Methods

__construct(int $code, array $headers, string $body = null, string $version = '1.1', string $message = null) : void

HTTP response constructor

In most cases, you would use Zend_Http_Response::fromString to parse an HTTP response string and create a new Zend_Http_Response object. NOTE: The constructor no longer accepts nulls or empty values for the code and headers and will throw an exception if the passed values do not form a valid HTTP responses. If no message is passed, the message will be guessed according to the response code.
