// New instance

// or

// Array instances
DriveWheel::all(); // [DriveWheel::front(), DriveWheel::rear(), DriveWheel::allDrive()]
DriveWheel::all(['FWD', 'RWD'], $reverse = false, $property = 'code'); // [DriveWheel::front(), DriveWheel::rear()]
DriveWheel::all([1, 2], $reverse = true); // [DriveWheel::allDrive()]

// Methods
$drive->toId();    // 1
$drive->to('id');  // 1
(string) $drive;   // '1'

$drive->toName(); // 'front'

$drive->toCode();   // 'FWD'
$drive->to('code'); // 'FWD'

$drive->isFront(); // true
$drive->isRear();  // false

$drive->eq(DriveWheel::front()); // false
$drive->eq(DriveWheel::rear());  // false

Design

• All constants MUST be private
• All constants MUST be type of integer
• All properties MUST NOT be public
• All properties MUST be static
• Properties MUST contain values for all defined constants

Doctrine

This lib distributed with Type class for Doctrine to easy configure each Enum as Doctrine Type., _(*2)

Premier\Enum\Doctrine\EnumType::register(Premier\Enum\Gender::class, 'gender_enum', $property = 'id');

class Entity 
{
    /**
    * @var Gender
    * 
    * @ORM\Column(type="gender_enum") 
    */
    public $gender;
}
