Clean way to throw php exception through jquery/ajax and json

Question

Is there a clean, easy way to throw php exceptions through a json response jquery/ajax call.

Answer 1

Facebook do something in their PHP SDK where they throw an exception if a HTTP request failed for whatever reason. You could take this approach, and just return the error and exception details if an exception is thrown:

 $results
    ));
}
catch (Exception $e) {
    echo json_encode(array(
        'error' => array(
            'code' => $e->getCode(),
            'message' => $e->getMessage()
        )
    ));
}

You can then just listen for the error key in your AJAX calls in JavaScript:
