Batch request function - Manage response / request relationship

[Matt J]

I have been trying to use the batch feature to download a number of image resources. I need to understand which requests have had a good response (so that they can be processed further) and which have failed (for error logging).

I have read extensively on guide (Though rather slim on detail):

http://guzzle.readthedocs.org/en/latest/clients.html

Plus forums:

Feature added here: https://groups.google.com/forum/#!msg/guzzle/6lo0e205zZ4/suQo7cUU09YJ

This solution looks interesting but uses SendAll() which i have seen no reference to in Guzzle 4 docs?

The functions getSuccessful() and getFailures() look interesting but provide no way to identify which request each response is from

If i use the following on a bad result:

try{

        $result2 = $results->getResult($requests[1]);

        echo "Result2: " . $result2->getStatusCode();

    } catch(Exception $e){

            if($e->getMessage()){

                    $error = $e->getMessage();

            } else {

                    $error = 'Generic exception caught';

            }

        

            echo "Error: $error";

    }

I get an error that isnt caught, plus the above doesnt feel like a good way to manage the success/fail process.

Is there a recommended pattern for this?
