClient($wsdl, $options);

        $resp2 = $objClient->MyFunction_2(" sono Mario");
       
        echo $resp1.$resp2;
    }
}
catch(SoapFault $ex)
{
    echo var_dump($ex);
