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 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');

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 operate with individual 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.
