◆ __set()

Slim\Http\Message::__set (   $name,
  $value 
)

Disable magic setter to ensure immutability.

Definition at line 64 of file Message.php.

65  {
66  // Do nothing
67  }

◆ getBody()

Slim\Http\Message::getBody ( )

Gets the body of the message.

Returns
StreamInterface Returns the body as a stream.

Implements Psr\Http\Message\MessageInterface.

+ Here is the caller graph for this function:

◆ getHeader()

Slim\Http\Message::getHeader (   $name)

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

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
string$nameCase-insensitive header field name.
Returns
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.

175  {
176  return $this->headers->get($name, []);
177  }
+ Here is the caller graph for this function:

◆ getHeaderLine()

Slim\Http\Message::getHeaderLine (   $name)

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

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
string$nameCase-insensitive header field name.
Returns
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.

Implements Psr\Http\Message\MessageInterface.

199  {
200  return implode(',', $this->headers->get($name, []));
201  }
+ Here is the caller graph for this function:

◆ getHeaders()

Slim\Http\Message::getHeaders ( )

Retrieves all message header values.

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.

Returns
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 for that header.

Implements Psr\Http\Message\MessageInterface.

+ Here is the caller graph for this function:

◆ getProtocolVersion()

Slim\Http\Message::getProtocolVersion ( )

Retrieves the HTTP protocol version as a string.

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

Returns
string HTTP protocol version.

+ Here is the caller graph for this function:

◆ hasHeader()

Slim\Http\Message::hasHeader (   $name)

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

Parameters
string$nameCase-insensitive header field name.
Returns
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.

+ Here is the caller graph for this function:

◆ withAddedHeader()

Slim\Http\Message::withAddedHeader (   $name,
  $value 
)

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

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
string$nameCase-insensitive header field name to add.
string|string[]$value Header value(s).
Returns
static

248  }

◆ withBody()

Slim\Http\Message::withBody ( StreamInterface  $body)

Return an instance with the specified message body.

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
StreamInterface$bodyBody.

+ Here is the caller graph for this function:

◆ withHeader()

Slim\Http\Message::withHeader (   $name,
  $value 
)

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

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
string$nameCase-insensitive header field name.
string|string[]$value Header value(s).
Returns
static

◆ withoutHeader()

Slim\Http\Message::withoutHeader (   $name)

Return an instance without the specified header.

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
string$nameCase-insensitive header field name to remove.
Returns

◆ withProtocolVersion()

Slim\Http\Message::withProtocolVersion (   $version)

Return an instance with the specified HTTP protocol version.

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.
