Which of the following is better to catch an error when calling a web service us开发者_如何转开发ing SoapClent?

try {
  $response = $client->SomeSoapRequest();
}
  catch(SoapFault $e){
}

Or:

try {
  $response = $client->SomeSoapRequest();
}
  catch(SoapFault $e){
}
  catch(Exception $e){

Just catch Exception; this will also catch SoapFault. If you need to know the difference, you can check the type of the object received. Exception will also catch other non-soapfault exceptions, which you should be doing anyway. So, the answer is: the second one.
