ServerRequest extends Request
in package
implements ServerRequestInterface

Server-side HTTP request

Extends the Request definition to add methods for accessing incoming data, specifically server parameters, cookies, matched path parameters, query string arguments, body parameters, and upload file information.

"Attributes" are discovered via decomposing the request (and usually specifically the URI path), and typically will be injected by the application.

Requests are considered immutable; all methods that might change state are implemented such that they retain the internal state of the current message and return a new instance that contains the changed state.

__construct()

public __construct(string $method, string|UriInterface $uri[, array<string|int, string|array<string|int, string>> $headers = [] ][, string|resource|StreamInterface|null $body = null ][, string $version = '1.1' ][, array<string|int, mixed> $serverParams = [] ]) : mixed
Parameters
$method : string

HTTP method

$uri : string|UriInterface

URI

$headers : array<string|int, string|array<string|int, string>> = []

Request headers

$body : string|resource|StreamInterface|null = null

Request body

$version : string = '1.1'

Protocol version

$serverParams : array<string|int, mixed> = []

Typically the $_SERVER superglobal

getAttribute()

Retrieve a single derived request attribute.

public getAttribute(mixed $attribute[, mixed $default = null ]) : mixed
Parameters
$attribute : mixed
$default : mixed = null

Default value to return if the attribute does not exist.

getAttributes()

Retrieve attributes derived from the request.

public getAttributes() : array<string|int, mixed>

The request "attributes" may be used to allow injection of any parameters derived from the request: e.g., the results of path match operations; the results of decrypting cookies; the results of deserializing non-form-encoded message bodies; etc. Attributes will be application and request specific, and CAN be mutable.

Return values
array<string|int, mixed> —

Attributes derived from the request.

getCookieParams()

Retrieve cookies.

public getCookieParams() : array<string|int, mixed>

Retrieves cookies sent by the client to the server.

The data MUST be compatible with the structure of the $_COOKIE superglobal.

Return values
array<string|int, mixed>

getHeader()

public getHeader(mixed $header) : array<string|int, mixed>
Parameters
$header : mixed
Return values
array<string|int, mixed>

getHeaderLine()

public getHeaderLine(mixed $header) : string
Parameters
$header : mixed
Return values
string

getHeaders()

public getHeaders() : array<string|int, mixed>

Return values
string

getQueryParams()

Retrieve query string arguments.

public getQueryParams() : array<string|int, mixed>

Retrieves the deserialized query string arguments, if any.

Note: the query params might not be in sync with the URI or server params. If you need to ensure you are only getting the original values, you may need to parse the query string from getUri()->getQuery() or from the QUERY_STRING server param.

Return values
array<string|int, mixed>

getRequestTarget()

Retrieves the message's request target.

public getRequestTarget() : string

Retrieves the message's request-target either as it will appear (for clients), as it appeared at request (for servers), or as it was specified for the instance (see withRequestTarget()).

In most cases, this will be the origin-form of the composed URI, unless a value was provided to the concrete implementation (see withRequestTarget() below).

If no URI is available, and no request-target has been specifically provided, this method MUST return the string "/".

Return values
string

getServerParams()

Retrieve server parameters.

public getServerParams() : array<string|int, mixed>

Retrieves data related to the incoming request environment, typically derived from PHP's $_SERVER superglobal. The data IS NOT REQUIRED to originate from $_SERVER.

Return values
array<string|int, mixed>

getUploadedFiles()

Retrieve normalized file upload data.

public getUploadedFiles() : array<string|int, mixed>

This method returns upload metadata in a normalized tree, with each leaf an instance of Psr\Http\Message\UploadedFileInterface.

These values MAY be prepared from $_FILES or the message body during instantiation, or MAY be injected via withUploadedFiles().

Return values
array<string|int, mixed> —

An array tree of UploadedFileInterface instances; an empty array MUST be returned if no data is present.

getUri()

Retrieves the URI instance.

public getUri() : UriInterface

This method MUST return a UriInterface instance.

Return values
UriInterface —

Returns a UriInterface instance representing the URI of the request.

An array which respect $_FILES structure

Tags
throws
InvalidArgumentException

for unrecognized values

Return values
array<string|int, mixed>

withAddedHeader()

public withAddedHeader(mixed $header, mixed $value) : MessageInterface
Parameters
$header : mixed
$value : mixed
Return values
MessageInterface

withAttribute()

Return an instance with the specified derived request attribute.

public withAttribute(mixed $attribute, mixed $value) : static

This method allows setting a single derived request attribute as described in getAttributes().

