How to rewrite a switch into polymorphic classes?

I have this classic switch, I know that when we are building classes is not a good practice use the switch method, so, how I can rebuild this into a class without using switch but Polymorphism and I would like to understand the approach.

/**
 * globals below are holding unique id 
 * $Franklin['Franklin_id'] , 
 * $Granny_Smith['Granny_Smith_id'] , 
 * etc etc...
 */
 
global $Fuji, $Gala, $Franklin, $Granny_Smith;

switch($Apple) {
  case 'Fuji':
    $Color = 'Yellowish green';
    $Size = 'medium';
    $Origin = 'Japan';
    $Season = 'October - January';
    $AppleId = $Fuji['Fuji_id']; 
  break;
  case 'Gala':
    $Color = 'yellow';
    $Size = 'medium';
    $Origin = 'New Zealand';
    $Season = 'October - January';
    $AppleId = $Gala['Gala_id'];
  break;
  case 'Franklin':
    $Color = 'Well-colored';
    $Size = 'medium';
    $Origin = 'Ohio';
    $Season = 'October';
    $AppleId = $Franklin['Franklin_id'];
  break;
  case 'Granny_Smith':
    $Color = 'Green';
    $Size = 'medium';
    $Origin = 'Australia';
    $Season = 'October - December';
    $AppleId = $Granny_Smith['Granny_Smith_id'];
  break;
}

then I would like to be able to use it something like this

$AppleProps = new getApple('Granny_Smith'); // $AppleProps->Color, etc etc

I'm not complete sure what your IDs mean, but this code gives you an AppleFactory that will "stamp" each new apple with a unique ID.

class AppleFactory {

    static $id = 0;

    static public function getApple($className) {
        $apple = new $className();
        $apple->id = self::$id++;
        return $apple;
    }

}

class Apple {

    public $id;
    public $color;
    public $size;
    public $origin;
    public $season;

}

class GrannySmith extends Apple {

    public function __construct() {
        $this->color = 'Green';
        $this->size = 'medium';
        $this->origin = 'Australia';
        $this->season = 'October - Desember';
    }

}

$a = AppleFactory::getApple('GrannySmith');
print_r($a);
