ArithmeticOperand Class

The abstract class ArithmeticOperand allows PHP classes that extend it to implement magic methods for native PHP arithmetic operations.

class CustomOperand extends \ArithmeticOperand
{
    public function __add(int|float|array|object $b);
    public function __mul(int|float|array|object $b);
    public function __pow(int|float|array|object $b);
    public function __div(int|float|array|object $b);
    public function __sub(int|float|array|object $b);
    public function __mod(int|float|array|object $b);
}

Using the example above, PHP will execute the code below:

$a = new CustomOperand();

$c = $a * 2;
