PSR-7 URI Implementation

A PHP implementation of PSR-7 UriInterface with additional utility methods.

Features

Implements PSR-7 UriInterface, with two deliberate differences for connection strings (see PSR-7 differences)
Includes additional utility methods via CustomUriInterface
Supports RFC3986 URI specification
Type-safe implementation with PHP 8 attributes and strict typing
Immutable class design pattern

PSR-7 differences

The URI is also used for connection strings (mysql://host:3306/db, h:9092), so two PSR-7 recommendations are not followed:

The standard port is kept. https://host:443 keeps 443 in getPort(), getAuthority() and the string (PSR-7 SHOULD return null and leave it out).
A URI without a scheme is written without //. new Uri('h:9092') is read as host h and port 9092 and written back as h:9092, not //h:9092. A URI with a scheme always has // after it, even without a host (sqlite:///tmp/db).

URI Encoding Behavior

PSR-7 requires URI compliant with RFC3986. This means the URI output will always be URL encoded. This applies to both creating a new instance and the string representation.

Examples:

// Creating a URI with special characters in the password
$uri = \ByJG\Util\Uri::getInstance("https://user:pa&@host");
print((string)$uri); // Will print "https://user:pa%26@host"

// Creating a URI with already encoded characters
$uri = \ByJG\Util\Uri::getInstance("https://user:pa%26@host");
print((string)$uri); // Will print "https://user:pa%26@host"

// Using withUserInfo with unencoded password
$uri = \ByJG\Util\Uri::getInstance("https://host")
    ->withUserInfo("user", "pa&");
print((string)$uri); // Will print "https://user:pa%26@host"

// Using withUserInfo with already encoded password
$uri = \ByJG\Util\Uri::getInstance("https://host")
    ->withUserInfo("user", "pa%26");
print((string)$uri); // Will print "https://user:pa%2526@host"

// The username is decoded by getUsername() and encoded in the string form, like the password
$uri = \ByJG\Util\Uri::getInstance("https://email@host.com:pass@host");
print($uri->getUsername()); // Will print "email@host.com"
print((string)$uri); // Will print "https://email%40host.com:pass@host"

Additional Methods

This implementation extends PSR-7 UriInterface with the following additional methods through \ByJG\Util\CustomUriInterface:

Method	Description
`getUsername(): ?string`	Get the decoded username of the URI
`getPassword(): ?string`	Get the decoded password of the URI
`getQueryPart(string $key): ?string`	Get a specific query parameter by key
`getQueryParts(string $key): array`	Get every value of a query parameter
`withQueryKeyValue(string $key, string $value, bool $isEncoded = false): self`	Add or update a query parameter
`hasQueryKey(string $key): bool`	Check if a query parameter exists

Static Factory Methods

The class provides convenient static factory methods:

// Create from string
$uri = Uri::getInstance("https://example.com/path?query=value#fragment");

// Create from another UriInterface
$uri2 = Uri::getInstance($uri);
