Backed Enum Value Validator

Laminas\Validator\BackedEnumValue allows you to validate that a string or numeric value is a valid value for a specified enum.

Supported Options

The following options are supported for Laminas\Validator\BackedEnumValue:

• enum: The backed enum class you wish to test against

Basic Usage

enum MyEnum: string {
    case Something = 'Some Value';
    case OtherThing = 'Other Value';
}

$validator = new Laminas\Validator\BackedEnumValue([
    'enum' => MyEnum::class,
]);

if ($validator->isValid('Some Value')) {
    // $value is a valid value for `MyEnum`
} else {
    // $value is not a known value in `MyEnum`
    foreach ($validator->getMessages() as $message) {
        echo "$message\n";
    }
}

Unit enums are not supported by this validator. To validate enum cases as opposed to values, see the EnumCase validator.
