README

Object-oriented wrapper/manipulator for parse_url with the following features:

• Read URI parts as objects (Scheme, Host, Path, Query), each with their own set of features.
• Manipulate URI parts or build URI's using a fluent builder API.
• Sign and verify URI's and make them temporary and/or single-use.
• Mailto object to help with reading/manipulating mailto: URIs.
• URI Template (RFC 6570) support.
• PSR-13 Link implementation/bridge.
• Twig Extension.

This library is meant as a wrapper for PHP's parse_url function only and does not conform to any URI-related PSR or RFC. If you need this, league/uri would be a better choice.

Installation

composer require zenstruck/uri

Parsing/Reading URIs

use Zenstruck\Uri\ParsedUri;

// wrap a uri (this URI will be used for many of the samples below)
$uri = ParsedUri::wrap('https://username:password@example.com/some/dir/file.html?q=abc&flag=1#test');

// can wrap an instance of \Symfony\Component\HttpFoundation\Request
$uri = ParsedUri::wrap($request);

// URIs are stringable
$uri->toString();
(string) $uri;

// check if absolute
$uri->isAbsolute(); // true
ParsedUri::wrap('/some/path/only')->isAbsolute(); // false

// SCHEME
$uri->scheme()->toString(); // "https"
$uri->scheme()->equals('https'); // true
$uri->scheme()->in(['https', 'http']); // true

// scheme segments - ie some kind of dsn (delimiter defaults to "+")
ParsedUri::wrap('postmark+smtp://id')->scheme()->segments(); // ["postmark", "smtp"]
ParsedUri::wrap('postmark+smtp://id')->scheme()->segment(0); // "postmark"
ParsedUri::wrap('postmark+smtp://id')->scheme()->segment(1); // "smtp"

// HOST
$uri->host()->toString(); // example.com
$uri->host()->segments(); // ["example", "com"]
$uri->host()->segment(0); // "example"
$uri->host()->tld(); // "com"

// USER/PASS
$uri->username(); // "username"

$uri->path()->dirname(); // "/some/dir"
$uri->path()->filename(); // "file"
$uri->path()->basename(); // "file.html"
$uri->path()->extension(); // "html"

// path helper methods
ParsedUri::wrap('/some/dir/')->path()->rtrim(); // "/some/dir"
ParsedUri::wrap('/some/dir')->path()->isAbsolute(); // true
ParsedUri::wrap('some/dir')->path()->isAbsolute(); // false
ParsedUri::wrap('/some/dir/..')->path()->absolute(); // "/some"
ParsedUri::wrap('/..')->path()->absolute(); // (throws \RuntimeException - path outside of root)

$uri->fragment(); // "test"

ParsedUri::wrap('http://example.com')->fragment(); // (null)
ParsedUri::wrap('http://example.com#frag%20ment')->fragment(); // "frag ment" (urldecoded)

Manipulating URIs

Note: Zenstruck\Uri\ParsedUri is an immutable object so any manipulations results in a new instance.

use Zenstruck\Uri\ParsedUri;

// URI used for the following examples
$uri = ParsedUri::wrap('https://user:pass@example.com/path?q=abc&flag=1#test');

// SCHEME
$uri->withScheme('http')->toString(); // "http://user:pass@example.com/path?q=abc&flag=1#test"
$uri->withoutScheme()->toString(); // "//user:pass@example.com/path?q=abc&flag=1#test"

// HOST
$uri->withHost('localhost')->toString(); // "https://user:pass@localhost/path?q=abc&flag=1#test"
$uri->withoutHost()->toString(); // "https:/path?q=abc&flag=1#test" (removes username/password/port as well)

// USER
$uri->withUsername('foo@bar.com')->toString(); // "https://foo%40bar.com:pass@example.com/path?q=abc&flag=1#test" (urlencoded)
$uri->withoutUsername()->toString(); // "https://example.com/path?q=abc&flag=1#test" (removes password as well)

// PASSWORD
$uri->withPassword('pass#word')->toString(); // "https://user:pass%23word@example.com/path?q=abc&flag=1#test" (urlencoded)
$uri->withoutPassword()->toString(); // "https://user@example.com/path?q=abc&flag=1#test"

// PORT
$uri->withPort(555)->toString(); // "https://user:pass@example.com:555/path?q=abc&flag=1#test"
ParsedUri::new('http://example.com:22')->withoutPort()->toString(); // "http://example.com"

