Compose

PHP function composition, _(*1)

The composition can either be run directly from the static method or used as a trait in a class., _(*2)

Directly

As a trait

With static methods

setValue($value);
    }

    public function getValue(): string {
      return $this->value;
    }

    private function setValue(string $value) {
      $this->value = self::composeValue($value);
    }

    private static function composeValue(string $value): string {
      return self::compose($value, ['addA', 'addB', 'addC']);
    }

    private static function addA(string $string) {
      return "{$string}a";
    }

    private static function addB(string $string) {
      return "{$string}b";
    }

    private static function addC(string $string) {
      return "{$string}c";
    }
  }

  $stringAdder = new StringAdder('Value');
  echo $stringAdder->getValue(); // ValueABC
?>

With non-static methods

setValue($value);
    }

    public function getValue(): string {
      return $this->value;
    }

    private function setValue(string $value) {
      $this->value = self::composeValue($value);
    }

    private function composeValue(string $value): string {
      return $this->composeNonStatic($value, ['addA', 'addB', 'addC']);
    }

    private function addA(string $string) {
      return "{$string}a{$this->separator}";
    }

    private function addB(string $string) {
      return "{$string}b{$this->separator}";
    }

    private function addC(string $string) {
      return "{$string}c{$this->separator}";
    }
  }

  $stringAdder = new StringAdder('Value');
  echo $stringAdder->getValue(); // ValueA.B.C.
?>

With static and non-static methods

setValue($value);
    }

    public function getValue(): string {
      return $this->value;
    }

    private function setValue(string $value) {
