News and Releases

• PHP 7.4.0 alpha 1 - The first alpha version of the new PHP branch has been released! Ahead of a six-month testing cycle , the final release is expected in late November.
  
  The number of new features is impressive: typed properties , arrow functions , FFI, preload and much more! A list of all changes to the UPGRADING document .
  An overview of new features can be found in the Habra translation New in PHP 7.4 or in a report by Nikita Popov on PHP Russia .
• DevConf 2019 (Moscow, June 21) - The tenth anniversary DevConf. By tradition, reports are selected by vote. Listen to the overview of submitted applications in the podcast Five-Minute PHP # 54 .

PHP internals

• [RFC] Allow throwing exceptions from __toString () - Offer accepted unanimously.
• [RFC] Numeric Literal Separator - The proposal crossed the threshold for voting, and so in PHP 7.4 it will be possible to use the underscore as a separator in numbers:
  
  

  $i = 197_823_459; // 197823459

• [RFC] Nullsafe Calls - An old proposal is being discussed again at Internals. It considers the possibility of adding a new operator ?->that would allow making safe chains of method calls, in case the return value can be null:
  
  

  $o?->mayFail1()?->mayFail2()?->mayFail3()?->mayFail4();

  
  There is a similar offer in ECMAScript , but in Hack this feature is already implemented .
• [RFC] Alternative “use” syntax for Closures - The author of the proposal considers the use syntax in closures not very convenient and suggests transferring it to the function body:
  
  
  Hidden text

  // Так сейчас
  $closure = function (
      ArgumentType $argument1,
      ArgumentType $argument2,
      ArgumentType $argument3,
      ArgumentType $argument4
  ) use ($importVariable1, &$importVariable2, $importVariable3, &$importVariable4): ReturnType {
      // ...
  };
  // Предлагается вот так
  $closure = function (
      ArgumentType $argument1,
      ArgumentType $argument2,
      ArgumentType $argument3,
      ArgumentType $argument4
  ): ReturnType {
      use $importVariable1, &$importVariable2;
      use $importVariable3, &$importVariable4;
      // ...
  };
