  • The New Life of PHP – The PHP Foundation

    JetBrains teamed up with Automattic (WordPress), Acquia (Drupal), Laravel, Private Packagist (Composer), Symfony, Zend, Craft CMS, Tideways and PrestaShop to form a non-profit organization PHP Foundation, whose mission is to ensure the long-term development of the PHP language

    One of the reasons for the creation of the organization was the change in the interests of Nikita Popov. He has been working with PHP for 10 years and for the last 3 years Nikita’s work on PHP has been paid for by JetBrains. Besides PHP, Nikita has contributed to LLVM and Rust for a long time. And now he decided to focus his professional activities on LLVM and from December 1 Nikita will move to work in another company. Nikita will still be part of the PHP community, but there will be much less contributing.

    The primary task of the foundation is to employ developers on a full or part-time basis, who will deal with the core of the PHP interpreter in the repository. php / php-src

    I told in detail about the history of the foundation and the work of the fund on the stream: video About PHP Foundation with Roman Pronsky

    You can read more about the foundation and the history of its influence on PHP in post by Joe Watkins (made a great contribution to the creation of the fund).

    We will post updates about the work on Twitter: @ThePHPF

  • Composer gets even faster

    In the next release, Pool Optimizer will be enabled by default – this will noticeably speed up the update installation operations, and the more complex the set of dependencies in composer.json, the more significant the speed gain and less memory consumption.

  • [RFC] Deprecate dynamic properties

    Despite numerous controversies, the proposal was accepted with a margin of only two votes 52:25!

    This means that in PHP 8.2 dynamic (undeclared) properties will be deprecated, and in PHP 9.0 they will be completely removed. Read more in PHP Digest # 215.

    In the topic, a fresh article from Larry Garfield about PHP evolution controversy

  • Came out Doctrine DBAL 3.2.0

    Also discovered critical SQL injection in doctrine / dbal 3.0.0 – 3.1.3you should upgrade to 3.1.4 or newer immediately.

  • [RFC] Readonly classes

    Máté Kocsis offers readonly classes for PHP 8.2. In fact, it is just a class in which all properties are readonly and dynamic properties are prohibited. That is, it’s a little syntactic sugar for convenience.

    readonly class Foo {
        public string $prop;
    }
    

    Equivalent to:

    class Foo {
        public readonly string $prop;
        public function __set($name, $value) {
            throw new Error('Cannot create dynamic property');
        }
    }
