PHP 8.5 Released

URI Extension

PHP 8.5 adds a built-in URI extension to parse, normalize, and handle URLs following RFC 3986 and WHATWG URL standards.

Pipe Operator

The |> operator enables chaining callables left-to-right, passing values smoothly through multiple functions without intermediary variables.

Clone With

Clone objects and update properties with the new clone() syntax, making the "with-er" pattern simple for readonly classes.

#[\NoDiscard] Attribute

The #[\NoDiscard] attribute warns when a return value isn’t used, helping prevent mistakes and improving overall API safety.

Closures and First-Class Callables in Constant Expressions

Static closures and first-class callables can now be used in constant expressions, such as attribute parameters.

Persistent cURL Share Handles

Handles can now be persisted across multiple PHP requests, avoiding the cost of repeated connection initialization to the same hosts.

$components = parse_url('https://php.net/releases/8.4/en.php');

var_dump($components['host']);
// string(7) "php.net"

use Uri\Rfc3986\Uri;

$uri = new Uri('https://php.net/releases/8.5/en.php');

var_dump($uri->getHost());
// string(7) "php.net"

            trim($title)

    )
);

var_dump($slug);
// string(15) "php-85-released"

$title = ' PHP 8.5 Released ';

$slug = $title

    |> (fn($str) => str_replace(' ', '-', $str))

    |> strtolower(...);
