Properties

$header

private array<string, array<string|int, string>> $header = []

Methods

__construct()

public __construct([array<string, mixed> $Config = [] ]) : mixed
Parameters
$Config : array<string, mixed> = []

The configuration.

getBody()

Gets the body of the message.

public getBody() : StreamInterface
Return values
StreamInterface —

Returns the body as a stream.

getContentType()

Retrieve content type.

public getContentType() : string
Return values
string

getHeader()

Retrieves a message header value by the given case-insensitive name.

public getHeader(string $name) : array<string|int, string>

This method returns an array of all the header values of the given case-insensitive header name.

If the header does not appear in the message, this method MUST return an empty array.

Parameters
$name : string

Case-insensitive header field name.

Return values
array<string|int, string> —

An array of string values as provided for the given header. If the header does not appear in the message, this method MUST return an empty array.

getHeaderLine()

Retrieves a comma-separated string of the values for a single header.

public getHeaderLine(string $name) : string

This method returns all of the header values of the given case-insensitive header name as a string concatenated together using a comma.

NOTE: Not all header values may be appropriately represented using comma concatenation. For such headers, use getHeader() instead and supply your own delimiter when concatenating.

If the header does not appear in the message, this method MUST return an empty string.

Parameters
$name : string

Case-insensitive header field name.

Return values
string —

A string of values as provided for the given header concatenated together using a comma. If the header does not appear in the message, this method MUST return an empty string.

getHeaders()

Retrieves all message header values.

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

The keys represent the header name as it will be sent over the wire, and each value is an array of strings associated with the header.

// Represent the headers as a string
foreach ($message->getHeaders() as $name => $values) {
    echo $name . ": " . implode(", ", $values);
}

// Emit headers iteratively:
foreach ($message->getHeaders() as $name => $values) {
    foreach ($values as $value) {
        header(sprintf('%s: %s', $name, $value), false);
    }
}

While header names are not case-sensitive, getHeaders() will preserve the exact case in which headers were originally specified.

Return values
array<string|int, array<string|int, string>> —

Returns an associative array of the message's headers. Each key MUST be a header name, and each value MUST be an array of strings for that header.

getProtocolVersion()

Retrieves the HTTP protocol version as a string.

public getProtocolVersion() : string

The string MUST contain only the HTTP version number (e.g., "1.1", "1.0").

Return values
string —

HTTP protocol version.

getReasonPhrase()

Gets the response reason phrase associated with the status code.

public getReasonPhrase() : string

Because a reason phrase is not a required element in a response status line, the reason phrase value MAY be null. Implementations MAY choose to return the default RFC 7231 recommended reason phrase (or those listed in the IANA HTTP Status Code Registry) for the response's status code.

http://tools.ietf.org/html/rfc7231#section-6
link
http://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml
Return values
string —

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

getStatusCode()

Gets the response status code.

public getStatusCode() : int

The status code is a 3-digit integer result code of the server's attempt to understand and satisfy the request.

Return values
int —

Status code.

hasHeader()

Checks if a header exists by the given case-insensitive name.

public hasHeader(string $name) : bool
Parameters
$name : string

Case-insensitive header field name.

Return values
bool —

Returns true if any header names match the given header name using a case-insensitive string comparison. Returns false if no matching header name is found in the message.

withAddedHeader()

Return an instance with the specified header appended with the given value.

public withAddedHeader(string $name, string|array<string|int, string> $value) : static

Existing values for the specified header will be maintained. The new value(s) will be appended to the existing list. If the header did not exist previously, it will be added.

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 header and/or value.

Parameters
$name : string

Case-insensitive header field name to add.

$value : string|array<string|int, string>

Header value(s).

Tags
throws
InvalidArgumentException

for invalid header names or values.

Return values
static

withBody()

Return an instance with the specified message body.

public withBody(StreamInterface $body) : static

The body MUST be a StreamInterface object.

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

Parameters
$body : StreamInterface

Body.

Tags
throws
InvalidArgumentException

When the body is not valid.

Return values
static

withContentType()

Return an instance with the provided value replacing the specified header content type.

public withContentType(string $Value) : static
Parameters
$Value : string

The content type.

Return values
static

withHeader()

Return an instance with the provided value replacing the specified header.

public withHeader(string $name, string|array<string|int, string> $value) : static

While header names are case-insensitive, the casing of the header will be preserved by this function, and returned from getHeaders().

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 and/or updated header and value.

Parameters
$name : string

Case-insensitive header field name.

$value : string|array<string|int, string>

Header value(s).

Tags
throws
InvalidArgumentException

for invalid header names or values.

Return values
static

withoutHeader()

Return an instance without the specified header.

public withoutHeader(string $name) : static

Header resolution MUST be done without case-sensitivity.

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 named header.

Parameters
$name : string

Case-insensitive header field name to remove.

Return values
static

withProtocolVersion()

Return an instance with the specified HTTP protocol version.

public withProtocolVersion(string $version) : static

The version string MUST contain only the HTTP version number (e.g., "1.1", "1.0").

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 protocol version.

Parameters
$version : string

HTTP protocol version

Return values
static

withStatus()

Return an instance with the specified status code and, optionally, reason phrase.

public withStatus(int $code[, string $reasonPhrase = '' ]) : static

If no reason phrase is specified, implementations MAY choose to default to the RFC 7231 or IANA recommended reason phrase for the response's status code.

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 status and reason phrase.

Parameters
$code : int

The 3-digit integer result code to set.

$reasonPhrase : string = ''

The reason phrase to use with the provided status code; if none is provided, implementations MAY use the defaults as suggested in the HTTP specification.
