How can PHP developers avoid code redundancy when implementing type validation in classes?

To avoid code redundancy when implementing type validation in classes, PHP developers can create a separate method for type validation that can be reused across different class methods. This way, the type validation logic is centralized and can be easily maintained or updated in one place. 

class MyClass {
    private function validateType($value, $type) {
        if (gettype($value) !== $type) {
            throw new InvalidArgumentException('Invalid type provided');
        }
    }

    public function setProperty(string $value) {
        $this->validateType($value, 'string');
        // Other logic for setting property
    }

    public function calculate(int $num1, int $num2) {
        $this->validateType($num1, 'integer');
        $this->validateType($num2, 'integer');
        // Other logic for calculation
    }
}
