[PHP/XML] Webservices SOAP, struttura file wsdl

[race2]

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.

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);

class MyClass
{
public function MyFunction_1($my_value_1)
{
return $my_value_1;
}

public function MyFunction_2($my_value_2)
{
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/',
'style'=>SOAP_RPC,
'use'=>SOAP_ENCODED,
'soap_version'=>SOAP_1_1,
'cache_wsdl'=>WSDL_CACHE_NONE,
'connection_timeout'=>15,
'trace'=>true,
'encoding'=>'UTF-8',
'exceptions'=>true,
);

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

try
{
if(isset($objClient))
{
$resp1 = $objClient->MyFunction_1("Ciao ");
$resp2 = $objClient->MyFunction_2(" sono Mario");

echo $resp1.$resp2;
}
}
catch(SoapFault $ex)
{
echo var_dump($ex);
}
