Php internals

[RFC] New custom object serialization mechanism - Offer accepted. In PHP 7.4, a new object serialization mechanism has been implemented and two magic methods have been added:

Hidden text

// Returns array containing all the necessary state of the object. public function __serialize(): array; // Restores the object state from the given data array. public function __unserialize(array $data): void;

[RFC] JIT - JIT for PHP supports Windows and ZTS. The latter means that you can use in multi-threaded applications. The proposal has already started a vote, judging by the course of which, it is likely to be accepted for PHP 8.0, but the idea of including in PHP 7.4 will not receive sufficient support.
The topic also includes a post with benchmarks of the Redis server for PHP clue / php-redis-server , where the author received an increase of ~ 4-23% on the version with JIT.
[RFC] Arrow Functions 2.0 - Third attempt to implement short lambda in PHP. This time the syntax is suggested.
```
 $y = 1; $fn1 = fn($x) => $x + $y; 
```
In this case, the variables from the external scopa are automatically assigned by value and do not use use ().
Internals also discusses alternate syntax options:
```
 ($x) ==> $x + $y; 
```
```
 \($x) => $x + $y; 
```
[RFC] Generator comprehensions - The concept is framed in a complete proposal for the implementation of list inclusion (list comprehension). Compared with the concept, as in short lambdas, there is no need to use use() :
Hidden text
```
 $y = 3; $gen = [for $list as $x if $x % 2 yield $x * $y]; 
```
[RFC] Deprecate curly braces array access - At this point, you can use both square and curly brackets to access the elements of arrays and strings. And although they are equivalent, the curly brackets still do not work, for example, to add an element to the “$arr{} = 1;” array or to declare the “$a={1,2};” array. It is proposed that the braces in this context be rejected and that only square brackets be left. Do you use braces?

Entertaining

ircmaxell / php-compiler - The long-abandoned compiler idea for PHP from Anthony Ferrara got reincarnated thanks to FFI in PHP 7.4. Theoretically, the compiler is able to generate native machine code and produce a binary executable without a PHP virtual machine. In practice, this is only a concept that supports nothing at all, but the idea is interesting.

Thanks for attention!
