Method Details

getBody() public method

Gets the body of the message.
public getBody ( ) : Psr\Http\Message\StreamInterface
return Psr\Http\Message\StreamInterface Returns the body as a stream.

getHeader() public method

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.
public getHeader ( string $header ) : string[]
$header string Case-insensitive header field name.
return 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() public method

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.
public getHeaderLine ( string $name ) : string
$name string Case-insensitive header field name.
return 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() public method

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); } }
public getHeaders ( ) : array
return array 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.

getProtocolVersion() public method

The string MUST contain only the HTTP version number (e.g., "1.1", "1.0").
public getProtocolVersion ( ) : string
return string HTTP protocol version.

hasHeader() public method

Checks if a header exists by the given case-insensitive name.
public hasHeader ( string $header ) : boolean
$header string Case-insensitive header name.
return boolean 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() public method

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.
public withAddedHeader ( string $header, string | string[] $value ) : static
$header string Case-insensitive header field name to add.
$value string | string[] Header value(s).
return static

withBody() public method

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.
public withBody ( Psr\Http\Message\StreamInterface $body ) : static
$body Psr\Http\Message\StreamInterface Body.
return static

withHeader() public method

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.
public withHeader ( string $header, string | string[] $value ) : static
$header string Case-insensitive header field name.
$value string | string[] Header value(s).
return static

withProtocolVersion() public method

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.
public withProtocolVersion ( string $version ) : static
$version string HTTP protocol version
return static

withoutHeader() public method

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.
public withoutHeader ( string $header ) : static
$header string Case-insensitive header field name to remove.
return static