// PATH
$uri->withPath('/replace')->toString(); // "https://user:pass@example.com/replace?q=abc&flag=1#test"
$uri->withoutPath()->toString(); // "https://user:pass@example.com?q=abc&flag=1#test"
$uri->prependPath('/prefix')->toString(); // "https://user:pass@example.com/prefix/path?q=abc&flag=1#test"
$uri->appendPath('/suffix')->toString(); // "https://user:pass@example.com/path/suffix?q=abc&flag=1#test"

// QUERY
$uri->withQuery(['foo' => 'bar'])->toString(); // "https://user:pass@example.com/path?foo=bar#test"
$uri->withQueryParam('foo', 'bar')->toString(); // "https://user:pass@example.com/path?q=abc&flag=1&foo=bar#test"
$uri->withoutQuery()->toString(); // "https://user:pass@example.com/path#test"
$uri->withoutQueryParams('q', 'missing')->toString(); // "https://user:pass@example.com/path?flag=1#test"
$uri->withOnlyQueryParams('q', 'missing')->toString(); // "https://user:pass@example.com/path?q=abc#test"

// FRAGMENT
$uri->withFragment('frag ment')->toString(); // "https://user:pass@example.com/path?q=abc&flag=1#frag%20ment" (urlencoded)
$uri->withoutFragment()->toString(); // "https://user:pass@example.com/path?q=abc&flag=1"

// URI Builder
ParsedUri::new()
    ->withHost('example.com')
    ->withScheme('https')
    ->withPath('/path')
    // ...
    ->toString() // "https://example.com/path"
;

Signed URIs

Note: symfony/http-kernel is required to sign and verify URIs composer require symfony/http-kernel.

You can sign a URI:

$uri = Zenstruck\Uri\ParsedUri::wrap('https://example.com/some/path');

(string) $uri->sign('a secret'); // "https://example.com/some/path?_hash=..."

Temporary URIs

Make an expiring signed URI:

$uri = Zenstruck\Uri\ParsedUri::wrap('https://example.com/some/path');

(string) $uri->sign('a secret')->expires(new \DateTime('tomorrow')); // "https://example.com/some/path?_expires=...&_hash=..."

// # of seconds
(string) $uri->sign('a secret')->expires(3600); // "https://example.com/some/path?_expires=...&_hash=..."

// date string
(string) $uri->sign('a secret')->expires('+30 minutes'); // "https://example.com/some/path?_expires=...&_hash=..."

Single-Use URIs

These URIs are generated with a token that should change once the URI has been used.

Note: It is up to you to determine this token and depends on the context. This value MUST change after the token is successfully used, else it will still be valid.

$uri = Zenstruck\Uri\ParsedUri::wrap('https://example.com/some/path');

(string) $uri->sign('a secret')->singleUse('some-token'); // "https://example.com/some/path?_token=...&_hash=..."

Note: The URL is first hashed with this token, then hashed again with secret to ensure it hasn't been tampered with.

Signed URI Builder

Calling Zenstruck\Uri\ParsedUri::sign() returns a Zenstruck\Uri\Signed\Builder object that can be used to create single-use and temporary URIs.

$uri = Zenstruck\Uri\ParsedUri::wrap('https://example.com/some/path');

$builder = $uri->sign('a secret'); // Zenstruck\Uri\Signed\Builder

// create a single-use, temporary uri
$builder = $uri->sign('a secret')
    ->singleUse('some-token')
    ->expires('+30 minutes')
;

(string) $builder; // "https://example.com/some/path?_expires=...&_token=...&_hash=..."

Note: Zenstruck\Uri\Signed\Builder is immutable objects so any manipulations results in a new instance.

Verification

To verify a signed URI, create an instance of Zenstruck\Uri\ParsedUri and call isVerified() to get true/false or verify() to throw specific exceptions:

use Zenstruck\Uri\ParsedUri;
use Zenstruck\Uri\Signed\Exception\InvalidSignature;
use Zenstruck\Uri\Signed\Exception\ExpiredUri;
use Zenstruck\Uri\Signed\Exception\VerificationFailed;

$signedUri = ParsedUri::wrap('http://example.com/some/path?_hash=...');

$signedUri->isVerified('a secret'); // true/false

try {
    $signedUri->verify('a secret');
} catch (VerificationFailed $e) {
    $e::REASON; // ie "Invalid signature."
    $e->uri(); // \Zenstruck\Uri
}

// catch specific exceptions
try {
    $signedUri->verify('a secret');
} catch (InvalidSignature $e) {
    $e::REASON; // "Invalid signature."
    $e->uri(); // \Zenstruck\Uri
} catch (ExpiredUri $e) {
    $e::REASON; // "URI has expired."
    $e->uri(); // \Zenstruck\Uri
    $e->expiredAt(); // \DateTimeImmutable
}

