PHP Annotated – January 2025

Roman Pronskiy

Welcome to the January edition of PHP Annotated! This recap is carefully handcrafted and brings you the most interesting developments in the PHP community over the past couple of months, so you don’t have to sift through the noise, we’ve done it for you.

Highlights

• PHP 8.4

  PHP 8.4 was officially released on November 21, 2024, and by now, version 8.4.3 is already available.

  This major language update brings many new features, such as property hooks, asymmetric visibility, an updated DOM API, performance improvements, bug fixes, and general code cleanup.

  If you want to learn more about all the goodies in the release, visit php.watch and stitcher.io.

  There are also some lesser known improvements that you can learn more about from the Tideways blog:

  • PHP 8.4 improves Closure Naming for simplified debugging.
  • What’s new in PHP 8.4 in terms of performance, debugging, and operations.

  Install or upgrade to PHP 8.4

  • Windows: Compiled binaries available at windows.php.net.
  • Fedora/RHEL/CentOS: Available as a software collection (php84) from the Remi repo.
  • macOS: PHP 8.4 can be installed via Homebrew using the shivammathur/homebrew-php tap.
  • Docker: PHP 8.4 images are now available on Docker Hub with 8.4 tags.
  • Herd also comes with PHP 8.4 supported.

  Watch a 📺 Celebrating PHP 8.4 stream with Nicolas, Brent, and Roman:
  

• PHP 8.2 goes in security-fixes-only phase

  Starting this year, PHP versions now follow a four-year support timeline: two years of active support followed by two years of security fixes.

  For PHP 8.1 security patches will be provided until December 31, 2025, while PHP 8.2 will be maintained until December 31, 2026. The recent PHP 8.2.27 release marked the end of its active support phase.

• PHPStan 2.0 has been released

  This update introduces Level 10 code analysis with stricter handling of mixed types, and adds support for the List type. You can also expect reduced memory consumption and improved performance.

  Markus Staab shares interesting technical insights about improving PHPStan:
  A mixed type PHPStan journey, PHPStan performance on different hardware, My new PHPStan focus: multi-phpversion support.

• 🎂 The PHP Foundation turned three

  The PHP Foundation was established three years ago. Over the past year, the PHP Foundation has supported the work of ten core developers, and made a significant contribution to the PHP language.

  Consider supporting the PHP Foundation via OpenCollective or GitHub Sponsors.

  The PHP Foundation has been also active with developments:

  • PHP 8.4: How Property Hooks Happened – Larry Garfield details the decade-long journey of implementing Property Hooks in PHP 8.4.
  • The PHP Installer for Extensions php/pie reached version 0.5!
    Learn more about it from Pie: new extension installer for PHP post by Grzegorz Korba.

• Rector 2.0

  This major release updates dependencies (PHPStan 2 and PHP-Parser 5), runs 10–15% faster, and has 5 new features.

• FrankenPHP 1.3

  In this release, expect performance improvements, watcher mode, dedicated Prometheus metrics, and more.

• Conductor – Automatic dependency updates for Composer

  The Packagist team announced a new tool that is similar to Dependabot, but specifically tailored to PHP projects.

• You can now run code examples directly on the php.net website

  

PHP Core

• ✅ RFC: Add persistent curl share handles

  PHP 8.5 will bring a new function curl_share_init_persistent(), which would allow cURL handles to be stored in global memory and reused in subsequent requests.

  Persistence allows PHP scripts to eliminate the overhead of establishing a connection (and DNS lookups, SSL session IDs, etc.) and can improve performance and reliability.

• ✅ RFC: Support Closures in constant expressions

  In PHP 8.5 it will be possible to use closures in previously

  • In attribute parameters,
  • As default values of properties and parameters.
  • Constants and class constants.

  <?php
  
  class Foo
  {
      public static Closure $callback = static function ($item) { echo "Hello world"; };
  }
  
  
  function my_array_filter(
      array $array,
      Closure $callback = static function ($item) { return !empty($item); },
  ) {
      // ...
  }
  

• ✅ RFC: Attributes on Constants

  Attributes were first introduced in the RFC: Attributes v2. Daniel Scherzer proposes to add support for attributes on compile-time non-class constants.

  #[\MyAttribute]
  const EXAMPLE = 1;
  

• ✅ RFC: Error Backtraces v2

  Previously, unlike exceptions, PHP errors did not provide backtraces, which made it difficult to figure out their underlying cause. PHP 8.5 will come with a new ini setting fatal_error_backtraces=1 which will generate detailed error messages and trace for E_ERRORs.

• 📣 RFC: Records vs. RFC: Data Class vs. RFC: Structs

  Apparently, there is a big interest in the community to add a simple native way of creating Value Objects in PHP.
