文档 | Cycle ORM

该包提供使用PHP属性定义Cycle ORM模式的能力。

使用方法

use Cycle\Annotated\Annotation\Entity;
use Cycle\Annotated\Annotation\Column;

#[Entity]
class User
{
    #[Column(type: 'primary')]
    private int $id;

    #[Column(type: 'string(32)')]
    private string $login;

    #[Column(type: 'enum(active,disabled)')]
    private string $status;

    #[Column(type: 'decimal(5,5)')]
    private $balance;
}

关系

#[Entity]
class User
{
    // ...

    #[HasOne(target: Address::class)]
    public ?Address $address;
}

use Cycle\Annotated\Annotation\Relation\HasMany;

#[Entity]
class User
{
    // ...

    #[HasMany(target: Post::class)]
    private array $posts;
}
