WebService banguat.gob.gt - php

Question

Thank you all in advance for the help:
I have this code:
require_once('include/nusoap/lib/nusoap.php');
$soapclient = new soapclient('http://www.banguat.gob.gt/variables/ws/TipoCambio.asmx');
print_r( $soapclient->call( 'TipoCambioDia' ) );
and gives me this error:Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://www.banguat.gob.gt/variables/ws/TipoCambio.asmx' : Premature end of data in tag html line 3 in C:\xampp\htdocs\cambio_moneda\cambio_moneda.php:3 Stack trace: #0 C:\xampp\htdocs\cambio_moneda\cambio_moneda.php(3) : SoapClient->SoapClient('http://www.bang...') #1 {main} thrown in C:\xampp\htdocs\cambio_moneda\cambio_moneda.php on line 3
Then I tried with this code:
require_once('include/nusoap/lib/nusoap.php');
$soapclient = new soapclient();
$result = $soapclient->call( 'TipoCambioDia' , array(), "http://www.banguat.gob.gt/variables/ws/TipoCambio.asmx?op=TipoCambioDia", "http://www.banguat.gob.gt/variables/ws/TipoCambio.asmx?op=TipoCambioDia");
print_r( $result );
And I get this error results:Fatal error: Uncaught SoapFault exception: [Client] SoapClient::SoapClient(): Invalid parameters in C:\xampp\htdocs\cambio_moneda\cambio_moneda.php:3 Stack trace: #0 C:\xampp\htdocs\cambio_moneda\cambio_moneda.php(3) : SoapClient->SoapClient() #1 {main} thrown in C:\xampp\htdocs\cambio_moneda\cambio_moneda.php on line 3
What I want to accomplish is to get the exchange rate plus the date and store it in a variable
Thanks to all

The reason for the fatal error is that the URL you are using to create $soapclient is not a WSDL file. You will need to change it (note the ?WSDL in the URL):
$soapclient = new soapclient('http://www.banguat.gob.gt/variables/ws/TipoCambio.asmx?WSDL');
Next, to get "TipoCambioDia" call, you need to use it directly, i.e.:
$soapclient->TipoCambioDia()
Doing this will return in a stdObject:
stdClass Object
(
[TipoCambioDiaResult] => stdClass Object
(
[CambioDolar] => stdClass Object
(
[VarDolar] => stdClass Object
(
[fecha] => 30/01/2015
[referencia] => 7.65538
)
)
[TotalItems] => 1
)
)
