    News and Releases




    Php


    • RFC: Null Coalesce Equal Operator - It is proposed to implement a combined operator ??=in addition to the usual ??one added in PHP 7.
      // Следующие две строки эквивалентны
$this->request->data['comments']['user_id'] = $this->request->data['comments']['user_id'] ?? 'value'; 
$this->request->data['comments']['user_id'] ??= 'value';

    • RFC: Short ternary Equal Operator - It is also proposed to implement a combined ternary operator:
      $x = $x ?: $y; 
$x ?:= $y;

    • RFC: “var” Deprecation - It is suggested that the keyword be deprecated var. Interestingly, this keyword was already deprecated in versions 5.0.0 - 5.1.2, and at the moment it is only a synonym public.
    • RFC: Catching Multiple Exception Types - The opportunity to catch several types of exceptions in one catch block is proposed for consideration:
      try {   
    // Some code...
} catch (ExceptionType1 | ExceptionType2 $e) {
   // Code to handle the exception
} catch (\Exception $e) {
   // ...
}

    • RFC: Traits with interfaces - It is proposed to make it possible to use interfaces in traits:
      interface I {
    function foo();
}
trait T implements I {
    function foo() {
    }
}
