Abstract value and enum objects

Value objects

class IntValue extends AbstractValue
{
publicstaticfunctionisValid($value)
{
returnis_int($value);
}
}
$x = newIntValue(10); // okprint$x->getValue(); // 10$y = newIntValue(10);
var_dump($x->equal($y)); // true$z = newIntValue('20'); // throws \UnexpectedValueException

Enum value object

All class defined constants are valid values, and magic method with same constant name can be called to instantiate Enum with that value.

class Gender extends AbstractEnum
{
constMALE = 'male';
constFEMALE = 'female';
privatestatic$titles = [
self::MALE => 'gender.male',
self::FEMALE => 'gender.female',
];
publicfunctiongetTitle()
{
returnself::$titles[$this->getValue()];
}
}
var_dump(Gender::all()); // ['male' => Gender() => 'female' => Gender() ]var_dump(Gender::values()); // [ 0 => 'male', 1 => 'female' ]$m = Gender::MALE();
print$m->getValue(); // maleprint$m->getTitle(); // gender.malevar_dump(Gender::isValid('male')); // truevar_dump(Gender::isValid('something')); // false
