PHP Annotated – December 2022

PHP Annotated Monthly

Greetings everyone!

Welcome to the December installment of PHP Annotated, where we’ll catch up on the most exciting things that have happened in the PHP world over the last month, including curated news, articles, tools, and videos.


  • 🎉 PHP 8.2.0 released!

    PHP 8.2 is a major update of the PHP language.It contains new features, including readonly classes, DNF types, null/false/true as stand-alone types, a new randomizer API, and constant in traits.

    The release comes with a few deprecations, with the deprecated dynamic properties being probably the most significant one. There are also performance improvements, as usual.

    For a detailed list of what’s new in PHP 8.2, check out the release page.
    Also check out PHP 8.2 Highlights on PHP.Watch and a video overview of PHP 8.2 by my colleague Brent.

PHP Core

Most of the Core news is covered in detail in the PHP Core Roundup series from the PHP Foundation, so we’ll only mention it briefly:

  • 📣 PHP RFC: Dynamic class constant fetch #PHP 8.3
    Ilija Tovilo proposed introducing a syntax for looking up class constants.

    class Foo {    
        const BAR = 'bar';
    $bar = 'BAR';
    // This is currently a syntax error
    echo Foo::{$bar}; 
    // Instead, the `constant` function must be used
    echo constant(Foo::class . '::' . $bar);
  • 📣 RFC: Arbitrary static variable initializers #PHP 8.3
    Ilija Tovilo proposed extending the syntax that allows the static variable initializer to contain arbitrary expressions.

    function bar() {    
        echo "bar() called\n";
        return 1;
    function foo() {
        static $i = bar();
        echo $i++, "\n";
  • 📣 RFC: Readonly amendments #PHP 8.3
    Nicolas Grekas and Máté Kocsis proposed improving readonly properties and classes, allowing non-readonly classes to extend readonly classes and allowing readonly properties to reinitialize during cloning:

    readonly class Foo {
        public function __construct(
            public DateTime $bar
        ) {}
        public function __clone()
            $this->bar = clone $this->bar;
    $foo = new Foo(new DateTime());
    $foo2 = clone $foo;
  • 📊 RFC: More Appropriate Date/Time Exceptions #PHP 8.3
    Derick Rethans proposed introducing Date/Time extension specific exceptions and errors where this makes sense.
  • 📣 RFC: List\unique() and Assoc\unique() #PHP 8.3
    Ilija Tovilo proposed adding two new functions for the cases that are not supported by array_unique():

    List\unique([1, 2, 3, 1, '2', 3.0, new Foo, ['bar']]);
    // > [1, 2, 3, '2', 3.0, Foo, ['bar']]
    Assoc\unique(['foo' => 'foo', 'bar' => 'bar', 'baz' => 'foo']);
    // > ['foo' => 'foo', 'bar' => 'bar']
  • 📣 RFC: Unicode Text Processing #PHP 8.3
    Derick Rethans suggests introducing a new Text class to make using and processing Unicode text significantly more developer friendly and without having to know all the intricacies of Unicode text processing.

    $content = new Text('नमस्ते दुनिया');
    if ($content->toLower()->startsWith('नमस्ते')) {
      // ...


  • Marcel Pociot built a neat GitHub bot that evaluates PHP code blocks in GH issues if you mention it @phptinker:
  • ramsey/uuid – A new version of package for generating universally unique identifiers comes with support for UUID v8 and custom UUIDs.
  • loophp/collection – A memory friendly and modular collection class released a new major version, 7.0.0.

  • ScriptFUSION/Porter – Durable and asynchronous data imports for consuming data at scale and publishing testable SDKs.
  • ChatGPT is taking over everything, so you may want to check out the PHP client for OpenAI:
  • qossmic/deptrac 1.0 – Project architecture analysis tool for determining dependencies between application layers.
  • revoltphp/event-loop 1.0.0 – This event loop is a joint effort between ReactPHP and Amphp maintainers. It is now ready for production use, has been tested in various different applications and scenarios, and fully supports fibers.
