catch error from a SOAP? - php

Question

How to catch an error from a SOAP?
How can I avoid the fatal error and convert it to my own error.. In this example it's a SERVER_BUSY
code
class Validate_vatno {
private $client = null;
private $options = array(
'debug' => false
);
public function __construct(){
$this->client = new SoapClient('http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl', array('trace' => true));
}
public function check($country, $vatno){
$result = $this->client->checkVat(array(
'countryCode' => $country,
'vatNumber' => $vatno
));
if(!empty($this->options['debug'])){
echo '<pre>'.htmlentities($this->client->__getLastResponse()).'</pre>';
}
if($result->valid){
list($denomination, $name) = explode(' ', $result->name, 2);
return array(
'denomination' => utf8_decode($denomination),
'name' => ucwords(utf8_decode($name)),
'address' => ucwords(utf8_decode($result->address)),
);
}
else{
return array();
}
}
}
$vatValidation = new Validate_vatno();
if($return = $vatValidation->check('DK', 33214944)){
echo '<h1>valid one!</h1>';
echo 'denomination: ' . $return['denomination']. '<br/>';
echo 'name: ' . $return['name']. '<br/>';
echo 'address: ' . $return['address']. '<br/>';
}
else{
echo '<h1>Invalid VAT</h1>';
}
error
Fatal error: Uncaught SoapFault exception: [soapenv:Server] { 'SERVER_BUSY' } in /var/www/
