class CardinalPoint extends Enum
{
    const NORTH = 'NORTH';    
    const EAST = 'EAST';    
    const WEST = 'WEST';  
    const SOUTH = 'SOUTH';
}


// Instantiate a new CardinalPoint instance
$direction = new CardinalPoint(CardinalPoint::NORTH);

// Since Enums have builtin validation,
// the following line would throw an InvalidArgumentException:
$direction = new CardinalPoint('North');

// However the following would work:
$direction = new CardinalPoint('NORTH');

// Using in functions or class methods 
public function changeDirection(CardinalPoint $direction)
{
    // Testing equlity with string
    if(!$direction->isEqualTo(new CardinalPoint(CardinalPoint::EAST))) {
        echo 'Not going East!';
    }

    // Since the constants are strings, it is also possible to compare
    // using loose comparison
    if($direction == CardinalPoint::NORTH) {
        echo 'Definitely going North!';
    }    
}
