PHP can implement multiple interfaces.

In PHP, use the "implements" keyword to bind a class to one or more interfaces, allowing the class to implement all methods defined in the bound interface.

The following is a sample code:

interface Car {
    public function setModel($name);
    public function getModel();
}
interface Vehicle {
    public function setColor($rgb);
    public function getColor();
}
class MiniCar implements Car, Vehicle {
    private $model;
    private $color;
    public function setModel($name) {
        $this -> model = $name;
    }
    public function getModel() {
        return $this -> model;
    }
    public function setColor($rgb) {
        $this -> color = $rgb;
    }
    public function getColor() {
        return $this -> color;
    }
}

In the above code, two interfaces "Car" and "Vehicle" are defined, each interface has abstract methods. Next, a class named "MiniCar" is defined, which implements both interfaces, so MiniCar implements all methods of these two interfaces.
