A lightweight DTO library inspired by spatie/data-transfer-object.

• Attribute based
• Built-in Enum conversion
• No external dependency

Install

composer require hided62/ldto

use LDTO\Attr\Convert;
use LDTO\Attr\JsonString;
use LDTO\Attr\NullIsUndefined;
use LDTO\Attr\RawName;
use LDTO\Converter\DateTimeConverter;
