__construct()


    public
                    __construct([string $uri = '' ]) : mixed

Parameters

$uri : string = '': The full URI including query string and fragment

__toString()

Return the string representation as a URI reference.


    public
                    __toString() : string

Depending on which components of the URI are present, the resulting string is either a full URI or relative reference according to RFC 3986, Section 4.1. The method concatenates the various components of the URI, using the appropriate delimiters:

If a scheme is present, it MUST be suffixed by ":".
If an authority is present, it MUST be prefixed by "//".
The path can be concatenated without delimiters. But there are two cases where the path has to be adjusted to make the URI reference valid as PHP does not allow to throw an exception in __toString():
- If the path is rootless and an authority is present, the path MUST be prefixed by "/".
- If the path is starting with more than one "/" and no authority is present, the starting slashes MUST be reduced to one.
If a query is present, it MUST be prefixed by "?".
If a fragment is present, it MUST be prefixed by "#".

Return values

string

getAuthority()

Retrieve the authority component of the URI.


    public
                    getAuthority() : string

If no authority information is present, this method MUST return an empty string.

The authority syntax of the URI is:

[user-info@]host[:port]

If the port component is not set or is the standard port for the current scheme, it SHOULD NOT be included.

Return values

string —

The URI authority, in "[user-info@]host[:port]" format.

getFragment()

Retrieve the fragment component of the URI.


    public
                    getFragment() : string

If no fragment is present, this method MUST return an empty string.

The leading "#" character is not part of the fragment and MUST NOT be added.

The value returned MUST be percent-encoded, but MUST NOT double-encode any characters. To determine what characters to encode, please refer to RFC 3986, Sections 2 and 3.5.

Return values

string —

The URI fragment.

getHost()

Retrieve the host component of the URI.


    public
                    getHost() : string

If no host is present, this method MUST return an empty string.

The value returned MUST be normalized to lowercase, per RFC 3986 Section 3.2.2.

Return values

string —

The URI host.

getPath()

Retrieve the path component of the URI.


    public
                    getPath() : string

The path can either be empty or absolute (starting with a slash) or rootless (not starting with a slash). Implementations MUST support all three syntaxes.

Normally, the empty path "" and absolute path "/" are considered equal as defined in RFC 7230 Section 2.7.3. But this method MUST NOT automatically do this normalization because in contexts with a trimmed base path, e.g. the front controller, this difference becomes significant. It's the task of the user to handle both "" and "/".

The value returned MUST be percent-encoded, but MUST NOT double-encode any characters. To determine what characters to encode, please refer to RFC 3986, Sections 2 and 3.3.

As an example, if the value should include a slash ("/") not intended as delimiter between path segments, that value MUST be passed in encoded form (e.g., "%2F") to the instance.

Return values

string —

The URI path.

getPort()

Retrieve the port component of the URI.


    public
                    getPort() : int|null

If a port is present, and it is non-standard for the current scheme, this method MUST return it as an integer. If the port is the standard port used with the current scheme, this method SHOULD return null.

If no port is present, and no scheme is present, this method MUST return a null value.

If no port is present, but a scheme is present, this method MAY return the standard port for that scheme, but SHOULD return null.

Return values

int|null —

The URI port.

getQuery()

Retrieve the query string of the URI.


    public
                    getQuery() : string

If no query string is present, this method MUST return an empty string.

The leading "?" character is not part of the query and MUST NOT be added.

The value returned MUST be percent-encoded, but MUST NOT double-encode any characters. To determine what characters to encode, please refer to RFC 3986, Sections 2 and 3.4.

As an example, if a value in a key/value pair of the query string should include an ampersand ("&") not intended as a delimiter between values, that value MUST be passed in encoded form (e.g., "%26") to the instance.

Return values

string —

The URI query string.

getScheme()

Retrieve the scheme component of the URI.


    public
                    getScheme() : string

If no scheme is present, this method MUST return an empty string.

The value returned MUST be normalized to lowercase, per RFC 3986 Section 3.1.

The trailing ":" character is not part of the scheme and MUST NOT be added.

Return values

string —

The URI scheme.

getUserInfo()

Retrieve the user information component of the URI.


    public
                    getUserInfo() : string

If no user information is present, this method MUST return an empty string.

If a user is present in the URI, this will return that value; additionally, if the password is also present, it will be appended to the user value, with a colon (":") separating the values.

The trailing "@" character is not part of the user information and MUST NOT be added.

Return values

string —

The URI user information, in "username[:password]" format.

withFragment()

Return an instance with the specified URI fragment.


    public
                    withFragment(string $fragment) : static

This method MUST retain the state of the current instance, and return an instance that contains the specified URI fragment.

Users can provide both encoded and decoded fragment characters. Implementations ensure the correct encoding as outlined in getFragment().

An empty fragment value is equivalent to removing the fragment.

Parameters

$fragment : string: The fragment to use with the new instance.

Return values

static —

A new instance with the specified fragment.

withHost()

Return an instance with the specified host.


    public
                    withHost(string $host) : static

This method MUST retain the state of the current instance, and return an instance that contains the specified host.

An empty host value is equivalent to removing the host.

Parameters

$host : string: The hostname to use with the new instance.

Return values

static —

A new instance with the specified host.

withPath()

Return an instance with the specified path.


    public
                    withPath(string $path) : static

This method MUST retain the state of the current instance, and return an instance that contains the specified path.

The path can either be empty or absolute (starting with a slash) or rootless (not starting with a slash). Implementations MUST support all three syntaxes.

If the path is intended to be domain-relative rather than path relative then it must begin with a slash ("/"). Paths not starting with a slash ("/") are assumed to be relative to some base path known to the application or consumer.

Users can provide both encoded and decoded path characters. Implementations ensure the correct encoding as outlined in getPath().

Parameters

$path : string: The path to use with the new instance.

Return values

static —

A new instance with the specified path.

withPort()

Return an instance with the specified port.


    public
                    withPort(int|null $port) : static

This method MUST retain the state of the current instance, and return an instance that contains the specified port.

Implementations MUST raise an exception for ports outside the established TCP and UDP port ranges.

A null value provided for the port is equivalent to removing the port information.

Parameters

$port : int|null: The port to use with the new instance; a null value removes the port information.

Return values

static —

A new instance with the specified port.

withQuery()

Return an instance with the specified query string.


    public
                    withQuery(string $query) : static

This method MUST retain the state of the current instance, and return an instance that contains the specified query string.

Users can provide both encoded and decoded query characters. Implementations ensure the correct encoding as outlined in getQuery().

An empty query string value is equivalent to removing the query string.

Parameters

$query : string: The query string to use with the new instance.

Return values

static —

A new instance with the specified query string.

withScheme()

Return an instance with the specified scheme.


    public
                    withScheme(string $scheme) : static

This method MUST retain the state of the current instance, and return an instance that contains the specified scheme.

Implementations MUST support the schemes "http" and "https" case insensitively, and MAY accommodate other schemes if required.

An empty scheme is equivalent to removing the scheme.

Parameters

$scheme : string: The scheme to use with the new instance.

Return values

static —

A new instance with the specified scheme.

withUserInfo()

Return an instance with the specified user information.


    public
                    withUserInfo(string $user[, string|null $password = null ]) : static

This method MUST retain the state of the current instance, and return an instance that contains the specified user information.

Password is optional, but the user information MUST include the user; an empty string for the user is equivalent to removing user information.

Parameters

$user : string: The username to use for authority.
$password : string|null = null: The password associated with $user.

Return values

static —

A new instance with the specified user information.