Single-Use Verification

For validating single-use URIs, you need to pass a token to the verify methods:

use Zenstruck\Uri\Signed\Exception\InvalidSignature;
use Zenstruck\Uri\Signed\Exception\ExpiredUri;
use Zenstruck\Uri\Signed\Exception\UriAlreadyUsed;

/** @var \Zenstruck\Uri\ParsedUri $uri */

$uri->isVerified('a secret', 'some token'); // true/false

// catch specific exceptions
try {
    $uri->verify('a secret', 'some token');
} catch (InvalidSignature $e) {
    $e::REASON; // "Invalid signature."
    $e->uri(); // \Zenstruck\Uri
} catch (ExpiredUri $e) {
    $e::REASON; // "URI has expired."
    $e->uri(); // \Zenstruck\Uri
    $e->expiredAt(); // \DateTimeImmutable
} catch (UriAlreadyUsed $e) {
    $e::REASON; // "URI has already been used."
    $e->uri(); // \Zenstruck\Uri
}

SignedUri

Zenstruck\Uri\Signed\Builder::create() and Zenstruck\Uri\ParsedUri::verify() both return a Zenstruck\Uri\SignedUri object that implements Zenstruck\Uri and has some helpful methods.

Note: Zenstruck\Uri\SignedUri is always considered verified and cannot be manipulated.

$uri = Zenstruck\Uri\ParsedUri::wrap('https://example.com/some/path');

// create from the builder
$signedUri = $uri->sign('a secret')
    ->singleUse('a token')
    ->expires('tomorrow')
    ->create()
; // Zenstruck\Uri\SignedUri

// create from verify
$signedUri = $uri->verify('a secret'); // Zenstruck\Uri\SignedUri

$signedUri->isSingleUse(); // true
$signedUri->isTemporary(); // true
$signedUri->expiresAt(); // \DateTimeImmutable

// implements Zenstruck\Uri
$signedUri->query(); // Zenstruck\Uri\Query

UriLink

A PSR-13 Link implementation is provided with:

• Zenstruck\Uri\Link\UriLink (implements both Psr\Link\LinkInterface and Zenstruck\Uri).
• Zenstruck\Uri\Link\UriLinkProvider (implements Psr\Link\LinkProviderInterface and provides Zenstruck\Uri\Link\UriLink's).

TemplateUri

Note: rize/uri-template is required to use TemplateUri - composer require rize/uri-template.

Zenstruck\Uri\TemplateUri allows creating/manipulating RFC 6570 uri templates and implements Zenstruck\Uri.

use Zenstruck\Uri\TemplateUri;

// Expand
$uri = TemplateUri::expand('/repos/{owner}/{repo}', ['owner' => 'kbond', 'repo' => 'foundry']);

(string) $uri; // "/repos/kbond/foundry"
$uri->template(); // "/repos/{owner}/{repo}"
$uri->parameters()->all(); // ['owner' => 'kbond', 'repo' => 'foundry']

// Extract
$uri = TemplateUri::extract('/repos/{owner}/{repo}', '/repos/kbond/foundry');

(string) $uri; // "/repos/kbond/foundry"
$uri->template(); // "/repos/{owner}/{repo}"
$uri->parameters()->all(); // ['owner' => 'kbond', 'repo' => 'foundry']

Mailto

Note: Zenstruck\Uri\Mailto is an immutable object so any manipulations results in a new instance.

use Zenstruck\Uri\Mailto;

// Build
$mailto = Mailto::wrap('kevin@example.com')
    ->addTo('jane@example.com', 'Jane')
    ->addCc('ryan@example.com')
    ->addBcc('wouter@example.com')
    ->withSubject('my subject')
    ->withBody('some body')
    ->toString() // "mailto:kevin%40example.com%2CJane%20%3Cjane%40example.com%3E?cc=ryan%40example.com&bcc=wouter%40example.com&subject=my%20subject&body=some%20body"
;

// Parse/Read
$mailto = Mailto::new('mailto:kevin%40example.com%2CJane%20%3Cjane%40example.com%3E?cc=ryan%40example.com&bcc=wouter%40example.com&subject=my%20subject&body=some%20body');

$mailto->to(); // ["kevin@example.com", "Jane <jane@example.com>"]
$mailto->cc(); // ["ryan@example.com"]
$mailto->bcc(); // ["wouter@example.com"]
$mailto->subject(); // "my subject"
$mailto->body(); // "my body"
