URL Parser and Builder

The Url 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 operate with individual 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.

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

UrlScript

The Nette\Http\UrlScript class is a descendant of Url 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.
