◆ getHeader()

Sabre\HTTP\getHeader ( $name )

Returns a specific HTTP header, based on it's name.

The name must be treated as case-insensitive. If the header does not exist, this method must return null.

If a header appeared more than once in a HTTP request, this method will concatenate all the values with a comma.

Note that this not make sense for all headers. Some, such as Set-Cookie cannot be logically combined with a comma. In those cases you should use getHeaderAsArray().

Parameters

string $name

Returns: string|null

Definition at line 121 of file MessageDecoratorTrait.php.

                              {

    }

References $name.

◆ getHeaderAsArray()

Sabre\HTTP\getHeaderAsArray ( $name )

Returns a HTTP header as an array.

For every time the HTTP header appeared in the request or response, an item will appear in the array.

If the header did not exists, this method will return an empty array.

Parameters

string $name

Returns: string[]

Definition at line 138 of file MessageDecoratorTrait.php.

                                     {

Here is the caller graph for this function:

◆ getHeaderValues()

Sabre\HTTP\getHeaderValues	(	$values,
		$values2 = `null`
	)

This method splits up headers into all their individual values.

A HTTP header may have more than one header, such as this: Cache-Control: private, no-store

Header values are always split with a comma.

You can pass either a string, or an array. The resulting value is always an array with each spliced value.

If the second headers argument is set, this value will simply be merged in. This makes it quicker to merge an old list of values with a new set.

Parameters

string \| string[]	$values
string \| string[]	$values2

Returns: string[]

Definition at line 301 of file functions.php.

                                                   {

References $name.

◆ negotiateContentType()

Sabre\HTTP\negotiateContentType	(		$acceptHeaderValue,
		array	$availableOptions
	)

This function can be used to aid with content negotiation.

It takes 2 arguments, the $acceptHeaderValue, which usually comes from an Accept header, and $availableOptions, which contains an array of items that the server can support.

The result of this function will be the 'best possible option'. If no best possible option could be found, null is returned.

When it's null you can according to the spec either return a default, or you can choose to emit 406 Not Acceptable.

The method also accepts sending 'null' for the $acceptHeaderValue, implying that no accept header was sent.

Parameters

string \| null	$acceptHeaderValue
array	$availableOptions

Returns: string|null

◆ parsePrefer()

Sabre\HTTP\parsePrefer ( $input )

Parses the Prefer header, as defined in RFC7240.

Input can be given as a single header value (string) or multiple headers (array of string).

This method will return a key->value array with the various Prefer parameters.

Prefer: return=minimal will result in:

[ 'return' => 'minimal' ]

Prefer: foo, wait=10 will result in:

[ 'foo' => true, 'wait' => '10']

This method also supports the formats from older drafts of RFC7240, and it will automatically map them to the new values, as the older values are still pretty common.

Parameters are currently discarded. There's no known prefer value that uses them.

Parameters

string | string[] $input

Returns: array

Variable Documentation

◆ MessageDecoratorTrait

trait Sabre::HTTP\MessageDecoratorTrait

Initial value:

{
 
    protected $inner

This trait contains a bunch of methods, shared by both the RequestDecorator and the ResponseDecorator.

Didn't seem needed to create a full class for this, so we're just implementing it as a trait.