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated attribute.

Parameters
$attribute : mixed
$value : mixed

The value of the attribute.

Return values
static

withCookieParams()

Return an instance with the specified cookies.

public withCookieParams(array<string|int, mixed> $cookies) : static

The data IS NOT REQUIRED to come from the $_COOKIE superglobal, but MUST be compatible with the structure of $_COOKIE. Typically, this data will be injected at instantiation.

This method MUST NOT update the related Cookie header of the request instance, nor related values in the server params.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated cookie values.

Parameters
$cookies : array<string|int, mixed>

Array of key/value pairs representing cookies.

Return values
static

withMethod()

Return an instance with the provided HTTP method.

public withMethod(mixed $method) : static

While HTTP method names are typically all uppercase characters, HTTP method names are case-sensitive and thus implementations SHOULD NOT modify the given string.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the changed request method.

Parameters
$method : mixed

Case-sensitive method.

Return values
static

withoutAttribute()

Return an instance that removes the specified derived request attribute.

public withoutAttribute(mixed $attribute) : static

This method allows removing a single derived request attribute as described in getAttributes().

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that removes the attribute.

Parameters
$attribute : mixed
Return values
static

withParsedBody()

Return an instance with the specified body parameters.

public withParsedBody(mixed $data) : static

These MAY be injected during instantiation.

If the request Content-Type is either application/x-www-form-urlencoded or multipart/form-data, and the request method is POST, use this method ONLY to inject the contents of $_POST.

The data IS NOT REQUIRED to come from $_POST, but MUST be the results of deserializing the request body content. Deserialization/parsing returns structured data, and, as such, this method ONLY accepts arrays or objects, or a null value if nothing was available to parse.

As an example, if content negotiation determines that the request data is a JSON payload, this method could be used to create a request instance with the deserialized parameters.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated body parameters.

Parameters
$data : mixed

The deserialized body data. This will typically be in an array or object.

Return values
static

withQueryParams()

Return an instance with the specified query string arguments.

public withQueryParams(array<string|int, mixed> $query) : static

These values SHOULD remain immutable over the course of the incoming request. They MAY be injected during instantiation, such as from PHP's $_GET superglobal, or MAY be derived from some other value such as the URI. In cases where the arguments are parsed from the URI, the data MUST be compatible with what PHP's parse_str() would return for purposes of how duplicate query parameters are handled, and how nested sets are handled.

Setting query string arguments MUST NOT change the URI stored by the request, nor the values in the server params.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated query string arguments.

Parameters
$query : array<string|int, mixed>

Array of query string arguments, typically from $_GET.

Return values
static

withRequestTarget()

Return an instance with the specific request-target.

public withRequestTarget(mixed $requestTarget) : static

If the request needs a non-origin-form request-target — e.g., for specifying an absolute-form, authority-form, or asterisk-form — this method may be used to create an instance with the specified request-target, verbatim.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the changed request target.

Parameters
$requestTarget : mixed
Return values
static

withUploadedFiles()

Create a new instance with the specified uploaded files.

public withUploadedFiles(array<string|int, mixed> $uploadedFiles) : static

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated body parameters.

Parameters
$uploadedFiles : array<string|int, mixed>

An array tree of UploadedFileInterface instances.

Return values
static

withUri()

Returns an instance with the provided URI.

public withUri(UriInterface $uri[, mixed $preserveHost = false ]) : static

This method MUST update the Host header of the returned request by default if the URI contains a host component. If the URI does not contain a host component, any pre-existing Host header MUST be carried over to the returned request.

You can opt-in to preserving the original state of the Host header by setting $preserveHost to true. When $preserveHost is set to true, this method interacts with the Host header in the following ways:

  • If the Host header is missing or empty, and the new URI contains a host component, this method MUST update the Host header in the returned request.
  • If the Host header is missing or empty, and the new URI does not contain a host component, this method MUST NOT update the Host header in the returned request.
  • If a Host header is present and non-empty, this method MUST NOT update the Host header in the returned request.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the new UriInterface instance.

Parameters
$uri : UriInterface

New request URI to use.

$preserveHost : mixed = false

Preserve the original state of the Host header.

Return values
static
