URL Parser and Builder

The Url, UrlImmutable, and UrlScript classes make it easy to manage, parse, and manipulate URLs.

Installation:

composer require nette/http

Url

The Nette\Http\Url class makes it easy to work with the URL and its individual components, which are outlined in this diagram:

scheme  user  password  host   port    path        query  fragment
  |      |      |        |      |       |            |       |
/--\   /--\ /------\ /-------\ /--\/----------\ /--------\ /----\
http://john:xyz%2A12@nette.org:8080/en/download?name=param#footer
\______\__________________________/
    |               |
 hostUrl        authority

URL generation is intuitive:

use Nette\Http\Url;

$url = new Url;
$url->setScheme('https')
	->setHost('localhost')
	->setPath('/edit')
	->setQueryParameter('foo', 'bar');

echo $url; // https://localhost/edit?foo=bar

You can also parse the URL and then manipulate it:

$url = new Url(
	'http://john:xyz%2A12@nette.org:8080/en/download?name=param#footer'
);

The following methods are available to get or change individual URL components:

Setter	Getter	Returned value
setScheme(string $scheme)	getScheme(): string	'http'
setUser(string $user)	getUser(): string	'john'
setPassword(string $password)	getPassword(): string	'xyz*12'
setHost(string $host)	getHost(): string	'nette.org'
setPort(int $port)	getPort(): ?int	8080
setPath(string $path)	getPath(): string	'/en/download'
setQuery(string|array $query)	getQuery(): string	'name=param'
setFragment(string $fragment)	getFragment(): string	'footer'
	getAuthority(): string	'nette.org:8080'
	getHostUrl(): string	'http://nette.org:8080'
	getAbsoluteUrl(): string	full URL

We can also access query parameters using:

Setter	Getter
setQuery(string|array $query)	getQueryParameters(): array
setQueryParameter(string $name, $val)	getQueryParameter(string $name)

Method getDomain(int $level = 2) returns the right or left part of the host. This is how it works if the host is www.nette.org:

getDomain(1)	'org'
getDomain(2)	'nette.org'
getDomain(3)	'www.nette.org'
getDomain(0)	'www.nette.org'
getDomain(-1)	'www.nette'
getDomain(-2)	'www'
getDomain(-3)	''

The Url class implements the JsonSerializable interface and has a __toString() method so that the object can be printed or used in data passed to json_encode().

echo $url;
echo json_encode([$url]);

Method isEqual(string|Url $anotherUrl): bool tests whether the two URLs are identical.

echo $url->isEqual('https://nette.org');

UrlImmutable

The class Nette\Http\UrlImmutable is an immutable alternative to class Url (just as in PHP DateTimeImmutable is immutable alternative to DateTime). Instead of setters, it has so-called withers, which do not change the object, but return new instances with a modified value:

use Nette\Http\UrlImmutable;

$url = new UrlImmutable(
	'http://john:xyz%2A12@nette.org:8080/en/download?name=param#footer'
);

$newUrl = $url
	->withUser('')
	->withPassword('')
	->withPath('/cs/');

echo $newUrl; // http://nette.org:8080/cs/?name=param#footer

The following methods are available to get or change individual URL components:

Wither	Getter	Returned value
withScheme(string $scheme)	getScheme(): string	'http'
withUser(string $user)	getUser(): string	'john'
withPassword(string $password)	getPassword(): string	'xyz*12'
withHost(string $host)	getHost(): string	'nette.org'
withPort(int $port)	getPort(): ?int	8080
withPath(string $path)	getPath(): string	'/en/download'
withQuery(string|array $query)	getQuery(): string	'name=param'
withFragment(string $fragment)	getFragment(): string	'footer'
	getAuthority(): string	'nette.org:8080'
	getHostUrl(): string	'http://nette.org:8080'
	getAbsoluteUrl(): string	full URL

We can also access query parameters using:

Wither	Getter
withQuery(string|array $query)	getQueryParameters(): array
	getQueryParameter(string $name)

The getDomain(int $level = 2) method works the same as the method in Url. Method withoutUserInfo() removes user and password.

The UrlImmutable class implements the JsonSerializable interface and has a __toString() method so that the object can be printed or used in data passed to json_encode().

echo $url;
echo json_encode([$url]);

Method isEqual(string|Url $anotherUrl): bool tests whether the two URLs are identical.

UrlScript

The Nette\Http\UrlScript class is a descendant of UrlImmutable and additionally distinguishes these logical parts of the URL:

     baseUrl    basePath  relativePath  relativeUrl
        |          |        |               |
/---------------/-----\/--------\---------------------------\
http://nette.org/admin/script.php/pathinfo/?name=param#footer
                \_______________/\________/
                       |              |
                  scriptPath       pathInfo

The following methods are available to get these parts:

Getter	Returned value
getScriptPath(): string	'/admin/script.php'
getBasePath(): string	'/admin/'
getBaseUrl(): string	'http://nette.org/admin/'
getRelativePath(): string	'script.php'
getRelativeUrl(): string	'script.php/pathinfo/?name=param#footer'
getPathInfo(): string	'/pathinfo/'

We do not create objects UrlScript directly, but the method Nette\Http\Request::getUrl() returns it.
