1 <?php 2 3 class MilesCalculator implements Calculator 4 { 5 public function calculate(int $distance, bool $businessClass, bool $flyingCl\ 6 ubMember): int 7 { 8 $multiplier = $this->getMultiplier($businessClass, $flyingClubMember); 9 10 return $distance * $multiplier; 11 } 12 13 private function getMultiplier(bool $businessClass, bool $flyingClubMember):\ 14 int 15 { 16 $multiplier = 1; 17 18 if ($businessClass === true) { 19 $multiplier *= 2; 20 } 21 22 if ($flyingClubMember === true) { 23 $multiplier *= 2; 24 } 25 26 return $multiplier; 27 } 28 }
