Handling Soap timeouts in PHP

Question

I\'m working on a project where I am verifying information from a user with a SOAP web service. I currently am taking care of errors assuming that I\'m receiving responses from

Answer 1

I used two factors to get my SoapClient extention to throw a nice exception. The message and the time the request took to return. I think the error message "Error Fetching http headers" can also occure in some other cases, therefore the time check.

The following code should be about right

class SoapClientWithTimeout extends SoapClient {
    public function __soapCall ($params, ---) {
        $time_start = microtime(true);
        try {
            $result = parent::__soapCall ($params, ---);
        }
        catch (Exception $e) {
            $time_request = (microtime(true)-$time_start);
            if(
                $e->getMessage() == 'Error Fetching http headers' &&
                ini_get('default_socket_timeout') < $time_request
            ) {
                throw new SoapTimeoutException(
                    'Soap request most likly timed out.'.
                    ' It took '.$time_request.
                    ' and the limit is '.ini_get('default_socket_timeout')
                );
            }

            // E: Not a timeout, let's rethrow the original exception
            throw $e;
        }

        // All good, no exception from the service or PHP
        return $result;
    }
}

class SoapTimeoutException extends Exception {}

I then use SoapClientWithTimeout

$client = new SoapClientWithTimeout();
try {
    $response = $client->SomeSoapRequest();
    var_dump($response);
}
catch(SoapTimeoutException $e){
    echo 'We experienced a timeout! '. $e->getMessage();
}
catch(Exception $e) {
    echo 'Exception: '.$e->getMessage();
}

To debug your service timing out. Add the following line before calling the service

ini_set('default_socket_timeout', 1);
