PHP internals

[RFC] Reclassifying engine warnings - It is proposed to review the dropped notices and vorings in the PHP engine and adjust the classification where necessary. In many cases, it is proposed to increase the error level: Notice -> Warning, for example, when trying to get a property from a non-object, and Warning -> Error exception, for example, when trying to use a scalar as an array. Well, "Undefined variable" will throw Warning.
[RFC] Union Types v2 - It is proposed to introduce combined types - this means that the variable can take one of the listed types. De facto concatenated types have long been used in PHPDoc, but now they will actually be checked by the interpreter itself.

The proposed syntax T1|T2|...

can be used wherever types can be specified now:
Hidden text
```
 class Number { private int|float $number; public function setNumber(int|float $number): void { $this->number = $number; } public function getNumber(): int|float { return $this->number; } }
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     
```
As an experiment, the RFC is designed as a pull request and anyone can comment or express a reaction in the form of emoji. The final vote will be held as before on wiki.php.net. Judging by the message of Nikita , the first experiment went well and many valuable comments were received from the community.
error_reporting = E_ALL in PHP 8 - In PHP 8, the default error level will be set to E_ALL

instead of the current one: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
