Class Response
Implements methods for HTTP responses.
All of the following examples assume that $response is an
instance of this class.
Get header values
Header names are case-insensitive, but normalized to Title-Case when the response is parsed.
$val = $response->header('content-type');Will read the Content-Type header. You can get all set headers using:
$response->header();You can also get at the headers using object access. When getting headers with object access, you have to use case-sensitive header names:
$val = $response->headers['Content-Type'];Get the response body
You can access the response body using:
$content = $response->body();You can also use object access:
$content = $response->body;If your response body is in XML or JSON you can use special content type specific accessors to read the decoded data. JSON data will be returned as arrays, while XML data will be returned as SimpleXML nodes:
// Get as xml
$content = $response->xml
// Get as json
$content = $response->jsonIf the response cannot be decoded, null will be returned.
Check the status code
You can access the response status code using:
$content = $response->statusCode();You can also use object access:
$content = $response->code;Constants

Method Detail
__construct() ¶ public
__construct(array $headers = [], string $body = '')Constructor
Parameters
-
array$headers optional Unparsed headers.
-
string$body optional The response body.
__get() ¶ public
__get(string $name): mixedRead values as properties.
Parameters
-
string$name Property name.
Returns
mixed__isset() ¶ public
__isset(string $name): boolisset/empty test with -> syntax.
Parameters
-
string$name Property name.
Returns
bool_decodeGzipBody() ¶ protected
_decodeGzipBody(string $body): stringUncompress a gzip response.
Looks for gzip signatures, and if gzinflate() exists, the body will be decompressed.
Parameters
-
string$body Gzip encoded body.
Returns
stringThrows
RuntimeExceptionWhen attempting to decode gzip content without gzinflate.
_getJson() ¶ protected
_getJson(): null|arrayGet the response body as JSON decoded data.
Returns
null|array_getXml() ¶ protected
_getXml(): null|SimpleXMLElementGet the response body as XML decoded data.
Returns
null|SimpleXMLElement_normalizeHeader() ¶ protected
_normalizeHeader(string $name): stringNormalize header names to Camel-Case form.
Parameters
-
string$name The header name to normalize.
Returns
