3 namespace Psr\Http\Message;
6 * Representation of an outgoing, server-side response.
8 * Per the HTTP specification, this interface includes properties for
9 * each of the following:
12 * - Status code and reason phrase
16 * Responses are considered immutable; all methods that might change state MUST
17 * be implemented such that they retain the internal state of the current
18 * message and return an instance that contains the changed state.
20 interface ResponseInterface extends MessageInterface
23 * Gets the response status code.
25 * The status code is a 3-digit integer result code of the server's attempt
26 * to understand and satisfy the request.
28 * @return int Status code.
30 public function getStatusCode();
33 * Return an instance with the specified status code and, optionally, reason phrase.
35 * If no reason phrase is specified, implementations MAY choose to default
36 * to the RFC 7231 or IANA recommended reason phrase for the response's
39 * This method MUST be implemented in such a way as to retain the
40 * immutability of the message, and MUST return an instance that has the
41 * updated status and reason phrase.

45 * @param int $code The 3-digit integer result code to set.
46 * @param string $reasonPhrase The reason phrase to use with the
47 * provided status code; if none is provided, implementations MAY
48 * use the defaults as suggested in the HTTP specification.
50 * @throws \InvalidArgumentException For invalid status code arguments.
52 public function withStatus($code, $reasonPhrase = '');
55 * Gets the response reason phrase associated with the status code.
57 * Because a reason phrase is not a required element in a response
58 * status line, the reason phrase value MAY be null. Implementations MAY
59 * choose to return the default RFC 7231 recommended reason phrase (or those
60 * listed in the IANA HTTP Status Code Registry) for the response's

65 * @return string Reason phrase; must return an empty string if none present.
