Enjoy reading!

News and Releases

• PSR-14 Event Dispatcher - officially moved to the review stage .
• PSD-12 Extended Code Style - A new coding style standard extends and complements PSR-2 and is intended to replace it. Also under review.
• PHP 7.3.2
• PHP 7.2.15
• PHPUnit 8

Php internals

• The PHP-7.4 branch has been created , and the PHP master repository is now aimed at PHP 8.0. This means that work on PHP 8.0 has already started, and PHP 7.4 will be developed in parallel. So, in PHP 8, a whole bunch of obsolete features have been removed .
• [RFC] JIT - An old idea with JIT in PHP has finally been realized through the efforts of Dmitry Stogov. JIT is implemented as an independent part of OPcache, and can be turned on / off even at runtime. PHP 8 is considered as the target version, but it is possible to enable it in PHP 7.4 as an experimental disabled feature by default. According to Nikita Popov's benchmarks, JIT gives an increase of 30% for PHP-Parser and about 5% for amphp / http-server . There is currently no Windows support, which is controversial in Internals
  In the meantime, you can already try PHP + JIT using Docker images (thanks @dmitrybalabka ). Also in the topic is a great post about what JIT means for PHP users .
• [RFC] Consistent type errors for internal functions - Another RFC from Nikita Popov. It is proposed to make it so that in PHP 8 all built-in functions throw a TypeError when the parameters of the wrong type are passed instead of the returns and null returns.

  Instead:

   var_dump(strlen(new stdClass)); // Warning: strlen() expects parameter 1 to be string, object given // NULL 

  
  Will be:
  

   declare(strict_types=1); var_dump(strlen(new stdClass)); // TypeError: strlen() expects parameter 1 to be string, object given 

  
  
• [RFC] RFC Workflow & Voting (2019 update) - Attempting to somewhat tighten the RFC vote and bureaucratize the process met a storm of criticism in the Internals. So much so that alternative offers have appeared. Zeev Suraski, his own version, promised to rework and take into account the criticism.
• [RFC] Weak References - It is proposed to add the WeakReference class to implement weak links, which will allow the developer to save the link to the object without preventing it from being deleted by the garbage collector. This can be especially useful for all sorts of caches.
• [RFC] Allow void return type variance - Offer to implement the ability to override the return type of void in inheritor methods. Appeared in the wake of changing the signature of the setUp() method and several others in PHPUnit 8.

   class Foo { function method1 (): void {} function method2 () {} } class Bar extends Foo { function method1 (): array { return []; } function method2 (): array { return []; } } class Baz extends Foo { function method1 () { return 42; } function method2 () { return 42; } } 

• [RFC] Mixed typehint - And here it is proposed to add a mixed tag. This will indicate that the function can take (or return) values ​​of different types.
• [RFC] Annotations 2.0 - A draft proposal for full annotations. Earlier there were attempts to implement simple annotations and attributes . In the meantime, you can use a great plugin for annotations in PhpStorm .
